IMPORTANT!!! Two of the most impor tant things you can do to preserve the radio controlled aircraft hobby are to avoid fl ying near full-scale aircraft and avoid fl ying near or over groups of people.
PROTECT YOUR MODEL, YOURSELF
& OTHERS… FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
1. Y our Tiger Moth should not be considered a to y , but rather a sophisticated, working model that functions very much like a full-size airplane. Because of its perf ormance capabilities, the Tiger Moth, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage to property.
2. You must assemble the model according to the instructions. Do not alter or modify the model, as doing so may result in an unsafe or unfl yable model.
In a few cases the instructions may differ slightly from the photos. In those instances the written instructions should be considered as correct.
3. You must take time to build straight, true and strong.
4. Y ou must use an R/C radio system that is in good condition, a correctly sized motor, and other components as specifi ed in this instruction manual. All components must be correctly installed so that the model operates correctly on the ground and in the air. You must check the operation of the model and all components before every fl ight.
5. If you are not an experienced pilot or have not fl own this type of model before, we recommend that you get the assistance of an experienced pilot in your R/C club for
your fi rst fl ights. If you’re not a member of a club, your
local hobby shop has information about clubs in your area whose membership includes experienced pilots.
6. While this kit has been fl ight tested to exceed normal use,
if the plane will be used for extremely high stress fl ying, such as aggressive aerobatics, or if a motor larger than one in the recommended range is used, the modeler is responsible for taking steps to reinforce the high stress points and/or substituting hardware more suitable for the increased stress.
We, as the kit manuf acturer, provide y ou with a top quality, thoroughly tested kit and instructions, but ultimately the quality and fl yability of your fi nished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model.
Remember: Take your time and follow the instructions to end up with a well-built model that is straight and true.

ASSEMBLY
Mount the Wings
3. Also cut the skin from both sides of the bottom wing
over the notches f or the outer wing struts. (There is no need to cut the skin from the slots in the top wing.)
1. If you will be fl ying your Tiger Moth aggressively by
fl ying it outdoors in windy conditions or performing aggressive
aerobatics, or if you will be using servos, batteries or a motor larger than those recommended, apply two 6" [150mm] strips of 3/4" [20mm] fi ber-reinforced tape to the bottom of both
wings as shown. (We marked light centerlines on the strips
of tape to make them easier to center.) If you will be fl ying
your Tiger Moth in calm conditions or indoors in a normal,
scale-like manner, no reinforcement is required.
2. Use a sharp hobby knife to cut the skin from the top of
the bottom wing over the holes for the landing gear struts.
4. Cut the C.G. marking template from the back of the
manual. Tape the template to the top of the bottom wing with the front edges of the template aligned with the leading edge. Use a small pin or a sharpened pencil to lightly puncture small dimples through the cross marks in the template into the wing skin. When balancing the plane later, it will be suspended with sharpened pencils or pens “keyed” into the dimples. Note: Should you ever need to re check the balance in the future but have misplaced your template, the recommended balance point is 15/16" [23.8mm] from the leading edge of the bottom wing at the fuselage sides. The forward balance point is 3/4" [19.1mm] and the aft balance point is 1-1/8" [28.6mm].
4
5. Test fi t the bottom wing to the fuselage just to see how
it fi ts. Remov e the wing and apply a bead of thick or medium foam-safe CA to the wing saddle and fi t the wing back into position. Glue the front and back of the wing to the fuselage as well.
Top Wing
7. Test fi t the top wing to the cabanes. View the model
from the bottom, making sure the leading edge of the top wing is parallel with the leading edge of the bottom wing. If necessary, there should be enough free play in the notches to rotate the top wing to get it aligned. If y ou need to move the top wing but cannot, the notches may be slightly enlarged.
8. Once y ou can get the top wing aligned with the bottom
wing, glue it to the cabanes with a small amount of thin, foam-safe CA—using only a little thin CA will allow it to harden faster and keep e xcess from running all ov er the rest of the wing or dripping onto your clothes or workbench!
6. Test fi t the cabanes as shown, making certain they
are all the way down into the “pockets” in the fuselage. View the top edges of the cabanes to make sure they align with each other. Mak e any adjustments necessary . Then, glue the cabanes into position with foam-safe CA.
