The Jackal 50 ARF is a Mike McConville design capable of reaching speeds in excess of 100 mph when using an engine in the .50-.60 cu. in. range on a stock muffler. We highly recommend the use of the Evolution® 60NX engine and performance muffler (EVOM1) combination, as this really allows the Jackal to perform to its fullest potential and reach speeds in excess of 120 mph.. The removable top hatch allows access to the radio equipment while the 2-piece wing allows for easy transport. The optional Pneumatic Robart Retracts (HAN502) provide additional performance and jetlike good looks.

 2. Separate the elevator and stabilizer. Set the three

hinges aside at this time. Prepare the left and right stabilizer and elevator at this time.

 3. Insert the elevator torque rod into the elevator. The rod

will fit tightly in the slot as shown. Note that the threaded section of the torque rod faces to the top of the elevator.

 4. Insert the torque rod in the remaining elevator. With

both elevators flat on your work surface, check to make sure the threaded sections of the rods are parallel. If not, slightly bend one of the torque rods until they are parallel. Not checking the torque rods will result in uneven throw and undesirable flight characteristics.

 5. Once the torque rods are aligned, remove them from

the elevators. Use medium grit sandpaper to scuff the wire where it contacts the elevator.

 6. Use 30-minute epoxy to glue the torque rod to the

elevator. Use a toothpick to force the epoxy into the hole in the leading edge of the elevator. Use low-tack tape to hold the torque rod in position until the epoxy fully cures. Glue the torque rods in both elevator halves at this time.

Note: Keep the nylon bushing slid away from the elevator to avoid getting epoxy in the bushing.

 7. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill

a hole in the center of each hinge slot. This creates a tunnel for the CA to wick into, creating a better bond between the hinge and surrounding wood. Prepare both elevators and stabilizers at this time.

7Hangar 9 Jackal 50 ARF

Page 8

 8. Apply a small amount of petroleum jelly to either side

of the bushing. Work the lubricant into the bushing to help prevent epoxy from entering it when gluing the bushing to the stabilizer.

Important: Hinge only one elevator to the stabilizer at this time. The remaining stabilizer/elevator must be left unhinged.

 10. Check the fit of the elevator to the stabilizer. The

elevator should fit tightly against the stabilizer.

Important: Make sure the bushing does not extend over the root edge of the stabilizer. If so, the stabilizer will not fit correctly when installed.

 9. Place a T-pin in the center of three hinges. Insert the

hinges into the elevator as shown.

 11. Separate the elevator from the stabilizer. Attach

the elevator to the stabilizer by mixing a small amount of 30-minute epoxy and applying it to the nylon bushing to secure the bushing to the stabilizer. Make sure to slide the nylon torque rod bushing as close to the elevator as possible.

 12. Remove the T-pins from the hinges. Position the

elevator so there is a 1/16-inch (1mm) gap between the tip of the elevator and stabilizer. Saturate each of the hinges on both the top and bottom of the hinge. Set the assembly aside to cure.

8 Hangar 9 Jackal 50 ARF

Page 9

Important: Allow the CA to cure WITHOUT using CA accelerator. This is necessary to allow the CA to soak into the hinge, creating the best bond between the hinge and surrounding wood.

 13. Once the CA and epoxy has cured, check that all the

hinges are secure by gently trying to separate the elevator from the stabilizer. If any hinges are loose, re-apply CA to the loose hinges.

 14. Break in the hinges by working the elevator up and

down a number of times.

 15. Position the stabilizer in the stabilizer hatch cover.

Insert the torque rod through the slot, then rotate the stabilizer and fit it into position.

 16. Lightly sand the stabilizer tubes using medium grit

sandpaper. Use rubbing alcohol and a paper towel to remove any oil or debris from the stabilizer tubes. Slide the tubes through the stabilizer hatch. The shorter tube is near the leading edge.

9Hangar 9 Jackal 50 ARF

Page 10

 17. Now that the fit has been established, use 30-minute

epoxy to glue the stabilizer to the hatch, and the tubes in the stabilizer. Disassemble the stabilizer, then apply epoxy in the stabilizer sockets and the exposed wood. Apply a small amount of epoxy in the tubes in the stabilizer hatch at this time as well. Repeat Steps 15 and 16 to reassemble the one stabilizer to the stabilizer hatch.

