Getting Ready for Flight
Your Hobbico SuperStar trainer is ready for takeoff in as little as 20 hours. Your hobby dealer or flying instructor (see next page) can help you decide what accessories you’ll need for flight. Most are one-time only purchases—and your instructor will probably allow you to use his field box until you can outfit your own with a glow plug starter, fuel pump, and “chicken stick" or electric starter. You will need to provide your own fuel. Use glow fuel with a 10-15% nitro blend to keep your engine performing at its peak...and your SuperStar will have the power to make you an accomplished pilot!
Other items youll need:
Glues
Choose 6-minute and 30-minute epoxy, such as Great Planes Pro
TM
Epoxy, which has been formulated especially for R/C model building. Pro Epoxies offer a strong bond and a variety of curing times suited for every step of assembly. You’ll also need a thin instant-setting CA (cyanoacrylate), a thicker CA+, plus rubbing alcohol for easy epoxy cleanup.
Model Engine
Power your SuperStar with any high-quality, .60­size model engine. The O.S. .60 FP, or SuperTigre S-61K are fine engines for this plane. Look for fea­tures such as easy break-in, easy starting, efficient carburetion and low maintenance. Check the manufacturer’s recommendations for propellers to use with your engine.
Radio Equipment
To let you send the commands that control your SuperStar’s “flight path,” you’ll need a 4-channel air­craft radio system with four standard servos. Many 4­channel radios include just three servos. You may need to purchase the fourth separately. The servos and radio receiver will be mounted on-board your model and need to be cushioned from jolts and vibration. One­half inch thick foam rubber sheets (HCAQ1050) are available for this purpose
.
Hardware
Tools and accessories required for assembly include a hobby knife; small and large Phillips screwdrivers; needle nose pliers; drill with 1/16”, 3/32” and 5/32” bits; ruler; #64 rubber bands; 1 foot of medium fuel tubing; and petroleum jelly.
Other General Items Required
Epoxy Brushes (GPMR8062) Mixing Sticks (GPMR8055) Clothespins Foam Rubber (HCAQ1050) T-Pins (HCAR5150) Masking Tape Drill and Drill Bits -
1/16”, 3/32” and 5/32” Phillips Screwdriver String
Felt Tip Pen Sanding Block Adjustable Wrench Masking Tape Paper Towels

The best way to begin flying
your SuperStar is with an experi­enced R/C pilot or flying instruc­tor at your side. You’ll learn faster, and avoid risking your model before you’re truly ready to solo.
Where do you find an instructor? Ask at your local hobby shop. They’ll have information about flying clubs in your area whose membership includes qualified instructors. You should also join the Academy of Model Aeronautics (AMA), a 165,000
member-strong national organization with more than 2,300 chartered clubs across the country. Through any one of them, instructor training programs are available. Contact the AMA at the address or phone number below:

Before you fly:
1. Make sure that no other fliers are using your radio frequency.
2. Your radio transmitter must be the FIRST thing you turn ON, and the LAST thing you turn OFF.
3. Double check all control surfaces.
4. Make sure that the transmitter & receiver batteries are fully charged.
Fuel storage and care:
1. Do not smoke near your engine or fuel.
2. Store all engine fuel in a safe, cool, dry place, away from chil­dren and pets. Model fuel will evaporate, so make sure that you always store it with the cap secure.
1. Always wear safety glasses.
2. Make certain that your glow plug clip is securely attached to the glow plug—and cannot pop off, possibly falling into the spinning propeller.
3. Use a “chicken stick” or electric starter to start the engine— NOT your fingers.
4. Make sure that the wires from your starter and glow plug clip cannot become tangled with the spinning propeller.
5. Do not stand at the side of the propeller when you start or run the engine. Even at idle speed,
the spinning propeller will be nearly invisible.
6. If any engine adjustments are necessary, approach the engine only from behind the spinning propeller.
Please follow these safety precautions:

Special Note:
You should charge your radio system before starting to build. Following the manufacturer’s directions, connect your transmitter and receiver batteries to the system’s charger. This way the radio will be ready when it is time to install the components.
Prepare the wing joiners
1. Locate the 1/8" (3mm) die-cut plywood wing
joiners and separate the three individual joiners from the die-cut plywood sheet using a hobby knife. Arrange the three "V"-shaped joiners in the same orientation as they will be glued together.
Glue the wing joiners
Note: Please read steps 2 through 4 before gluing.
2. Mix approximately 1/4oz. (7.5ml) of 6-minute
epoxy. Using a mixing stick or epoxy brush, apply an
even coat of epoxy on both sides of one of the wing joiners. Sandwich this coated joiner between the remaining two. Quickly proceed through the following steps (3 and 4) before the glue cures.
Remove the excess epoxy
3. Excess epoxy will squeeze out of the seams
between the joiners and must be removed before
the epoxy is allowed to cure. Use a paper towel dampened with rubbing alcohol to remove the excess epoxy.
Clamp the wing joiner
4. Use clothespins to clamp the wing joiners firmly
together. If any more epoxy squeezes out, remove it using a paper towel. Make sure the joiners are evenly lined up with each other.
Assembling the Wing
Page 7

Mark the centerline on the joiner
5. After the epoxy has cured and the clothespins
have been removed, draw a centerline on both sides of the plywood wing joiners and the two balsa 5/16” x 1-7/16" (8mm x 36mm) aileron servo tray mounting blocks. Use the plywood joiner as a template to mark the wing dihedral angle on both of the balsa aileron servo tray mounting blocks. Put these mounting blocks aside for use in later steps.
Even the edges
6. Using a flat sanding block or similar tool, sand
the wing roots so they will seat together with no gaps. Do not sand off too much or the dihedral angle could change.
Mark the wing cavity
7. Lay the wing halves on the work surface with the
white, flat side facing up. Place a mark at the trailing edge of the wing joiner cavity, aft of the plywood brace on each wing half. This wing joiner locator line will serve as a guide when cutting out the aileron servo hole.
Trial fit the wing joiner
8. Trial fit the wing joiner in both wings by sliding
the joiner into the joiner cavity in the wing. The joiner should slide in with little resistance up to the centerline.Trial fit the wing halves together. The two panels should fit flush with no gaps.
Sand the joiner
9. If the wing joiner will not fit in the cavity, lightly
sand any excess epoxy and uneven surfaces from the joiner edges, sides and ends. Caution: A snug fit is
desirable between the joiner and the wing cavity. Do not sand excessively.
Viewing the wing dihedral
10. Pay close attention to the orientation of the
wing joiner in relation to the dihedral of the wings as shown.
Note: When performing the following steps 11 and 12, be sure to use a sufficient amount of epoxy to form a complete and solid bond between the plywood wing joiner and the two wing halves. This is the most important glue joint in the entire airplane.

