Using the Manual Transmitter Requirements This manual is divided into sections to help make assembly easier to understand, and to provide breaks between each major section. In addition, check boxes have been placed next to each step to keep track of each step completed. Steps with a single box () are performed once, while steps with two boxes () indicate that the step will require repeating, such as for a right or left wing panel, two servos, etc. Remember to take your time and follow the directions.
Hinging the Control Surfaces Required Parts Fuselage Rudder Hinge (3) Wing panel with aileron and flap (right and left) Stabilizer and elevator (right and left) Elevator torque rod (right and left) Tools and Adhesives Hinge glue Sandpaper Low-tack tape Rubbing alcohol Step 2 Step 4 Step 7 Step 9 Separate the elevator and stabilizer. Remove the elevator control horn and three hinges. Set the stabilizer and hinges aside in a safe place.
Step 10 Step 12 Step 13 Step 13 Step 16 Apply hinge glue to the holes in the elevator as shown. Make sure to read the instructions on the glue before beginning the hinging process. Apply hinge glue to the holes in the stabilizer. Slide the hinges into the holes and use a damp paper towel to remove any excess glue. Check that the elevator can move up and down freely. Set the assembly aside to allow the glue to fully cure.
Step 18 Once you have test fit the flap without glue, you can now remove the flap and use hinge glue to secure the flap to the wing panel. Use small pieces of low-tack tape to hold the flap in position until the hinge glue fully cures. Step 19 Repeat Steps 13 through 18 to hinge the remaining flap and aileron of the opposite wing panel.
Step 7 Step 9 Step 11 Mix a small amount of 30-minute epoxy. Apply the epoxy to the end of the blocks that were sanded in the previous step. Position the blocks on the servo cover using the marks made previously. Use small clamps to hold the blocks tightly against the servo cover until the epoxy fully cures. Remove the servo. Use a drill and 1/16-inch (1.5mm) drill bit Use the screws provided with the servo to secure it to the to drill the four holes for the servo mounting screws.
Step 18 Step 20 Apply 2–3 drops of thin CA into each hole to harden the surrounding wood. This provides a harder surface for the screws making them more secure when installed. Use a ruler to measure in 2 /16-inch (75mm) from the inside edge of the aileron. Use a pencil to make a small mark on the aileron. 15 Step 22 Step 23 Step 25 Position the control horn on the aileron so the center of the horn is aligned with the mark made in the previous step.
Step 29 Step 31 With the aileron aligned with the wing tip and aileron servo centered, use a felt-tipped pen to mark the pushrod wire where it crosses the hole in the servo arm that was enlarged back in Step 14. Use side cutters or a rotary tool and cutoff wheel to trim the wire 3/8-inch (10mm) past the bend as shown. Use a flat file to remove any sharp edges after cutting the wire.
Step 5 Step 7 Step 8 Step 10 Step 12 Step 14 Check to make sure you are installing the servo on the correct side of the retract mechanism. The servo will face to the trailing edge when installed. Hold the servo in position against the retract frame. Check the operation of the retract using the radio system. When the retract mechanism is in the “down” position the mounting holes should still be aligned. If not, the linkage may need some more minor adjustments in length.
Step 16 Step 18 Step 20 Step 23 Step 25 Step 27 Remove the wheel cover from one of the main wheels. Use a 1.5mm hex wrench or ball driver to loosen the setscrew that secures the axle to the retract strut. Remove the axle from the strut assembly. Slide the wheel collar on the axle. Secure the collar using a 2mm setscrew. Make sure to use threadlock on the setscrew to prevent it from vibrating loose. Use the radio system to move the gear to the “down” position.
Flap Servo Installation Step 29 Use a drill and 1/8-inch (3mm) drill bit to drill two holes through the gear door as shown. Use care not to tear the covering when drilling through the gear door. Hint: Placing the gear door on a piece of wood while drilling will minimize any possibility of damaging the covering. Step 30 With the gear in the “up” position, attach the gear door to the gear door mount using two 3mm x 8mm machine screws and two 3mm washers.
Step 10 Step 12 Step 14 Use a 5/64-inch (2mm) drill bit and pin drill to enlarge the hole in the flap servo horn. Remove the servo.

Step 15 Step 18 Step 20 Step 23 Step 24 Slide a 2.5mm wheel collar on the tail gear wire. Position the collar 17/8-inch (48mm) from the end of the wire as shown. Use a 3mm setscrew and 1.5mm hex wrench to tighten the setscrew. Use threadlock to prevent the setscrew from vibrating loose. Slide the tail wheel wire into the bracket in the rear of the fuselage. Slide a second 2.5mm wheel collar on the wire from inside the fuselage. Use a 3mm setscrew to keep the collar from falling off the wire.
Step 25 Step 27 Step 28 Step 30 Step 32 Step 34 Use a pin drill and 5/64-inch (2mm) drill bit to drill the three holes through the rudder to mount the control horn. Use care to drill the holes parallel in the rudder so the backplate can be installed on the opposite side of the rudder. Once the CA has cured, you can attach the control horn to the rudder using three 2mm x 32mm machine screws and the control horn backplate. Use a #1 Phillips screwdriver to tighten the screws.