 18. Slide the remaining stabilizer partially on the

stabilizer tubes.

 19. Place a T-pin in the center of the three remaining

hinges and place them in the slots in the elevator. Insert the torque rod into the stabilizer hatch.

 20. You will need to position the stabilizer so the bushing

from the torque rod can be placed and the hinges installed. Remember the torque rod bushing must be positioned as close to the end of the elevator as possible or the stabilizer won’t fit correctly.

 21. Slide the stabilizer into position. It may be necessary

to use a hobby knife to lift the balsa on the bottom of the stabilizer hatch to allow the stabilizer to fit into position.

Important: Check to make sure there is no epoxy on the exposed tubes or base for the remaining stabilizer. If there is, use rubbing alcohol and a paper towel to remove it before it cures.

Note: Read through the next steps as the installation of the remaining elevator and stabilizer does take some finesse.

10 Hangar 9 Jackal 50 ARF

 22. Now that the stabilizer has been fit, we can step

back and use epoxy to secure it into position. Remove the stabilizer and apply epoxy to the stabilizer tubes and to the exposed wood on the stabilizer root rib. When installing the torque rod bushing, make sure to use epoxy on the bushing and in the slot as well. Slide everything together and remove the T-pins from the hinges. Check the gap between the stabilizer and tip of the elevator so there is a 1/16-inch (1mm) gap between the two.

Page 11

 23. Use thin CA to glue the hinges. Make sure to check

and break them once the CA has fully cured.

 24. At this time we recommend that you seal the hinge

gap between the elevator and stabilizer. Use either clear covering or tape to seal the gap to prevent flutter of the control surfaces during high-speed flight.

 25. Thread the nylon torque rod horns on the threaded

ends of the torque rods. They will be flush with the top of the threads as shown.

 26. Place 2–3 drops of thin CA in each of the four holes

that will be used to mount the elevator servo. This will harden the wood, making the screws more secure.

 27. Remove the horn from the elevator servo. Install the

servo in the stabilizer hatch with the output facing away from the elevators. Use the screws included with the servo to secure it in the hatch. Make sure to install the grommets and brass eyelets before securing the servo. Use a #1 Phillips screwdriver to tighten the screws.

Note: Although there are two elevator servo positions, we DO NOT recommend using two servos. This will add too much weight to the rear of the fuselage, making it difficult to balance your model.

 28. Use a pin vise and 5/64-inch (2mm) drill bit to

enlarge the hole in the servo horn. Use side cutters to remove any unused arms so they don’t interfere with the operation of the servo.

 29. Slide a silicone clevis keeper on a clevis. Thread the

clevis on the split pushrod wire. Prepare the pushrod wire with two clevises as shown. Attach the bend in the pushrod wire to a hole in the servo horn that is 1/2-inch (13mm) from the center of the horn.

11Hangar 9 Jackal 50 ARF

Page 12

 30. Center the elevator servo using the radio system.

Attach the servo horn to the elevator servo using the screw provided with the servo. Connect the clevises to the nylon torque rod horns. It will be necessary to adjust the clevis to center both elevator halves. Once centered, slide the silicone clevis keepers over the clevises to keep them from opening accidentally.

 4. Secure the 9-inch (228mm) servo extension to the battery

pack lead using string or a commercially available connector.

 6. Connect the lead from the switch to the receiver. The

receiver is secured in the fuselage using a hook and loop strap. Make sure to use a piece of 1/4-inch (6mm) foam between the plywood and receiver to prevent vibrations from the airframe from entering the receiver.

 8. Apply 2–3 drops of thin CA in the holes for the rudder

servo mounting screws.

 5. Use a hook and loop strap to secure the receiver

battery in the rear of the fuselage.

 7. Use hook and loop tape (not included) to mount the

remote receiver in the wheel well of the fuselage.

Note: We used short pieces of fuel tubing over the antenna of the main and remote receivers to keep them straight.

 9. Remove the horn from the rudder servo. Use a #1

Phillips screwdriver and the screws provided with the servo to mount the rudder servo in the fuselage. Note that the output for the servo faces to the front of the fuselage.

Note: If you are installing fixed flaps, please skip this section and continue to “Flap Stay Installation,” the next section of this manual.