Glue the joiner into the wing
11. Mix 1/4oz. (7.5ml) of 30-minute epoxy to glue
the joiner into one wing half. Use a mixing stick or epoxy brush to apply epoxy to all four sides of the joiner cavity wall. Insert the joiner into the cavity up to the centerline marked on the joiner plate. Be sure you are installing the joiner in the correct orientation to the wing. Clean the excess epoxy from the wing root rib. You must be sure all the excess glue is removed from the wing root or the wings will not fit together correctly. Allow enough time for the epoxy to fully cure before proceeding to the next step.
Apply the epoxy to the wing root
12. Mix 1/2oz. (14.5ml) of 30-minute epoxy and
apply to the wing root rib and inside the joiner cavity of the second wing half.
Join the wing halves
13. Assemble the two wing halves with the tightest
seam possible. No gaps should be showing between
the two wing halves. Clean the excess epoxy from the outside of the wing using a paper towel dampened with rubbing alcohol.
Tape the wing halves together
14. Hold the wing halves in alignment while the
epoxy is curing. Use several strips of masking tape on both sides to hold the wing halves tightly together. Let the glue cure.
Cut the aileron servo hole
15. Remove the masking tape from the wing. With
the wing lying upside down and the leading edge facing away from you, hold the aileron servo tray onto the bottom of the wing. The front inside edge of the tray should be placed so the notch is 1/16" (1.5mm) behind the wing joiner locator line, drawn earlier, and centered directly over the wing joint. Using a felt-tip pen, trace the inside of the tray. Use a hobby knife with a new blade to carefully cut out the aileron servo hole. Remove enough of the balsa center rib to allow the servo to be inserted, but do not cut through the
top side of the wing or into the wing joiner cavity.

Remove the covering
16. Hold the servo tray over the hole. Trace the
outside of the tray with a felt-tip pen and then remove the tray from the wing. Draw two lines 3/8” from the ends as shown. Carefully remove only the covering within the lines, being careful not to cut into the balsa wing sheeting.
Shape the mounting blocks
17. Locate the aileron servo tray and the two balsa
servo tray mounting blocks (marked earlier) and position them with the marked dihedral line up. Cut or sand the marked angle out of the block. This angled side will be placed against the wing when the servo tray is installed.
Assemble the servo tray
18. Glue the balsa aileron servo blocks onto the
servo tray so that the angled side you just cut is facing away from the plywood tray.
Trial fitting the aileron servo
19. Trial fit the aileron servo into the servo tray and
the hole cut in the bottom side of the wing. Enlarge either hole, if needed, with a hobby knife or a fine toothed file until a proper fit is achieved.
Install the servo tray
20. Mix 1/8oz. (3.5ml) of 6-minute epoxy to glue
the servo tray to the bottom side of the wing. Apply equal amounts of epoxy to the mounting blocks on both ends of the servo tray. Attach the servo tray the bottom of the wing with the servo wire harness notch facing the leading edge of the wing. Allow the epoxy to fully cure before proceeding to the next step.
Page 10

Apply the center tape
21. Starting at the front of the aileron servo tray,
apply the 1/2" (12.5mm) white plastic center tape completely around the wing over the joint. A small amount of pressure should be applied to make a smooth seam.
Check the aileron hinge
22. Gently tug on each of the ailerons at each hinge
location. If any of the hinges are loose, reglue them as described here. First, flex the surface all the way one direction (DO NOT REMOVE THE AILERON). Apply 5 drops of thin CA onto each hinge. Use a paper towel to absorb the excess glue. Wait a few minutes for the glue to harden, then flex the surface the other direction and glue the other side of the hinges. Finally, flex the back and forth several times to free up the aileron.
Install the aileron control horns
23. Thread the white aileron control horns onto the
torque rods until there is 3/4" (19mm) of torque rod between the wing and control horn.
Assemble the pushrods
24. Locate two plastic clevises and two 8" (203mm)
aileron pushrods. Thread the clevises onto the threaded end of the pushrods until the rod begins to protrude from the inside of the clevis between the forks.

Install the pushrods
25. Attach the control rods to the aileron control
horns. Press the forks of the clevis together until they snap into place.
Aileron pushrods installed
26. Locate the 1/4" (6.5mm) diameter clear
retaining tube and cut two 1/4" (6.5mm) pieces. Slide one piece on each of the two clevises to secure the connection between the clevis and the horn.
This concludes the wing assembly for now. Tape the pushrods to the wing to keep them in place until you install the servo.

Fuselage Assembly
Locate the wing dowel holes
1. Locate the four round holes, two on each side of
the fuselage, and remove the covering over each hole.
Caution: Do not cut out the rectangular holes in the side of the fuselage.
Install the wing dowels
2. Insert both dowels so that they protrude an
equal amount on both sides. Mix 1/4oz. of 30-minute epoxy. Apply glue around the dowels next to the fuselage and rotate them in and out to help force the glue into the holes. Using a paper towel, wipe the excess glue around the ends of the dowels. This will fuelproof and add strength to the wood. From the inside of the fuselage, apply more glue around the dowels where they meet the sides. These wing dowels along with rubber bands will be used to hold the wing in place.
Locate the stab slot
3. Locate the horizontal stabilizer slot under the
covering on the tail section of the fuselage by pressing lightly with your finger. The slot will be located on both sides of the tail. Using a hobby knife, carefully remove the covering, exposing the slots. NOTE: Do
not cut into the wood around the slot.
Install the plywood stabilizer mount
4. Locate the 1/8" (3mm) triangular plywood
stabilizer mounting plate and trial fit it into the bottom of the horizontal stabilizer slot. Lightly sand the plate if necessary to obtain a good fit.
Glue the mount in place
5. Mix 1/8oz. (3.5ml) of 30-minute epoxy. Using a
mixing stick, apply a generous amount of glue into the slot and position the stabilizer mounting plate, pressing it firmly into position. Remove any excess epoxy that remains on the top of the stabilizer mount and on the outside of the fuselage.
Page 13
13
Remove the tail post
6. Located at the rear of the fuselage, behind the
horizontal stabilizer slot, are the balsa tail posts. These posts were left for manufacturing alignment. The posts must be removed in order to insert the horizontal stabilizer. Using a sharp hobby knife, cut the posts even with the slot as shown in the picture.
Locate the vertical fin slot
7. Using your finger, locate the vertical stabilizer
slot on the top of the fuselage. Remove the covering with a hobby knife.
Check the rudder and elevator hinges
8. Gently tug on the rudder and elevator at each
hinge location. If any of the hinges are loose, reglue them as described here: First, flex the surface all the way one direction (DO NOT REMOVE THE SURFACE). Apply 5 drops of thin CA onto each hinge. Use a paper towel to absorb the excess glue. Wait for a few minutes for the glue to harden, then flex the surface the other direction and glue the other side of the hinges. Finally, flex the surface back and forth several times to free it up.
Mark the centerline
9. Locate the horizontal stabilizer. Measure and
mark the exact center on the top surface and of the trailing edge, in the hinge gap, as shown (DO NOT MARK ON THE ELEVATOR).
Align the stabilizer with the wing
10. Insert the stabilizer into the horizontal
stabilizer slot so it is centered in the fuselage. Place the wing onto the fuselage and view the plane from the rear. The stab should be parallel with the wing. If not, sand the stabilizer mounting plate a little at a time until correct.
Page 14
14
Align the stabilizer with the fuse
11. Attach a piece of string with a pin to the center
of the fuselage as shown. Hold the string to the corner of the horizontal stabilizer. The distance from the pin to the horizontal stabilizer must be exactly the same on both sides.
Mark the stab location
12. Using a felt-tip pen, trace a line around the tail
of the airplane on the top and bottom of the horizontal stabilizer.
Remove the center covering
13. Remove the stabilizer and draw two additional
lines, on the top and bottom, 1/16” inside the lines drawn in the last step. Next, carefully cut through the covering at the inside lines and remove the covering
from the center. Do not cut the wood under the
covering! This would seriously weaken the stab and could easily cause the stab to break in flight. If the
stab breaks the plane may crash, so be very careful when you make this cut.
Install the stabilizer
14. Mix 1/4oz. (7.5ml) of 30-minute epoxy. Using a
mixing stick, place glue inside the horizontal stabilizer slot on all sides including the horizontal stabilizer mount. Insert the stabilizer from the rear, and adjust the alignment. Wipe off any epoxy that squeezes out using a paper towel dampened with rubbing alcohol. Set the fuselage aside until the glue cures.
Install the vertical fin
15. Trial fit the fin into the slot in the top of the
fuselage. Using a felt tip pen, trace a line around the front of the fin onto the fuselage. Remove the fin. Next, using a hobby knife, carefully remove the covering from where the fin will sit on the fuselage. Be careful not to cut into the wood.
Mix 1/4oz. (7.5ml) of 30-minute epoxy. Using a mixing stick, apply epoxy to the top of the horizontal stab through the slot. Apply epoxy to the sides and bottom surfaces of the fin base that have balsa wood exposed. Insert the fin into the slot, making sure the fin base is seated firmly on the horizontal stabilizer. Check for a perpendicular angle between the fin and the stabilizer when viewing from the rear. Check this alignment several times as the glue cures.

