Section 9: Final Assembly

Required Parts

• Side force generator (2)

• Fuselage

• Hatch

• Canopy

• 4-40 x 1/2" screw (8)

• #4 washer (8)

• Decals

• Pilot

• #2 x 1/2” sheet metal screw (2)

Required Tools and Adhesives

• Plywood

• Medium CA

• Hobby knife

• Receiver

• Radio switch harness

• Receiver battery

• Shoo Goo

• Masking tape

• Hex wrench: 3/32"

• Drill

• Drill bit: 3/32" (2.5mm)

• Canopy glue



Step 1

Wrap the receiver and receiver battery in protective foam

to prevent damage that may be caused by engine vibration.

Attach the battery and receiver to the plywood tray.



Step 2

Secure the radio tray into the fuselage using two

#2 x 1/2" sheet metal screws. It may be necessary to

shift the battery forward or aft to balance the model as

described in the section “Center of Gravity.” Plug in

any servo leads or extensions at this time and connect

any extensions necessary for the aileron servos.