Important: The flap servos cannot be operated using a standard Y-harness. They will move in opposite directions. The options for connecting the flaps to the receiver are as follows:

Option 1: Use a computer radio to mix the flap channel to an auxiliary channel. This will allow the greatest versatility for the actuation of the flaps, allowing the throws and endpoint to be set in the radio programming.

Option 2: Use a JR MatchBox to operate the flap servos. You will be able to set the direction of the servos as well as the throws and endpoints, matching the right and left flaps together.

Option 3: Use a reversing Y-harness. This will operate the flaps, but they will not be able to be adjusted individually. There may be a slight variation between the endpoints and throws between the two servos, but they will operate in unison as flaps.

Note: The installation of the flap servos follows the same procedure as the aileron servos. The reference lines should be drawn on the servo covers at this time.

 4. Use a drill and 3/32-inch (2.5mm) drill bit to drill the

four holes for the landing gear base mounting screws.

 5. Place 2–3 drops of thin CA in each hole to harden the

surrounding wood. This will help prevent the screws from pulling loose on hard landings.

 6. Slide the nose gear strut into the landing gear block.

Place a 4mm wheel collar at the top of the block. Position the collar so the distance between the top edge of the

block and centerline of the axle is 61/8-inch (156mm). Tighten the collar so it leaves a mark on the wire. Use a felt-tipped pen to mark the wire under the block for the steering arm location.

 8. Slide the steering arm on the nose gear strut, then the

landing gear base. The wheel collar can now be placed and the setscrew tightened using a 1.5mm hex wrench. Check the distance between the top edge of the base and axle as shown in Step 6 and adjust as necessary. Slide the steering arm against the base and use a #1 Phillips screwdriver to tighten the screw. Make sure to use threadlock on both screws to prevent them from vibrating loose.

 7. Use a flat file to make two flat areas for the wheel

collar and steering arm setscrews. Make sure the flat areas are parallel to the axle. Make each flat 1/4-inch (6mm) wide.

 9. Pass the cable into a copper crimp. The wire then

goes through the center hole on the steering arm, then back through the crimp. Use a crimping tool or pliers to secure the wire.

Hint: If it is difficult to fit the wire through the crimp, use pliers to slightly flatten the crimp to make it an oval shape when viewed from the end.

24 Hangar 9 Jackal 50 ARF

Page 25

 10. Secure the loose end of the cable to the steering arm

as described in Step 9. Use side cutters to cut the cable so equal portions of the wire extend from the steering arm.

 13. Use 2–3 drops of thin CA in each of the holes for the

screws to harden the surrounding wood. Use six 1.5mm x 6mm sheet metal screws to attach the fixed gear fuselage plate to the fuselage. Use a #1 Phillips screwdriver to tighten the screws.

 15. Secure the wheel on the axle using two 4mm wheel

collars. Remember to place a drop of oil on the axle before installing the wheel and to use threadlock on the setscrews.

 11. Mount the nose gear assembly in the fuselage using

four #6 x 1-inch sheet metal screws. Tighten the screws using a #2 Phillips screwdriver. Insert the steering cables into their respective tubes in the fuselage.

 12. Use 2–3 drops of thin CA in each of the holes for the

screws to harden the surrounding wood.

 14. Use a flat file to make two 1/4-inch (6mm) wide flat

areas on the axle. The first is at the end of the axle, and the second centered 3/4-inch (18mm) from the end of the axle.

 16. Prepare the cables to connect to the rudder servo

by sliding a copper crimp on the wire, then a pull-pull fitting. The cable then goes back through the copper crimp. DO NOT crimp the cable, as it must be adjusted before securing the crimps.

25Hangar 9 Jackal 50 ARF

 17. Insert the pull-pull fittings in the brass pushrod

connectors. With the end of the pull-pull fitting extending 1/4-inch (6mm) through the connector, use a #1 Phillips screwdriver to lightly tighten the screw in the connector to hold the fitting in place.

 18. Adjust the cables so there is light and equal tension

on both cables. Check to make sure that when the rudder servo is centered, the nose wheel is parallel to the fuselage center line.

Hint: Use needle nose pliers or hemostats to tension the cables.