Locations of the control horns
16. Notice the locations and alignment of the
control horns in both the photo and the illustration before marking and drilling. The rudder control horn must be on the left side. The elevator horn must be underneath and on the right side.
The control horns should be positioned so the holes are lined up with the hinge line as shown in the sketch.
Attaching the rudder control horn
17. Position a control horn as shown in the
previous step, 7/8" (22 mm) from the bottom of the rudder. Mark the two holes with a felt-tip pen.
Attach the control horn
18. Drill two 3/32” (2.4 mm) holes straight through
the balsa rudder at the marks. Place a drop of thin CA
into each hole. This will add strength to the balsa. Redrill the holes to remove any excess glue. Insert two 2 x 20mm machine screws through the control horn, rudder and finally screwing them into the control horn back plate on the opposite side of the rudder. Tighten the screws but do not crush the balsa. Cut off the excess threads that stick out using a wire cutter.
Install the elevator horn
19. Attach the elevator control horn in the same
manner as the rudder. Place the control horn on the bottom side of the elevator 1-1/8” (28mm) away from the fuselage side (see previous photo at earlier step). Mark the two holes with a felt-tip pen. Drill two 3/32” (1.6mm) holes straight through the balsa elevator at the marks. Place a drop of thin CA into each hole. Redrill the holes to remove any excess glue. Thread two 2 x 20mm machine screws through the control horn, elevator and finally into the control horn back plate on the opposite side. Tighten the screws but do not crush the balsa. Cut off the excess threads.
Locate the rudder exit hole
20. The rudder pushrod exit is located on top of the
fuselage on the same side as the rudder control horn. Locate the exit hole using the measurements on the sketch. Cut out the exit using a hobby knife.

Cut the elevator exit hole
21. The precut elevator pushrod exit hole is located
on the same side of the fuselage as the elevator control horn. Locate the exit hole by gently running your finger along the side of the fuselage over the covering. It should be located approximately 7/8” in front of the stab where shown. Using a hobby knife, remove the covering from the elevator pushrod exit slot.
Locate the landing gear channel
22. On the bottom of the fuselage, there is a
channel for the main landing gear. Locate this channel by running your finger over the covering on the bottom of the fuselage. Using a hobby knife remove the covering from this channel.
Prepare the channel for the gear
23. Trial fit the wire landing gear struts into the
holes. If they will not go in easily, drill out the two
holes using a 13/64” drill bit. Next, bevel the inside corners of the holes so that the bend in the wire will seat fully into the holes.
Install the landing gear struts
24. Position the two wire struts in the holes inside
the channel. Center the two metal landing gear straps over the struts so they are approximately 1/2” from the sides of the fuselage. Mark the holes using a felt­tip pen.
Drill the fuselage
25. Drill four holes using a 1/16" (1.6 mm) drill bit.
Mount the struts
26. Using four 2.5 x 10mm self–tapping screws,
fasten the landing gear straps to the bottom of the fuselage over the struts.
Page 17
Prepare the engine mount
27. Carefully trim off the molding braces from both
halves of the nylon adjustable engine mount. Attach the two halves together and onto the firewall using four 6-32 x 7/8” machine screws. Do not tighten the screws completely at this time.
Install the throttle guide tube
28. Roughen the outside of both plastic guide tubes
and clean with a paper towel dampened with rubbing alcohol. This will help the glue stick to the tubes. Install one of the tubes into the upper hole in the firewall. Position the tube so that approximately 2” protrudes out of the firewall. Mix 1/8oz. of 6-minute epoxy and glue the guide tube into the hole in the firewall and into the upper right slot inside the fuselage as shown.
Drill the steering pushrod exit hole
29. Drill a 5/32” hole into the firewall, 3/8” from
the bottom and 5/8” from the inside edge of the fuselage side.
Install the steering guide tube
30. Slide the remaining guide tube into the hole
you just drilled so that 1/2” protrudes. Mix up 1/8oz. of 6-minute epoxy. Glue the tube into the hole and into the lower left slot inside the fuselage. Once the glue has cured, trim off this tube so it is flush with the firewall (Do not trim off the throttle tube).
Make “Z” bends on the wire
31. Make a Z-bend at one end of both of the 1/16” x
19-3/4” wire throttle and steering pushrods. NOTE: Hobbico offers pliers that easily make perfect Z-bends (HCAR2000) see your hobby dealer.
Trim the steering arm
32. Locate the black plastic steering arm. Hold the
arm in your hand so that the screw hole on the side is facing you. Using a wire cutter, remove the left side of the arm. It is not needed.
Install the steering wire
33. Attach the “Z” bend of one of the wires into the
outside hole of the black plastic steering arm. Slide the wire into the lower guide tube so that the steering arm is against the firewall with the screw hole facing forward.

