horns as a guide, drill the mounting holes
through the aileron halves.
5) Mount the control horns by inserting the
screws through the control horn bases and
aileron halves, then into the mounting back-
plates. Do not overtighten the screws or the
backplates may crush the wood.
6) Thread one nylon adjustable control horn
onto each aileron control rod. Thread the
horns on until they are flush with the ends of
the control rods.
7) With the aileron servo centered and the
aileron even with the trailing edge of the

INSTALLING THE LANDING GEAR.

1) The blind nuts for securing the landing
gear are already mounted inside the fuselage.
2) Using the hardware provided, mount the
main landing gear to the fuselage.
3) Place the fuselage inverted on the work-
bench in a suitable stand. Set the landing
gear in place and use a screwdrive to secure
the landing gear to the fuselage using bolts
M4x20mm and washers. Make sure to use
the threadlock on the bolts so they don't vi-
brate loose.
