Recommended Radio Equipment You will need a minimum 6-channel transmitter, receiver and four servos. You can choose to purchase a complete radio system. If you are using an existing transmitter, just purchase the other required equipment separately. We recommend the crystalfree, interference-free Spektrum™ DX6i 2.4GHz DSM® 6-channel system. If using your own transmitter, we recommend the JR SPORT™ MN48 Mini servos. If you own a Spektrum radio, just add a DSM2™ receiver and four JR SPORT MN48 mini servos.
Aileron Installation Required Parts Wing panel with aileron (right and left) CA hinge (10 total) 3. Use a pin vise and 1/16-inch (1.5mm) drill bit to drill a hole in the center of each of the hinge slots in the wing. Note that there are five (5) slots, even though only three (3) hinges were removed in the previous step. 5. Insert the hinges in the slots of the aileron. The T-pins will keep the hinges centered so they are positioned equally in the aileron and wing when installed.
7. Check the alignment of the aileron. Use a ruler to make sure the end of the aileron is aligned evenly with the wing tip. 11. Flex the aileron through its range of motion a few times to break in the aileron hinges. When hinging the aileron, do not use CA accelerator. The CA must be allowed to penetrate the hinge or the bond between the hinge and wood could fail. 9. Flex the aileron slightly so the hinges can be seen. Make sure not to change the hinge gap in the process.
Aileron Servo Installation Required Parts Nylon clevis (2) Clevis retainer (2) Assembled wing panel (right and left) Control horn screw with hardware (2) Servo extension, 6-inch (152mm) (2) Aileron linkage wire, 21/2-inch (64mm) (2) Radio system Servo with accessories (2) Heavy-duty servo horn (2) Nylon control horn (2) Always use threadlock on metal-to-metal fasteners to prevent them from vibrating loose. 4.
5. Secure a 6-inch (152mm) servo extension to the aileron servo lead using string or a commercially available connector. This will keep the servo and lead from disconnecting inside the wing. 7. Position the servo in the servo opening. Make sure it is centered and not touching the sides of the opening. Use a pencil to mark the locations for the servo mounting screws. 6. Insert the extension into the opening for the aileron servo.
13. Insert the Z-bend of the 21/2-inch (64mm) linkage wire into the hole in the servo horn as shown. When installing the servo horn on the aileron servo it must be positioned parallel to the aileron hinge line. 15. Thread the clevis on the aileron linkage wire. With the radio system on, adjust the clevis so the aileron is aligned when the clevis is attached to the control horn. Slide the clevis retainer over the forks of the clevis to prevent it from opening in flight. 11.