Install the nose gear strut
34. Install the nose gear strut through the steering
arm followed by a 4mm collar. Next, slide the strut through the first engine mount lug and insert a second 4mm collar onto the strut between the lugs. Insert the nose gear strut into the top lug so that the coil is 1/8” below the fuselage bottom. Tighten the wheel collars to the strut using two 3mm x 5mm screws so both collars are against the lower lug of the engine mount.
Position the steering arm
35. Rotate the nose gear strut so that the wheel
(once installed) will point straight ahead. Swing the steering arm so it is approximately 1/2” the from the firewall. Tighten the arm to the strut using a 3mm x 8mm screw. NOTE: The steering arm will stay in place better if a small flat is filed into the strut. This should be done after you have established the proper positioning of the arm.
Assemble the fuel tank plug
36. Push one long and one short aluminum tube
through the black rubber stopper. (The third
aluminum tube will not be used.) Place the two white plastic discs over the tubes. The larger disc should go towards the outside. The nub on the small disc should face away from the rubber stopper. Insert the 3 x 18mm self tapping screw through the larger disc, rubber plug and then into the smaller disc. Do not tighten the screw at this time.
Bend the vent tube
37. Bend the longer tube up as shown so that it will
come within 1/16” from touching the top of the tank when installed. Use your fingers to bend the tube, being careful not to kink it closed.
Install the clunk onto the cap
38. Locate the metal fuel pick-up weight (often
referred to as the “clunk”) and the fuel tubing. Cut the fuel tubing so it is only 5-1/2” long. Attach the fuel tubing to the short aluminum tube and to the clunk.
Install the stopper
39. The stopper assembly can now be inserted into
the tank. The pressure tube should be adjusted so the tube is pointed straight up just under the top of the tank. The rubber stopper must seat over the lip of the tank. Make sure that the tubes are positioned side to
18
Page 19
side. Tighten the stopper by turning the self tapping screw. Do not over-tighten the screw or you may strip out the plastic disc.
Install the foam collar and bend the tubes
40. Locate the black foam collar. Remove the inner
foam circle and place the collar around the neck of the fuel tank. Bend the aluminum tubes outward slightly (1/8”) to allow clearance for the nose gear strut once installed.
Install the tank
41. With the vent tube (inside the tank) pointing
up, insert the fuel tank into the fuselage. Make sure the foam collar is seated well against the firewall.
Brace the fuel tank
42. Hold the tank in position using a small piece of
scrap balsa wood glued to the bulkhead with thin CA.
Adjust the engine mount
43. Remove the needle valve from the engine (if
necessary) and set the engine onto the mount. Adjust the rails until they fit close to the engine case. Remove
the engine and tighten the four screws to secure the mount to the firewall.
Align the engine with the fuselage
44. Position the engine on the mount so that the
face of the engine thrust washer is 1/4” forward of the fuselage sides. Align the engine so that the crankshaft is pointing straight forward. Mark the rails at the four mounting hole locations on the engine using a 5/32” drill bit (or a bit that fits your engine mounting holes the best) to scribe a mark.
Drill mounting holes
45. Remove the engine from the mount and drill
four 3/32” holes at the marks you just made.
Attach fuel tubing to the tank
46. Cut two 6” pieces of medium fuel tubing (not
included). Attach one piece onto each of the aluminum tubes coming from the fuel tank.
Install the throttle pushrod
47. Attach the the “Z” bend of the the 1/16” x 18”
wire pushrod into the inside hole of the carburetor control arm.
19
Page 20
Mount the engine
48. Slide the throttle pushrod wire into the guide
tube and position the engine on the mount. Fasten the engine to the mount using the four 3 x 15mm self tapping screws.
Install the needle valve
49. Line up the needle valve with the engine. Trim
away part of the fuselage side so that there will be plenty of clearance to grip the valve with your fingers. Coat the exposed wood with epoxy to seal it from fuel. Install the needle valve into the carburetor.
Install the muffler
50. Install the muffler onto the engine using the
screws that came with the engine. Attach the fuel tubing from the “vent” in the fuel tank to the muffler pressure tap. Attach the tubing from the “clunk” in the fuel tank to the carburetor. NOTE: You may wish
to shorten the fuel lines for a more direct routing. Make sure that the lines do not get any kinks which could restrict fuel flow.
Attach the propeller to the engine
51. Ream out the spinner backplate to fit on the
engine. Install the spinner backplate, prop, prop washer, and the prop nut onto the engine. Position the prop so it is horizontal when the engine is against its compression (the point at which you feel resistance when you turn the crankshaft counter­clockwise). This is a good habit to get into when installing props onto model airplanes. If the engine quits during flight, the prop will stop horizontally, therefore reducing the chance of prop breakage if you are forced to land on rough terrain. Use an adjustable wrench (not a pliers) to fully tighten the prop nut.
Install the spinner
52. Trim the spinner cone slots so that there is at
least a 1/16” gap between the cone and the prop. Once satisfied with the fit, attach the cone with the screws provided. Be careful not to over-tighten these screws. They are threaded into plastic which can strip out easily if they are over–tightened.
Prepare the servos
53. Install the rubber grommets and bushings,
included with your radio system, onto the four servos. Refer to your radio manual for proper installation of these items.
20
Page 21
Trial fit the servos
54. Trial fit your servos into the plywood servo tray.
Enlarge the servo tray opening, if needed, using a flat file. The servo should fit easily into the radio tray.
Install the servo tray support
55. Position the servo tray support into the fuselage directly in front of the the landing gear block. Glue in place with thick CA.
Install the servo tray
56. Position the servo tray into the fuselage so that
the small rectangular hole is facing forward. You may need to sand the edges and corners slightly for a good fit. Glue in place using thick CA.
Install the servos in the fuselage
57. Routing the wire servo leads forward, install the
servos into the tray using the screws included with the radio system. Do not over-tighten the screws. They should only be snug. Anything tighter will crush the grommets and allow the normal vibrations from the engine to affect the servos. Choose and trim the servo arms so they look similar to the ones shown in the photo.
Install the aileron servo
58. Install the remaining servo into the servo
mount in the wing. Route the leads between the tray and the bottom of the wing as shown.
21
Page 22
Receiver and battery installation
59. Following the radio system’s instruction
manual, plug the three servos into the receiver. Next, plug a servo extension into the aileron channel (usually channel one) of the receiver. Finally, plug the switch into the receiver. Wrap the receiver and battery pack in foam rubber using rubber bands or masking tape to hold the foam in place. Install the battery and receiver into the fuselage. The battery should be located directly behind the fuel tank. The receiver should then be placed directly behind the battery. Secure these components in place using a couple of pieces of scrap wood (popsicle sticks work well).
Mount the switch to the fuselage
60. Cut out the opening on the left side of the
fuselage for the switch and install using the screws included with the switch. We recommend using a Great Planes Switch/Charge jack. This makes it easy and convenient for charging your receiver batteries.
Prepare the pushrods
61. Locate the two wooden dowel pushrods and
apply thin CA to the ends of the shrink tubing on both rods.
Install the pushrods
62. Insert the two pushrods, threaded end first,
through the fuselage and out the two pushrod exits at the back of the fuselage. You may have to bend the rods slightly to eliminate binding.
Make the clevis retainers
63. Cut two 1/4” wide pieces of the clear tube. Slide
one on each of the pushrods that protrude out of the fuselage.
Install the two clevises
64. Screw a clevis onto each pushrod until the
threads protrude about 1/16” between the clevis forks.
22
Page 23
Attach the pushrods
65. Attach the two clevises to the control horns.
Use the 2nd hole from the outside. Check to make certain that the pushrods do not bind in the openings and that they operate smoothly. Slide the clevis retainer over the clevis forks.
Center the servos with your radio
66. Turn on the transmitter and then the receiver
switch. Center all of the trim levers and place the throttle stick at its midway position. Turn off the receiver switch and then the transmitter. By doing this, your servos will be at their centered (neutral) position when you connect the pushrods. Refer to the following photos and replace or trim the servo arms as shown. To do this, simply remove the servo arms and reposition them on the splined servo output shaft. Be
sure to reinstall the screws.
Mark the pushrods
67. Holding the elevator in its neutral position,
mark the pushrod wire where it crosses the servo arm as shown. Next, hold the rudder at its neutral position and mark the wire the same way.
Cut the pushrods
68. Cut off the pushrods approximately 3/8” past
the marks.
Connect the pushrods
69. Make a “Z” bend at each mark. Remove the
servo arms from the servos. Attach the rods to the servo arms. You may need to enlarge the holes slightly on the arms. A 5/64” drill bit works great for this. Reattach the servo arms in the same position.
Attach the pushrod connector
70. Remove the servo arm and install a pushrod
connector on the opposite side of the rudder pushrod. This will be for the steering rod. Thread the nut onto the connector. The connector must be able to rotate in the servo arm, so do not over–tighten the nut. Place a drop of thin CA onto the threads to lock the nut in
23
Page 24
place, thread the 3mm x 4mm screw into the connector.
Install the steering pushrod
71. Slide the wire steering pushrod into the
pushrod connector. Straighten the nose gear and tighten the pushrod connector. Using a wire cutter, carefully remove the excess wire, leaving only about 3/4” remaining past the connector.
Connect the throttle servo
72. Install the second pushrod connector onto the
throttle servo arm. Slide the throttle pushrod wire through the connector. Hand tighten this screw so that the carburetor is half open. Final throttle adjustment will be made later. Using a wire cutter, carefully remove the excess wire, leaving only about 3/4” remaining past the connector.
Connect the aileron servo
73. Hold the ailerons at neutral and mark the
servo wheel where the rods intersect (see sketch). Note the wires are intentionally positioned off center
to cause the aileron to travel further up than down, which is known as “differential aileron throw.” This will give smoother banking control and will reduce the airplanes adverse yaw tendency (typical with flat bottom wings). Make a “Z” bend at the mark on each wire and connect to the servo wheel. You will have to remove the wheel to connect the rods. Enlarge the holes if needed using a 5/64” drill bit.
Straighten the antenna
74. Unwind the antenna and
straighten (do not stretch) the wire to its full length. Do not cut the antenna wire as this will decrease the range and sensitivity of your receiver.
Drill an antenna exit
75. Using a 3/16” drill bit, drill a hole centered
approximately 3/4” behind the wing saddle on top of the fuselage. Cut a 3/8” long piece of medium fuel tubing and center it inside this hole.
Securing the antenna
76. Route the antenna away from the servos and up
through the antenna exit. Use a trimmed servo arm and rubber band at the end of the antenna to a pin pushed in the top of the stab.
24
Page 25
Install the wheels
76. Place one wheel collar on each strut, followed
by a wheel. Secure each wheel with an additional wheel collar, making a total of two on each strut--one on the inside and one on the outside of the wheel. The nose gear wire is thinner, so use the wheel with the smaller center hole along with the two remaining small wheel collars. The wheels must all spin freely and have no tendency to bind.
Attach the Wing
77. Connect the aileron servo to the aileron
extension and attach the wing onto the fuselage using 12 #64 rubber bands. Install 5 on each side first. Then criss-cross the remaining 2. This will hold the wing securely, but will allow it to pop off in the event of a cartwheel on the ground, thus minimizing damage.
Notes on Fuselage assembly:
25
Page 26
1. Turn on the Transmitter and then the Receiver. Standing behind the plane, make the following movements with the transmitter and observe the control surfaces:
If any of the servo movements are opposite, reverse the servo direction with the servo reversing switches on the transmitter.
2. For added safety and convenience, the throttle should be set up so that the engine can be stopped using the throttle trim. To do this, loosen the pushrod connector screw and move the throttle pushrod so that the carburetor is completely closed with the throttle stick and trim lever on the transmitter fully back. (NOTE: If the carburetor does not fully close, adjust the idle stop screw on the carburetor until it will.) Next, tighten the screw on the pushrod connector. Test the trim lever by advancing it to full. This will be a fast idle position with the carburetor barrel slightly open (about 1/32”). See sketch. Now move the throttle stick forward to full. Make sure that the carburetor barrel opens all the way. See sketch. If it doesn’t open far enough or opens too far (bending the rod) move the pushrod connector in or out on the servo arm and/or the carburetor arm to gain or reduce movement. The throw will be correct when the carburetor barrel will
stop fully open at the same time the throttle stick reaches full. With the throttle set up properly, you should be able to start and run the engine with the trim lever set midway to full position (adjusted for a smooth but slow idle). Then when it is time to stop the engine, simply pull back the trim to close the carburetor and the engine will stop running.
3. Check the movement of the control surfaces. Use a ruler to match our measurements listed below. If your radio features dual rates, set up both the high and the low rates following the radio system’s instructions. If your radio does not have dual rates, set up the plane using the low rates first and increase the throws as you get familiar with the plane.
Low rate High rate
Aileron 3/8” up 1/2” up
1/4” down 3/8” down
Elevator 5/16” each way 7/16” each way
Rudder 5/8” each way 3/4” each way
These are the suggested deflections from center.
If you need more movement, you should move the clevis to a hole closer to the surface or you can install a larger servo wheel and move the rod further out from center. If you have too much movement, do the opposite. See sketches below:

1. Check the lateral balance. With the wing attached, gently lift the airplane by the spinner and the bottom center of the tail. You may need an assistant to help you with this. If one wing tip is noticeably heavy (the tip will drop), attach some weight to the lighter tip until they are equal. Use Great Planes “stick-on” lead weights (GPMQ4485) for easy balancing.
NOTE: This section is VERY important and must not be omitted! A model that is not properly balanced will
be unstable and possibly unflyable.
2. Check the fore-aft balance point, also referred to as the “center of gravity” (CG). Accurately mark the balance point on the bottom of the wing of both sides of the fuselage. The balance point is located 3-7/8” back from the leading edge. This is the balance point at which your model should balance for your first flights. Later, you may wish to experiment by shifting the balance up to 1/4” forward or back to change the flying characteristics. Moving the balance forward may improve the smoothness and arrow-like tracking, but it may then require more speed for takeoff and make it more difficult to slow down for landing. Moving the balance aft makes the model more agile with a lighter and snappier “feel.” In any case, please start at the location we recommend and do not at any time balance your model outside of the recommended range of 3-5/8” to 4-1/8” back from the leading edge.
The plane must be “ready to fly” (all components installed) with an empty fuel tank before checking the CG. Place your finger tips on the model at the marked balance point. Lift the model. If the tail drops, the plane is “tail heavy” and you must add weight to the nose. If the nose drops, the plane is
“nose heavy” and you must add weight to the tail. If possible, first attempt to balance the model by changing the position of the battery and receiver. If you are unable to obtain good balance by doing so, then it will be necessary to add weight to the nose or tail to achieve the proper balance point. NOTE: Weight may be easily installed by using stick on lead available from Great Planes (GPMQ4485).