 19. Slide the crimp as close to the pull-pull fitting as

possible. This will keep the setting on the cables. Carefully remove the fittings from the pushrod connector and use crimping pliers to secure the position of the crimps. Trim any excess cable using side cutters. Place the fittings back in the connector and tighten the screw in the connector to secure the fittings. Use threadlock on the screw to prevent it from vibrating loose.

Important: It may be necessary to check the tension of the cables periodically as they can stretch over time. Also use the connectors and fittings to adjust the steering if you find your model does not taxi straight down the runway.

 28. Install the servo arms on the retract servos as shown.

The nose gear is shown in the down position. Make sure the switch on the radio is also in the position you will want as the down setting.

 30. Slide the pushrod tube in the fuselage with the end

that was not sanded toward the nose gear. Center the tube and use medium CA to glue the tube to the center former and the former near the servo compartment. Do not glue the tube near the nose gear as it must be able to move to operate properly.

 32. Insert the pushrod wire into the pushrod tube. Once

the threads are exposed near the nose gear, thread a 2-56 nut on the threads as shown. The pushrod can then be threaded into the actuator for the nose gear.

Hint: It is easier to thread the pushrod wire into the actuator when the nose gear is in the up position.

 33. It’s now time to set the length of the retract linkage.

With the nose gear in the down and locked position, use the radio to move the servo to the down position. Adjust the length of the linkage so the ball end fits on the ball without any binding. Use the radio to move the retract servo to the up position. Check that the retract is in up and locked. You may need to fine-tune the length of the linkage to allow it to move from up to down, locking the retract in both positions.

31Hangar 9 Jackal 50 ARF

Page 32

 34. Use the radio to cycle the gear a number of times,

checking that the length of the linkage is correct. Although it is important the gear locks in both the up and down positions, it is most critical it is fully locked when down or it may collapse on the runway during takeoff or landing. Also make sure the servo is not binding at either position, as this will quickly drain the receiver battery. Take your time to set the linkage perfectly. Once complete, tighten the 2-56 nut against the retract actuator to prevent it from changing position.

 3. Use a rotary tool and cutoff wheel to cut the length of

the nose gear strut to 51/2-inch (140mm) as shown in the photo below. Measure from the bottom edge of the mounting flange of the retract housing.

 4. Use a drill and 3/16-inch (5mm) drill bit to enlarge the

hole in the wheel.

 5. Slide the axle through the hole in the wheel. Slide a

nylon spacer on the axle from the opposite side.

 7. Use a rotary tool and cutoff wheel to trim the length of

the axle. Use a flat file to make a 1/4-inch (6mm) wide flat where the setscrew from the adapter will rest.

Note: We recommend the use of a drill press to enlarge the hole in the wheel so it is straight.

 6. Slide the adapter on the axle. Use a felt-tipped pen

to mark the location for the setscrew and the outside edge where the axle will need trimmed.

 8. Place a drop of light machine oil on the axle before

sliding it into the wheel so it rolls smoothly during takeoff and landing.

 9. Assemble the nose wheel assembly as shown. Use

threadlock on the setscrew before tightening it on the flat area made in the previous step.

 11. Position the retract mechanism on the rails. Center

the mechanism on the rails, and align the rear edge of the mechanism with end of the hardwood blocks. Use a pencil to transfer the location of the mounting screws on the rails.

 13. Place 2–3 drops of thin CA in each hole to harden the

surrounding wood. This will help prevent the screws from pulling loose on hard landings.

 10. Before attaching the nose wheel assembly to the

nose gear wire, use a flat file to make flats for the setscrews on the nose gear wire for the adapter. Use the setscrews included with your retracts and threadlock to secure the adapter to the nose gear wire. Make sure the nose wheel is aligned with the retract air cylinder when the steering arm is perpendicular to the actuator.

 12. Use a drill and 3/32-inch (2.5mm) drill bit to drill the

four holes for the landing gear base mounting screws.

 14. Pass the cable into a copper crimp. The wire then

goes through the hole in the steering arm, then back through the crimp. Use a crimping tool to secure the wire. Secure each end to the steering arm at this time.

Hint: If it is difficult to fit the wire through the crimp, use pliers to slightly flatten the crimp to make it an oval shape when viewed from the end.

34 Hangar 9 Jackal 50 ARF

Page 35

 15. Secure the loose end of the cable to the steering arm

as described in Step 13. Use side cutters to cut the cable so equal portions of the wire extend from the steering arm.