Refer to this photo for the following two steps.
9. Test fi t the outer struts to the top and bottom wings.
Then, glue the struts to the bottom wings only with a small
amount of thin CA.
10. As when gluing the top wing to the cabanes, view
the model from the bottom. Note the alignment between the leading edge of the top and bottom wing to see if they are parallel with each other. If necessary, adjust the top wing on the struts until the leading edges are parallel. Then, glue the top wing to the struts with a small amount of thin, foam-safe CA.
5
11. After the CA on the struts and cabanes has hardened,
follow with fi llets of J&Z R/C 56 or thick or medium foam-safe CA to all the glue joints of the wings including the bottom wing to the fuselage and both wings to the cabanes and
outer struts.
Mount the Stab and Fin
1. Use a sharp hobby knife to cut the skin from all the
slots and notches in the horizontal stabilizer (stab), elevator
and rudder.
4. Hold the stab to the fuselage and view the model from
the rear to see if it is parallel with the bottom wing. If the stab is not parallel with the bottom wing, lightly sand or trim the high side of the stab saddle to get the stab to align.
5. The same way you glued on the wing, apply thick or
medium foam-safe CA to the stab saddle and then set the stab down into position. Make sure the leading edge of the fi n is centered over the top of the fuselage. Hold the stab in position long enough for the glue to set (or use a light mist of CA accelerator).
2. Make sure the elevator and rudder can move up and
down and left and right freely by fl exing them back and forth a
few times. If the hinge joints seem too rigid, move them back
and forth a few more times to about a 45-degree angle in both
directions. When you do the elevator , align the hinge line with
the edge of your workbench or a cardboard box to keep the
elevator halves aligned.
3. Glue the fi n to the stab, making sure the two are
perpendicular. NOTE: Be certain that the slot for the elevator
horn is on the right side.
Hook Up the Elevator & Rudder
1. Connect both pushrods to the control horns with the
micro FasLink™ connectors as shown.

2. Guide the rudder pushrod up through the rudder tube
in the left side of the fuselage. Then, fi t and glue the rudder
horn into the elevator.

5. If using ES-40 Pico servos, mount a screw-lock
connector to the middle hole of one servo arm and to the inner hole of the other servo arm. If using different servos,
mount the connectors in the holes closest to 5/16" [7.5mm] and 13/32" [10mm] from center.
6. Turn on your transmitter and center the trims. Temporarily
connect the servos to your receiver. Connect the ESC to the receiver and a battery to the ESC so you can power up the system. Mount the servo arms to the servos.

3. Fit and glue the elevator horn into the elevator the
same way.

4. Make two single-arm servo arms by cutting off the
unused arms.
7. Unplug the servos and the ESC from the receiver and
mount the servos to the servo tray in the fuselage with the screws that came with this kit (or with the screws that came with the servos).
7
If necessary, use the servo reversing function in your transmitter to reverse the servos so the elevator, rudder and throttle respond correctly.
Mount the Cowl & Landing Gear
1. Use medium-grit sandpaper to roughen the inner
surfaces of the forward legs on the plywood landing gear struts where they will be glued to the main landing
gear wires.
Refer to these photos for mounting
the receiver, ESC and motor.
8. Reconnect the servos and the ESC to the receiver . Use
the included adhesive-back Velcro or double-sided adhesive
foam tape (not included) to mount the receiver wherever
convenient, such as to the sides or top of the “engine box”
or to the back of the former in the servo compartment where shown. If y ou do mount the receiv er back in the servo
compartment, make sure the pushrods and servo arms don’t
hit the receiver when the servo arms rotate forward.
9. Mount the ESC where shown. Apply a strip of the
rougher, “hook side” of adhesiv e-backed V elcro where shown
for the battery.
10. Mount the motor to the fi rewall with the three included
2mm x 8mm Phillips wood screws. Connect the motor wires
to the ESC and make sure the motor is turning the correct
direction by plugging in the battery and running the motor. If the motor is turning the wrong direction, switch any two
motor/ESC wires with each other.
11. With the radio on and the trims centered, center the
rudder and elevator and tighten down the screws in the
screw-lock connectors to lock the pushrods down. Use the
control sticks on your transmitter to move the elevator and
rudder, making sure they respond in the correct direction.