Balance Your Model

There is one thing that you will need to fly your SuperStar 60 safely that is not furnished with the kit: You will need a qualified instructor to teach you to fly. No trainer ever made will let you teach yourself to fly safely. It can be done, but you would be seriously risking more than just the model. To find an instructor, you should join an R/C flying club. If there is not a club nearby, then you should find an experienced model pilot who is willing to help you. The chosen instructor should fly well enough to allow you to concentrate on your own flying. If you are worried about your instructor crashing your model, you will not be able to concentrate on learning to fly. After you have found an instructor, you should spend some time just talking with him about what you will be trying to learn. He should inspect the model to be certain that it is ready to fly. Listen to him and try to gain by his experience.
Now that you have a good model and an instructor whom you trust, you can go out and get started learning to fly. You can expect to be very nervous at first, and you will make some mistakes. There will be several instances where the instructor will prevent you from crashing. This will be unsettling, but the thing to do is jump right back into flying the model (after your knees stop shaking, of course). This is one of the most important things about learning to fly model airplanes...you have to fly! Fly as often as you can. Be sure to make several flights each time you go to the flying field, but give yourself time after each flight to calm down and discuss the flight with your instructor. Spending some time after each flight talking about what happened and what you need to work on to improve your skills will pay off with greater confidence in your own growing abilities.
CHARGE THE BATTERIES
Follow the battery charging procedures in your radio instruction manual. You should always charge your transmitter and receiver batteries the night before you go flying, and at other times as recommended by the radio manufacturer.
FIND A SAFE PLACE TO FLY
1. The best place to fly your R/C model is an AMA (Academy of Model Aeronautics) chartered club field. Ask your hobby shop dealer if there is such a club in
your area and join. Club fields are set up for R/C flying which makes your outing safer and more enjoyable. The AMA can also tell you the name of a club in your area. We recommend that you join the AMA and a local club so you can have a safe place to fly and also have insurance to cover you in case of a flying accident. (The AMA address is listed at the front of this instruction book).
If there is not a flying club in your area, you need to find a large area, free of obstructions, with a smooth surface that can be used as a runway, and located at least 6 miles away from any other R/C airplane operation and away from houses, buildings and streets. A schoolyard may look inviting but it is too close to people, power lines and possible radio interference.
GROUND CHECK THE MODEL
If you are not thoroughly familiar with the operation of R/C models, ask an experienced modeler to check to see that you have the radio installed correctly and that all the control surfaces do what they are supposed to. The engine operation must also be checked and the engine “broken in” on the ground by running the engine for at least two tanks of fuel.
Follow the engine manufacturer’s recommendations for break-in. Check to make sure all screws remain
tight, that the hinges are secure and that the prop is on tight.
RANGE CHECK YOUR RADIO
Check the operation of the radio before every time you fly. This means that with the transmitter antenna collapsed and the receiver and transmitter on, you should be able to walk at least 100 feet away from the model and still have control. Have someone help you. Have them stand by your model and, while you work the controls, tell you what the various control surfaces are doing.
Repeat this test with the engine running at various speeds with an assistant holding the model. If the control surfaces are not acting correctly at all times, do not fly! Find and correct the problem first.

ENGINE SAFETY PRECAUTIONS
NOTE: Failure to follow these safety precautions may result in severe injury to yourself and others.
Keep all engine fuel in a safe place, away from high heat, sparks or flames, as fuel is very flammable. Do not smoke near the engine or fuel; remember that the engine exhaust gives off a great deal of deadly carbon monoxide. Therefore do not run the engine in a closed room or garage.
Get help from an experienced pilot when learning to operate engines.
Use safety glasses when starting or running engines.
Do not run the engine in an area of loose gravel or sand, as the propeller may throw such material in your face or eyes.
Keep your face and body as well as all spectators away from the plane of rotation of the propeller as you start and run the engine.
Keep items such as these away from the prop: loose clothing, shirt sleeves, ties, scarfs, long hair or loose objects (pencils, screw drivers) that may fall out of shirt or jacket pockets into the prop.
Use a “chicken stick” device or electric starter; follow instructions supplied with the starter or stick. Make certain that the glow plug clip or connector is secure so that it will not pop off or otherwise get into the running propeller.
Make all engine adjustments from behind the rotating propeller.
The engine gets hot! Do not touch it during or after operation. Make sure fuel lines are in good condition .
To stop the engine, cut off the fuel supply by pinching the fuel line. Do not use hands, fingers or any body part to try to stop the engine. Do not put anything into the prop of a running engine.
AMA SAFETY CODE
Read and abide by the Academy of Model Aeronautics Official Safety Code, a portion of which is reprinted here:
GENERAL
1. I will not fly my model aircraft in sanctioned events, air shows, or model flying demonstrations until it has been proven to be airworthy by having been previously successfully flight tested.
2. I will not fly my model aircraft higher than approximately 400 feet within 3 miles of an airport
without notifying the airport operator. I will give right-of-way and avoid flying in the proximity of full­scale aircraft. Where necessary, an observer shall be utilized to supervise flying to avoid having models fly in the proximity of full-scale aircraft.
3. Where established, I will abide by the safety rules for the flying site I use, and I will not willfully and deliberately fly my models in a careless, reckless and/or dangerous manner.
6. I will not fly my model unless it is identified with my name and address or AMA number, on or in the model.
8. I will not operate models with pyrotechnics (any device that explodes, burns, or propels a projectile of any kind) . . .
RADIO CONTROL
1. I will have completed a successful radio equipment ground range check before the first flight of a new or repaired model.
2. I will not fly my model aircraft in the presence of spectators until I become a qualified flyer, unless assisted by an experienced helper.
3. I will perform my initial turn after takeoff away from the pit or spectator areas, and I will not thereafter fly over pit or spectator areas unless beyond my control.
4. I will operate my model using only radio control frequencies currently allowed by the Federal Communications Commission. . .