 16. Mount the nose gear assembly in the fuselage using

four #6 x 1-inch sheet metal screws. Tighten the screws using a #2 Phillips screwdriver. Insert the steering cables into their respective tubes in the fuselage.

 17. Use 2–3 drops of thin CA in each of the holes for the

screws to harden the surrounding wood. Use six 1.5mm x 6mm sheet metal screws to attach the retract gear fuselage plate to the fuselage. Use a #1 Phillips screwdriver to tighten the screws.

 18. Prepare the cables to connect to the rudder servo by

sliding a copper crimp on the wire, then a pull-pull fitting. The cable then goes back through the copper crimp. DO NOT crimp the cable, as it must be adjusted before securing the crimps.

 19. Insert the pull-pull fittings in the brass pushrod

 20. Adjust the cables so there is light and equal tension

on both cables. Check to make sure that when the rudder servo is centered, the nose wheel is parallel to the fuselage center line.

Hint: Use needle nose pliers or hemostats to tension the cables.

the drill so it is 1-inch (25mm) from the chuck to prevent accidentally drilling through the top of the wing.

 6. Slide the main gear into the landing gear base. The

top of the gear will be flush with the top of the base.

 8. Use a #2 Phillips screwdriver to tighten the screw

in the base on the wire. This will leave a mark on the wire where you will need to file a flat area for the screw. This will prevent the gear from rotating during takeoff and landing. Use a flat file to make the flat on the wire.

 4. Drill the four mounting holes for the landing gear

base using the drill and drill bit prepared in the previous step.

 5. Place 2–3 drops of thin CA in each hole to harden

the surrounding wood. This makes it difficult for the screw to pull loose on hard landings.

 7. Place the gear and base on a flat surface. The wheel

axle will rest flat on the surface when the base is resting flat. This will position the wheel straight forward when installed.

 9. Once the flat is on the main gear wire, insert it back

into the base and tighten the screw. Check the alignment to make sure the flat is in the correct location. Once complete, use threadlock on the screw and tighten it to secure the landing gear wire.

 10. Place the block in the wing. Check that the spring

faces the rear and the wire for the wheel faces the wing root. If not, you will need to prepare the opposite landing gear wire for this particular wing panel. Use four #6 x 1-inch sheet metal screws and a #2 Phillips screwdriver to secure the landing gear block in the wing.

will also need the fuselage assembly, which includes the fuel tank.

Don’t forget the pushrod linkage and other items to connect the throttle servo to the carburetor.

 2. Inspect the fuel tank to determine the correct

orientation before installing it into the fuselage.

 3. Place the fuel tank in the fuselage, securing it with the

hook and loop straps.

Note: You will be required to drill the engine mount for the engine. If you will NOT be using a drill press, make sure to use threadlock on the screws that attach the engine mount rails to the firewall in the following step.

 4. Attach the engine mount rails to the firewall using four

8-32 x 3/4-inch socket head machine screws and four #8 washers. Use a 1/8-inch hex wrench or ball driver to tighten the screws. Make sure to use threadlock on the screws so they don’t vibrate loose in flight.

 5. Position the engine on the rails. Measure the

distance from the firewall to the front face of the drive washer. Adjust the engine so this measurement is 47/16-

inch (113mm). Mark the engine mount rails for the engine mounting screws using a pencil.

 6. Use a drill and 9/64-inch (3.5mm) drill bit to drill the

four holes in the engine mount rails for mounting the engine.

Hint: It is recommended to use a drill press for drilling the holes in the engine mount rails. This will make them nice and straight in the rails. Make sure to use threadlock on the screws that attach the rails to the firewall when installing the rails back on the firewall.

 7. Use four 6-32 x 1-inch socket head machine screws,

four #6 washers and four 6-32 locknuts to attach the engine to the mounting rails. Use a 5/16-inch nut driver and 7/64inch hex wrench or ball driver to tighten the hardware.

 8. Trim the clear cowling to fit the engine. We placed the

spinner backplate on the engine crankshaft to help locate the clear cowling while trimming. Use low-tack tape to hold the cowling in position on the fuselage. Use a felt-tipped pen to mark the locations for the cowl mounting screws on the clear template. This will help when aligning the clear template to the painted cowl.