2. Use a small piece of paper towel or a small cloth
dampened with denatured alcohol or other solvent to wipe any residual oils or contaminants from the landing gear wires. Use medium-grit sandpaper to scuff the gear wire so glue will adhere.
Refer to this photo for the next two steps.
3. Insert the main landing gear wire into the fuselage—
the gear should fi t tightly enough to stay in on its own, but if it doesn’t fi t tightly add a drop of thin, foam-safe CA to the legs where they go into the mounts.
4. One at a time, position the struts to the gear and in
the wing and glue them to the gear wires with thin CA. Hint: before positioning the struts, “prime” them with a light mist of CA accelerator spray ed from a distance of appro ximately 12" [300mm]. This will cause the CA to harden faster, prev enting it from running down onto the rest of the model.
8
5. Once the struts have been glued to the gear wires,
apply a small fi llet of thick or medium CA to the wire and the
struts securely holding them on.
6. Carefully cut a small bevel the bottom corners of the
front fuselage former.
9. Fit the cowl over the fuselage so the cutout for the
propeller adapter will clear the adapter and the prop-saver O-ring screws. Also turn the motor to make sure it is not rubbing the inside of the cowl. Using the measurement taken in the previous step, hold the co wl in position and drill a hole through the top of the cowl into the cowl block.
7. Measure and note the distance from the front edge of
the cabanes to the center of the cowl mounting block. (It
should be approximately 7/8" [22mm].)
8. Make sure you ha ve a small drill bit from .040" to .052"
(#60 to #55) [1.0mm to 1.3mm] for drilling the cowl mounting
screw holes. Don’t be tempted to use a 1/16" [1.6mm] drill
found in common drill assortments because it is too large.
10. Secure the top of the cowl to the fuselage block with
a 1.6mm x 4mm Phillips wood screw.
11. Turn the fuselage over. Holding the cowl in position,
drill another hole through the bottom corner into the center of the plywood laminations that comprise the front former and the landing gear mount.
9
12. Secure the cowl with another 1.6mm x 4mm Phillips
wood screw. Drill the third and fi nal hole opposite the one
drilled in the previous step and insert another screw.
13. While you’re adding fi nishing touches, glue in one or
both pilots.
Optional: Add the Flying Wires
The fl ying wires are not required, but they add that one fi nal
piece of scale detail for even more realism. If you do install
the fl ying wires, they should be tight enough to remain taut,
but not so tight as to introduce any twist into the wings. To
make the fl ying wires you’ll need some black hea vy/medium
thread and a toothpick.
of the wing and pull the string through until it stops. Add a few drops of foam-safe CA to the string and toothpick to permanently glue it in.
4. Loop one end of the string around one of the holes in
the top of the outer strut. Lightly pull the line to apply some tension. Then, add a drop of thin CA where it loops around the strut and allow to harden. Tie off the other end of the fl ying wire to the other hole in the top of the strut the same way. Cut off excess thread.
1. Use a pin to puncture the molded-in dimples in the
bottom wing up through the top skin.
2. Cut an approximately 30" [760mm] length of black
thread. Insert both ends of the thread down through the hole you punctured in one of the wings.
3. Cut two 1/4" [6mm] pieces from a toothpick. Loop the
string around one of the toothpick pieces on the bottom
5. Add the bottom fl ying wires to the other side of the
bottom wing the same way—be certain not to pull the strings too tight or you may introduce twist into the wings.
6. Add the top fl ying wires that go from the top of the
cabanes down to the bottom of the struts—the easiest way is to fi rst tie one end of the thread around one of the holes in the bottom of the outer strut, loop it through the hole in the top of the cabane, then tie the other end down to the other hole in the bottom of the outer strut. Note that the front wire that runs from the bottom of the struts up to the cabane runs between the other wires coming from the bottom of the wing next to the fuselage.

GET THE MODEL READY TO FLY
Check the Control Throws
If the pushrods were connected to the servo arms using the measurements provided in this manual, then the control throws should already be correct, or very nearly correct. However, it’s still a good idea to check the throws since they have such a great effect on how the model fl ies.
1. Prop up the rear of the fuselage on a box or
something similar so the horizontal stabilizer will be level
or very nearly level. Turn on your transmitter and connect
a battery to the ESC.