It is best if you let the instructor test fly the model first. Once he has flown the model he will adjust the trim to eliminate any turning, climbing, or diving tendencies that he found on the test flight. This will help make your first flights much easier and safer.
Ground Handling:
Start with learning to steer the model on the ground using the rudder and throttle. You should learn to guide the airplane on the ground at various speeds and directions.
Be careful– you do not have brakes, so do not get close to any obstacles.
Takeoff:
Line up as straight into the wind as possible. Gradually advance the throttle to get the model rolling. Advance the throttle to full. Using small rudder inputs, guide the plane straight down the runway. Let the plane get up to flying speed on the ground before lifting off. Once up to speed, lift off by smoothly applying a little up elevator and climb out gradually. Do not try to gain altitude or turn until the airplane gains additional speed.
Flying:
We recommend that you take it easy with your SuperStar 60 for the first several flights and gradually “get acquainted” with the airplane as your engine gets fully broken–in. As you will see, this airplane is smooth and very predictable. Your confidence will grow to the point that flying is more fun than ever. Just remember to take your time. Follow your instructor’s advice and learn to control the model in the many basic maneuvers possible with this model.
Landing:
When it’s time to land, do a couple of slow flybys (again, straight into the wind) at a safe altitude and get familiar with the plane’s slow flying characteristics. Landings will involve learning to judge the height, position, direction, and speed of the model in relation to the runway. You should not attempt to land the model yourself until you are comfortable flying the model in the air. Landing is the most difficult maneuver for beginners so it should only be practiced after you can fly confidently.
As with takeoffs, always land into the wind. Line­up with the runway and reduce the throttle to idle. Glide the model down using ailerons to keep the wings level and elevator to control altitude. Be careful not to use too much elevator at slower speeds. This could cause the airplane to stall too close to the
ground. If the airplane is coming in short, increase the throttle to get to the runway. If you come in too long, raise the throttle slowly and abort the landing. Do not force the plane to land. Try again with a slightly lower approach. Just before touchdown, add in a little more elevator to flare the airplane for a smooth touchdown. Perfect landings are difficult so practice them often.
Thank you for choosing the SuperStar 60. We hope that it will be only the first of many, in a lifetime enjoyment of radio control airplanes.

Ailerons – Hinged control sur-
faces located on the trailing edge of the wing, one on each side, which provide control of the airplane about the roll axis. The control direction is often confusing to first time model­ers. For a right roll or turn, the right hand aileron is moved upward and the left hand aileron downward and vice versa for a left roll or turn.
Canard – A unique type of air­plane, in which the wing is located near the back of the fuselage and the horizontal sta- bilizer is located at the nose of the fuselage.
Carburetor – The part of the engine which controls the speed or throttle setting and lean/rich mixture via setting of the needle valve.
Charge Jack – The plug recepti­cal of the switch harness which
the charger is plugged into to charge the airborne battery. An
expanded scale voltmeter (ESV) can also be plugged into
it to monitor battery voltage during a flying session. It is advisable to mount the charge jack in an accessible area of the fuselage so an ESV can be used without removing the wing.
Charger – Device used to recharge batteries and is usual­ly supplied with the radio if
NiCd batteries are included.
Chicken Stick – A hand held
stick used to flip start a model airplane engine.
Clunk – A weighted fuel pick up used in a fuel tank to assure the intake line is always in fuel.
Clevis – A small clip which is threaded or soldered onto the wire end of a pushrod and con­nects the pushrod to the
control horn of a control sur­face. The threads allow fine adjustment of length of the pushrod.
Computer Radio – A radio con­trol unit in which the transmit- ter has several advanced func­tions which can be pro­grammed completely to fine tune an airplane without mak­ing mechanical changes.
Control Horn – The arm which is attached to a control surface at the hingeline and is connect­ed to a pushrod.
Dead Stick – A term used to describe unpowered flight (glide) when the engine quits running.
Delta Wing – An airplane with a triangle shaped wing. Delta wings have no horizontal stabi-
lizer.

Words shown in italics are defined elsewhere in this glossary.
Page 32
Dihedral – The V shaped bend in the wing. Typically more dihedral causes more aerody­namic stability in an airplane, and causes the rudder to con­trol both the roll and yaw axis. This is why some trainers and sailplanes require only 3 chan­nels of radio control—i.e., hav­ing no ailerons.
Electric Starter – A hand held, electric motor used for starting a model airplane engine.
Elevator – Hinged control sur­face located at the trailing edge of the horizontal stabilizer, which provides control of the airplane about the pitch axis and causes the airplane to climb or dive. The correct direc­tion of control is to pull the transmitter elevator control stick back, toward the bottom of the transmitter, to move the elevator upward, which causes the airplane to climb and vice versa to dive.
Elevon – Control surfaces used on a flying wing or Delta wing type airplanes, located at the trailing edge of the wing like ailerons. Elevons move both up or down together to control the pitch axis like an elevator, and move differentially to control the roll axis like ailerons. Elevons require either a mechanical or electronic chan­nel mixer.
Engine – The source of thrust of an airplane.
Expanded Scale Voltmeter (ESV)
- Device used to read the battery voltage of the on board battery pack or transmitter battery pack.
Flaps – Hinged control surface located at the trailing edge of the wing inboard of the ailerons. The flaps are lowered to produce more aerodynamic lift from the wing, allowing a slower takeoff and landing speed. Maneuvering flaps move up and down in con­junction with the elevator, and enhance the pitch control of the airplane. This is used on some aerobatic type of models, and requires a mechanical or elec­tronics channel mixer. Note: Flaps and Maneuvering Flaps are advanced features and are not necessary or recommended on trainer aircraft.
Flaperon – Control Surfaces on a standard type airplane, located at the trailing edge of the wing, which function as ailerons by moving differentially, and as flaps by moving up or down together. Flaperons require either a mechanical or electronic channel mixer. Note: Flaperons are an advanced feature and are not recommended on trainer
aircraft.
Flight Box – A special box used
to hold and transport all equip­ment used at the flying field.
Flight Pack – or Airborne pack. All of the radio equipment installed in the airplane, i.e.,
Receiver, Servos, Battery, Switch harness.
Foam Rubber – A soft foam
material used to wrap the receiver and airborne battery for vibration dampening in the airplane.
Fuel Over Flow Line (Vent) – The fuel line which is either open to
atmospheric pressure or attaches to the muffler pressure nipple, to pressurize the fuel tank for bet­ter fuel flow to the engine. This is the line through which the fuel will overflow when the tank is full.
Fuel Pick Up Line – The fuel line in the fuel tank through which the fuel travels to the carburetor. Typically a flexible tube with a weight or "Clunk" on the end which allows it to fol­low the fuel with changes in air­craft altitude. This is the line through which the tank is filled.
Fuel Tank – The container which holds the fuel in an air­plane.
Fuselage – The body of an air­plane
Fun Fly Airplane – A specialty model designed to be very light­weight and perform very tight, rapid, maneuvers such as loops and rolls.
Glow Plug Clip/Battery – A 1.2 volt battery, which is connected to the glow plug on a model air­plane engine for starting. The battery is removed once the engine is running steadily.
High Wing – An airplane with the wing mounted on top of the
fuselage.
Hinge – A flexible or hinged blade
which is glued into a control sur­face and trailing edge to allow con­trol surface deflection or move­ment. Note: It is extremely impor­tant that all hinges are permanent­ly glued into both the control sur­face and trailing edge. Improper gluing will cause a crash.