 9. Slide a silicone clevis retainer over the small nylon

clevis. Thread the clevis on the throttle pushrod and slide the pushrod into the tube in the firewall. Connect the clevis to the outer hole of the carburetor arm and slide the clevis retainer over the forks of the clevis to prevent it from opening accidentally. Bend the pushrod slightly so it does not bind when the carburetor is opened or closed.

48 Hangar 9 Jackal 50 ARF

Page 49

 10. Slide the clear cowling over the painted cowling.

Align the marks made on the clear cowl in Step 8 for the cowl mounting screws to align the clear cowl and painted cowl. Use a felt-tipped pen to transfer the opening from the clear cowling to the painted cowling. Make the marks on the painted cowling roughly 1/8-inch (3mm) inside the opening in the clear cowling to allow some material to remove when making the final fit of the painted cowling.

 11. Use hobby scissors to rough the opening for the

engine. Cut the cowling along the paint line behind the engine so it can be installed and removed easily.

 12. Use a rotary tool and sanding drum to fit the cowl

to the engine. Work slowly removing small amounts of material. Use the spinner backplate and cowl mounting holes to help in aligning the cowling while trimming. The cowl only needs to fit over the engine at this time. Final adjustments can be made once the cowl is secured to the fuselage.

 13. Check that there is a gap of 1/16-inch (1.5mm)

between the spinner backplate and cowling. If not, slightly oval the mounting holes in the cowl so there is a small gap to prevent the backplate from rubbing on the cowl.

 14. Attach the cowling to the fuselage using four 4-40 x

3/8-inch button head screws. Use a 5/64-inch hex wrench or ball driver to tighten the screws. Trim and connect the fuel line connected to the fuel tank clunk line to the carburetor fuel inlet nipple.

 15. Attach the propeller and spinner backplate to the

crankshaft using the washer included with the engine and the adapter included with the model. Use a 12mm open end or box wrench to tighten the nut. Do not use pliers as this will not tighten the nut and will round the corners so a box or open end wrench won’t fit.

49Hangar 9 Jackal 50 ARF

Page 50

 16. Place the spinner cone on the backplate so the

openings for the propeller in the cone are not touching the propeller. Use a 4mm hex wrench or ball driver to install the spinner mounting screw.

 17. Attach the muffler to the engine using the hardware

included with the muffler. Connect the line from the fuel tank vent to the muffler. Trim the line so it won’t interfere with the operation of the engine. Use a small amount of threadlock on the screws to prevent them from vibrating loose.

Hint: The installation of the optional EVOM1 muffler will increase the speed of the engine over 1500 rpm on an APC 10 x 7 propeller.

 18. Place 2–3 drops of thin CA in the holes for the

throttle servo mounting screws. Remove the horn from the throttle servo and use the hardware included with the servo and a #1 Phillips screwdriver to mount the throttle servo in the fuselage. Route the lead from the servo under the tray and plug it into the throttle port of the receiver.

 19. Prepare the servo horn for the throttle by enlarging

a hole that is 1/2-inch (13mm) from the center of the horn using a pin vise and 5/64-inch (2mm) drill bit. Insert the brass pushrod connector in the hole of the servo horn that is 1/2-inch (13mm) from the center of the horn. Use the connector backplate to secure the connector to the horn. Use side cutters to remove any arm on the horn that will interfere with the operation of the radio system.

 20. Center the throttle servo using the radio system.

Slide the pushrod wire through the hole in the brass pushrod connector and attach the servo horn to the throttle servo so it is perpendicular to the servo center line. This provides equal throw to both low and high throttle. Secure the horn using the screw removed from the servo and a #1 Phillips screwdriver.

 21. Move the throttle servo to the low-throttle position

using the radio system. Use the linkage to close the carburetor then use the 3mm x 4mm machine screw to secure the pushrod to the brass pushrod connector. Use threadlock on all metal-to-metal fasteners to prevent them from vibrating loose.

50 Hangar 9 Jackal 50 ARF

front and rear of the canopy floor. The front of the floor is wider than the rear as shown in the photo.

 4. Use a pin vise and a 1/16-inch (1.5mm) drill bit to

drill a hole through the canopy floor and into the base of the pilot. Use a #2 x 1/2-inch sheet metal screw to secure the pilot to the canopy floor.