Elevator/Stabilizer Installation Step 36 Step 38 Step 39 Place the access cover back in place on the fuselage. Use a pin drill and 1/16-inch (1.5mm) drill bit to drill four holes through the cover and into the fuselage. Make sure to position the holes so they are roughly 3/32-inch (2mm) from the edges of the cover. Use a 5/64-inch (2mm) drill bit to enlarge the holes in the cover. Apply 2–3 drops of thin CA into each hole to harden the surrounding wood.
Step 6 Step 8 Step 9 Step 10 Step 12 Step 14 Slide the tubes into the fuselage. Use a felt-tipped pen to trace the outline of the stabilizer on the side of the fuselage. Repeat Steps 5 through 7 to prepare the opposite side of the fuselage for the stabilizer. Mix a small amount of 30-minute epoxy. Brush a thin coat of epoxy on the exposed wood of the fuselage as well as to the bare wood of the stabilizer. Slide the stabilizer into position.
Step 16 Step 18 Slide one of the 30 /2-inch (775mm) pushrods, threaded end first, into the elevator pushrod tube closest to the center line of the fuselage inside of the fuselage. 1 Step 20 Use the radio system to center the servo for the elevator.
Step 28 Step 30 Apply 2–3 drops of thin CA into each hole to harden the surrounding wood. This provides a harder surface for the screws making them more secure when installed. Secure the cover to the fuselage using four #2 x 3/8-inch sheet metal screws. Use a #1 Phillips screwdriver to tighten the four screws. The screws only need to be tight enough to secure the cover; don’t tighten them too much and crush the wood of the cover.
Step 8 Step 9 Step 11 Step 13 Step 17 Use medium grit sandpaper to roughen the first 1-inch (25mm) of the tube on each end. Slide the pushrod tube in the hole in the firewall. Use medium CA to glue the tube to the firewall so it is flush with the front of the firewall. Remove the servo and use a drill with a 1/16-inch (1.5mm) drill bit to drill the holes necessary for the servo mounting screws.
Step 19 Step 23 Insert the pushrod into the pushrod tube from the inside of the fuselage. Attach the clevis to the servo arm. Slide the wire into the pushrod tube from the front of the fuselage. Connect the Z-bend to the carburetor arm.
Step 4 Step 6 Use a drill and 1/4-inch (6mm) drill bit to drill four holes in the bottom of the engine mounting box so the ignition module can be secured to the fuselage. Make all the connections between the ignition battery, switch and module according to the instructions provided with the engine. Make sure to secure any loose wires so they do not interfere with the operation of the engine or radio system. Step 5 Place a piece of 1/4-inch (6mm) foam between the ignition module and fuselage.
Step 8 Step 10 Slide the pushrod tube in the hole in the firewall. Position the Remove the servo and use a drill with a 1/16-inch (1.5mm) tube so 25/8-inch (67mm) is exposed forward of the firewall. drill bit to drill the holes necessary for the servo mounting Use medium CA to glue the tube to the firewall. screws. Step 9 Step 11 Position the throttle servo on the same side of the fuselage as the pushrod tube and the output of the servo facing the rear of the fuselage.
Fuel Tank Installation Step 19 Step 20 Step 21 Use the radio system to move the throttle servo to the closed position. Physically close the carburetor on the engine. Make sure the direction of the servo and carburetor arm are working in unison. Use a felt-tipped pen to mark the pushrod where it crosses the outside hole of the servo arm. Use the radio system to move the throttle servo to the full throttle position. Move the carburetor to the full throttle position.
Step 3 Step 5 Step 7 Step 10 Remove the template from the firewall. Use a drill and 5/32inch (4mm) drill bit to enlarge the holes in the firewall. Use a 2.5mm hex wrench or ball driver to attach the X-mount to the motor using the screws provided with the motor. Make sure to use threadlock on these screws as well. Secure the electronic speed control to the bottom of the motor box using two-sided tape and tie wraps. The batteries are mounted in the fuselage from the top side.
Step 2 Step 4 Step 6 Slide the cowling on the front of the fuselage. Use four 3mm x 15mm socket head machine screws to secure the cowl to the front of the fuselage. A 2.5mm hex wrench or ball driver will be required to tighten the screws. Position the spinner backplate on the propeller shaft. The hole may be larger than the adapter shaft, so a spacer has been included to take up any space if the shaft and hole in the backplate are different sizes.
Step 6 Step 8 Slide the propeller on the engine crankshaft. Make sure it is facing the correct direction to operate properly. Use the included spinner screw to secure the spinner cone in position. Use a 5/32-inch hex wrench or ball driver to tighten the bolt to secure the spinner cone.
Step 7 Insert the antenna mast into the mount. The antenna can be easily removed to prevent it from becoming damaged while transporting your aircraft. Cooling Exhaust for Electric Version Note: The following steps are required to install the radiator exhaust for the electric version of your aircraft. This will allow air to pass through the fuselage to provide cooling for the batteries. You can still install the exhaust for a glow-powered aircraft, but it is not necessary to do so.
Step 2 Step 4 Step 7 Step 9 Step 12 Use a ruler and pencil to mark the wing dowel 3/8-inch (10mm) from one end as shown. This is the amount the wing dowel will protrude from the leading edge of the wing. Use a hobby knife with a #11 blade to remove the covering to expose the hole for the wing mounting bolts. Place 2–3 drops of thin CA on each of the bards of the blind nut to keep it from coming loose inside the fuselage.