Horizontal Stabilizer – The hor­izontal tail surface at the back of the fuselage which provides aerodynamic pitch stability and control to the airplane.
Low Wing – An airplane with the wing mounted on the bot­tom of the fuselage.
Main Landing Gear – The land­ing gear and wheels which are usually on the bottom of the fuselage under the wing on a high wing airplane, or on the bottom of the wing on a low wing airplane.
Mid Wing – An airplane with the wing mounted in the center of the fuselage, between the top and bottom.
Muffler – A device attached to the exhaust stack of the engine to reduce noise, and increase back pressure which helps low speed performance. Note: Most R/C Clubs require the use of mufflers.
Needle Valve – Adjustment on a carburetor used to set proper
fuel mixture. Some carburetors have separate needle adjust­ments for low and high throttle. Typically turning the needle clockwise (screwing in) leans the mixture and vice versa. However, there are a few excep­tions—refer to the engine man­ufacturer’s instructions.
NiCd – Nickel Cadmium bat­tery. Rechargeable batteries which are typically used as power for radio control trans-
mitters and receivers.
Nitro – NitroMethane, a fuel
additive which increases a model airplanes’ ability to idle low and improves high speed performance. Ideal nitro con­tent varies from engine to engine. Refer to the engine manufacturers’ instructions for best results. Nitro content in fuel is indicated by the percent of the fuel.
Nose Gear – The landing gear at the nose of the airplane if the airplane is a Tricycle landing gear type. Typically connected to the rudder servo for ground steering.
Pattern Airplane – A model air­plane designed to perform pre­cision aerobatics.
Pitch Axis – The airplane axis controlled by the elevator. Pitch is illustrated by holding the air­plane at each wingtip. Raising or lowering the nose is the pitch movement. This is how the climb or dive is controlled.
Pushrod-A rigid piece of wood, fiberglass, nylon or steel used to transfer movement from a servo to a control surface or throttle.
Pylon Racing Airplane – A model airplane designed for racing. They are flown around a set course of (3) "Pylons."
Receiver (Rx) – The radio unit in the airplane which receives the transmitter signal and relays the control to the servos. This is somewhat similar to the radio you may have in your family automobile, except the
radio in the airplane perceives commands from the transmit­ter and the radio in your car perceives music from the radio station.
Roll Axis – The airplane axis controlled by the ailerons. Roll is illustrated by holding the air­plane by the nose and tail. Dropping either wingtip is the roll movement. This is used to bank or turn the airplane.
Rudder – Hinged control surface located at the trailing edge of the vertical stabilizer, which pro­vides control of the airplane about the Yaw axis and causes the airplane to Yaw left or right. Left rudder movement causes the airplane to Yaw left and right rudder movement causes it to Yaw right.
Sailplane – An airplane which flies without an engine. Sailplanes are designed to ride on warm, rising air currents, called thermals. Sailplanes are launched by several methods; a giant sling shot called a high start, a winch which pulls the sailplane up like a kite, or with the assistance of a small engine or electric motor.
Servo – The electronic/ mechanical device which moves the control surfaces or throttle of the airplane accord­ing to commands from the receiver. The radio device which does the physical work inside the airplane.
Servo Output Arm – The remov­able arm or wheel which bolts to the output shaft of a servo and

connects to the pushrod.
Spinner – The nose cone which covers the hub of the propeller.
Sport Airplane – A model which possesses some attribut­es of many of the specialty air­planes and are best for general flying as they are the most ver­satile and durable.
Switch Harness – The on/off switch for the flight pack which is mounted in an accessible location on the fuselage.
Tachometer – An optical sen­sor designed specifically to count light impulses through a turning propeller and read out the engine RPM.
Tail Wheel – The wheel at the tail of the airplane on standard landing gear or tail dragger type airplanes. Steering is typi­cally coupled to the rudder for ground handling.
Threaded Horns – Small nylon horns which thread onto the threaded portion of the aileron
torque rods and connect to the clevis of the aileron pushrods.
Torque Rods – Rigid bent wire
rods inserted into ailerons, running along the wing trailing edge and bent down to connect to the aileron servo push rods.
Trainer Airplane – A model designed to be inherently sta­ble and fly at low speeds, to give first time modelers time to think and react as they learn to fly.
Transmitter (Tx) – The hand held radio controller.This is the unit that sends out the com­mands that you input.
Transmitter Modes – Mode I. Left hand stick controls elevator and rudder. Right
hand stick controls throttle and
aileron.
Mode II. Left hand stick con-
trols throttle and rudder. Right hand stick controls elevator and aileron. Mode II is by far the most popular in the United States.
Mode III. Left hand stick con­trols throttle and aileron. Right hand stick controls elevator and rudder.
Single Stick. A special trans­mitter with only one stick. Elevator and aileron are con-
trolled with the stick. Rudder is controlled by twisting the end of the stick. Throttle is con­trolled by a lever on the top or side of the transmitter. Note: Single stick equipment is no longer being produced by most of the radio manufacturers.
V-Tail – An airplane which has two tail surfaces in the shape of a V, in lieu of a vertical stabiliz­er and horizontal stabilizer. The control surfaces on a V-tail are called ruddervators and function both in the same direction as an elevator and in opposite directions as a rudder.
Vertical Stabilizer – The non­moving surface that is perpen­dicular to the horizontal stabi­lizer and provides lateral stabil-
ity. This is the surface the rudder attaches to.
Wheel Collar – A small, round retaining device used to keep wheels from sliding off an axle.
Wing - The main lifting surface of an airplane.
Yaw Axis – The airplane axis controlled by the rudder. Yaw is illustrated by hanging the air­plane level by a wire located at the center of gravity. Left or right movement of the nose is the Yaw movement. Many air­craft are not equipped with ailerons and the roll and Yaw axis are controlled by the rud­der. This is due to the larger amount of dihedral in the wing. This is why most trainer aircraft have a larger amount of dihe­dral.
Z Bend – A simple Z shaped bend in the wire end of a pushrod which is used to attach the pushrod to a servo
output arm.
Z Bend Pliers – An inexpensive
plier type tool used for easily making perfect Z bends.