Note: This section covers the installation of two pilot figures (optional) in the canopy. If you choose not to install the pilots now, they can be added later. You will need to install the canopy floor as described in Step 6 and 7.

 1. Locate the items necessary to attach the canopy floor

to the canopy. If you are installing pilots, you will also need the items listed under the optional required items.

 3. Use medium CA to glue the forward pilot figure to the

canopy floor. Position the pilot about half-way between the front and center mounting holes. Make sure the shoulders of the pilot hang over the edge of the canopy floor equally.

 5. Use medium CA to glue the shoulders of the rear

pilot to the canopy frame. Allow the CA to fully cure before proceeding.

Note: Do not use CA accelerator as it may damage the canopy material.

56 Hangar 9 Jackal 50 ARF

Page 57

 6. Position the canopy floor in the opening in the canopy

hatch. If you installed a pilot, you will need to rotate the hatch to fit the shoulders of the front pilot.

 7. Use six 1.5mm x 6mm sheet metal screws to secure

the canopy floor. Use a #1 Phillips screwdriver to tighten the screws.

 8. Use a pin vise and a 1/16-inch (1.5mm) drill bit to drill

a hole through the canopy floor and into the base of the rear pilot. Use a #2 x 1/2-inch sheet metal screw to secure the pilot to the canopy floor.

 9. Attach the canopy to the fuselage to complete the build

of your model.

Center of Gravity

An important part of preparing the aircraft for flight is properly balancing the model.

Caution: Do not inadvertently skip this step!

The recommended Center of Gravity (CG) location for your model is 63/8-inch to 65/8-inch (162mm–168mm) back from

the leading edge of the wing as shown with the battery pack installed. Mark the location of the CG on the top of the wing with a felt-tipped pen.

When balancing your model, support the plane inverted at the marks made on the wing with your fingers or a commercially available balancing stand. This is the correct balance point for your model. Make sure your model is assembled and ready for flight before balancing.

Adjust the motor battery as necessary so the model is level or slightly nose down. This is the correct balance point for your model. You should find the CG to be very close with the battery installed as shown in this manual. Mark the location of the battery on the battery tray using a felt-tipped pen so it can be returned to this position if it is removed from your model.

After the first flights, the CG position can be adjusted for your personal preference.

Control Throws

Rudder:

Preight

 1. Turn on the transmitter and receiver of your model.

Check the movement of the rudder using the transmitter. When the stick is moved right, the rudder should also move right. Reverse the direction of the servo at the transmitter if necessary.

 2. Check the movement of the elevator with the radio

system. Moving the elevator stick toward the bottom of the transmitter will make the airplane elevator move up.

 3. Check the movement of the ailerons with the radio

system. Moving the aileron stick right will make the right aileron move up and the left aileron move down.

 4. Use a ruler to adjust the throw of the elevator, ailerons

and rudder.

Aileron:

High Rate:

Up: 1/2-inches 13mm 18 degrees Down: 1/2-inches 13mm 18 degrees

These are general guidelines measured from our own flight tests. You can experiment with higher rates to match your preferred style of flying.

Note: Travel Adjust, Sub-Trim and Dual Rates are not listed and should be adjusted according to each individual model and preference.

Check Your Radio

Before going to the field, be sure your batteries are fully charged per your radio’s instructions. Charge the transmitter and motor battery for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases, the radio should be charged the night before going out flying.

Before each flying session, be sure to range check your radio. See your radio manual for the recommended range and instructions for your radio system. Each radio manufacturer specifies different procedures for their radio systems. Next, run the motor. With the model securely anchored, check the range again. The range test should not be significantly affected. If it is, don’t attempt to fly! Have your radio equipment checked out by the manufacturer.

Double-check that all controls (aileron, elevator, rudder and throttle) move in the correct direction.

Check the radio installation and make sure all the control surfaces are moving correctly (i.e., the correct direction and with the recommended throws).

Check all the control horns, servo horns, and clevises to make sure they are secure and in good condition.

Range Test Your Radio

Before each flying session, and especially with a new model, it is important to perform a range check. It is helpful to have another person available to assist during the range check. If you are using a Spektrum transmitter, please refer to your transmitter’s manual for detailed instructions on the range check process.