4. Make sure the up elevator throw you measured is
the same as the throw specifi ed below. Measure the down elevator throw and the right and left rudder throw the same way. If necessary, use the ATVs in your transmitter to adjust the throws. If your radio does not have ATVs and if your throws are not close to the specifi cations provided, you can change the throws by relocating the pushrods on the servo arms. Moving the pushrods inward will provide less throw and moving the pushrods out will increase the throw.
These are the recommended control surface throws:

3. Use the transmitter to move the elevator to full “up”
and note how far the elevator moved. This is the “up”
elevator throw.
Take a few minutes to balance your propeller and a spare
propeller before you fl y. A balanced propeller will help the motor run smoothly and effi ciently.
If the propeller is unbalanced, use a single-edge razor blade or a hobby knife to scrape material off the heavy blade until you can get the propeller to balance.
11
Balance the Model (C.G.)
More than any other factor, the C.G. (center of gravity/ balance point) can have the greatest effect on how a model fl ies. If you value your model and wish to enjoy it for many fl ights, DO NOT OVERLOOK THIS IMPOR TANT PROCEDURE. A model that is not properly balanced may be unstable and possibly unfl yable.
2. Optional: Fit the servo cover over the servo
compartment. If necessary, use a couple of small strips of tape to hold the cover in place.
3. If you haven’t done so already , attach a strip of the softer,
“loop” side of the included Velcro hook-and-loop material to
the motor battery. Install the motor battery in the fuselage to the other Velcro strip you attached earlier.
1. Mount the propeller (not included) to the propeller
adapter with the prop-saver O-ring that came with the RimFire
motor. A Great Planes 8 x 6 ElectriFly PowerFlow™ Slow­Flyer propeller (GPMQ6610) is recommended. The easiest way to mount the prop is fi rst to hook the O-ring around one
of the screws, fi t the propeller, and then use a small (#00) Phillips screwdriver to loop the O-ring around the propeller
hub and the other screw . Suggestion: Purchase spare Prop Saver O-Rings (GPMG1405).
At this stage the model should be in ready-to-fl y condition
with all of the systems in place including the motor, complete radio system, ESC, propeller and battery.
4. Place the model upside-down. Use two pencils or
ballpoint pens to lift the model at the middle dimples you marked earlier with the template, noting the recommended balance point.
12
This is where your Tiger Moth should balance for the fi rst fl ights. Later, y ou may experiment b y shifting the C.G. 3/16" [4.8mm] forward or 3/16" [4.8mm] back to change the fl ying characteristics. Moving the C .G. forw ard will improv e the smoothness and stability and allow your Tiger Moth to perform tighter turns, but the model will fl y slightly faster. Moving the C.G. aft allows the model to fl y more slowly, but will require slightly more pilot control in tightly-banked turns. In any case, start at the recommended balance point and do not at any time balance the model outside the specifi ed range.
one of the fuselage sides under the horizontal stab. A good place to attach nose weight is to the top of the “motor box” right behind the fi rewall. Do not attach nose weight to the cowl because it will cause stress around the mounting screw holes.
6. Once you know how much weight is required, attach it
in the fuselage. Then, recheck the balance.
If the model is balanced properly it should rest level when viewed from the side. If the tail is down the model is “tail-
heavy” and nose weight will be required. If the nose drops
the model is “nose-heavy” and tail weight will be required. If you are using the components recommended in this manual
it is likely that the model will balance at the recommended C.G. location, or possibly require 1/4 to 3/8 oz. [7g to 11g] of
nose weight.
Charge the Batteries
Follow the battery charging instructions that came with your radio control system to charge the transmitter batteries. You should always charge your transmitter the night before fl ying, and at other times as recommended by the radio manufacturer.
CAUTION: Unless the instructions that came with your radio system state differently, the initial charge on new transmitter and receiver batteries should be done for 15 hours using the slow-charger that came with the radio system. This will “condition” the batteries so that the next charge may be done using the fast-charger of y our choice . If the initial charge is done with a fast-charger the batteries may not reach their full capacity and you ma y be fl ying with batteries that are only partially charged.
MOTOR SAFETY PRECAUTIONS
5. If any weight is required to get the model to balance,
fi rst determine how much by placing segments of Great Planes “stick-on” lead (GPMQ4485) over the location on the
fuselage where it will be attached inside and rechecking the
balance. A good place to attach tail weight is to the inside of
Failure to follow these safety precautions may result in severe injury to yourself and others.
Use safety glasses when starting or running motors.
Do not run the motor in an area of loose gravel or
sand; 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 motor.
Keep loose clothing, shirt sleeves, ties, scarfs, long
hair or loose objects such as pencils or screwdrivers that may fall out of shirt or jacket pockets away from the prop.
13
FLYING
Ground Check & Range Check
When you get to your fl ying site follow the manufacturer’s
instructions that came with your radio to ground check the
operational range of your radio . This should be done both with
the motor off and with the motor running at various speeds. If the motor or control surfaces do not respond correctly or
move erratically without command, do not fl y! Find and
correct the problem fi rst. Look for loose servo connections or
broken or loose motor or battery wires.
Execute turns to see how the Tiger Moth reacts. The Tiger Moth should be able to execute tightly-banked turns with a diameter of approximately 15’–20’ [4.5m – 6m] (although this is not so important if you are fl ying in a large arena or outdoors). If, during the tightest turns the Tiger Moth noses up and seems to get “stuck” in the turn, nose weight may be required. If you don’t feel the Tiger Moth fl ies slowly enough or if it doesn’t react quickly enough to your control inputs, tail weight (or removing a portion of any nose weight) may help.
While the Tiger Moth is still high in the air and you have plenty of battery power, another good exercise is to cut the throttle and observe how the Tiger Moth glides . This will giv e you an indication of what it will do when it’s time to land.
Flight
Taking off from the ground is desirable if you are fl ying
indoors or outdoors where there is a smooth runway surface .
However, if no smooth surface is available the Tiger Moth
may easily be hand-launched.
No matter where you fl y, the fi rst thing you should do is
check the controls after turning on the transmitter and
connecting the battery. Make sure the controls respond and
in the correct direction.
T o tak e off from the ground, simply set the model down f acing
into any prevailing breeze. Smoothly advance the throttle all
the way. Initially, the rudder will have little effect, but after a
second or two when there is suffi cient airfl ow the rudder will
become effective. Use the rudder to steer the model. When the Tiger Moth has gained suffi cient fl ying speed apply
“up” elevator, establishing a gentle (20 – 30-degree) climb.
If hand-launching your Tiger Moth, double-check to make
sure that the controls are working correctly. Then, apply full
throttle. Facing into any pre v ailing wind, gently toss the Tiger
Moth into the air. Apply “up” elevator to establish a climb. Once well clear of the ground make the fi rst turn away from
yourself. Use the trims to get the model to fl y straight-and-
level at your preferred fl ying speed—in smaller arenas/
gymnasiums you will probably be most comfortable fl ying your Tiger Moth at about 1/4 – 1/3 throttle. In larger arenas
or outdoors you will probably fl y your Tiger Moth at 1/2 or
higher throttle settings.
When ready to land, simply cut motor power and make the fi nal turn to your landing area. Allow the Tiger Moth to establish a slightly nose-down attitude to maintain airspeed. If necessary, modulate the throttle and elevator to control the glide path. As you get closer to the ground continue to apply “up” elevator, causing the Tiger Moth to fl y slower and slower until it fi nally touches down the precise moment it can no longer fl y.
One fi nal note about fl ying your model. Have a goal or fl ight plan in mind for every fl ight. This can be learning a new maneuver(s), improving a maneuver(s) you already know, or learning how the model behaves in certain conditions (such as on high or low rates). This is not necessarily to improve your skills (though it is never a bad idea!), but more importantly so you do not surprise yourself by impulsively attempting a maneuver and suddenly fi nding that you’ve run out of time, altitude or airspeed. Every maneuver should be deliberate, not impulsive. F or example , if you’re going to do a loop, check y our altitude, mind the wind direction (anticipating rudder corrections that will be required to maintain heading), remember to throttle back at the top, and make certain you are on the desired rates (high/low rates). A fl ight plan greatly reduces the chances of crashing your model just because of poor planning and impulsive moves. Remember to think.
Have a ball! But always stay in control
and fl y in a safe manner.
GOOD LUCK AND GREAT FLYING!
