Start with the ailerons. Place the servo and
servo cover in position without the mounting
screws. Use a ruler to measure the length of the
control rod.

}}}}
Bend a V into the control rod halfway between
the two attachment points. Make a Z-bend at
the opposite end of the control rod ensuring the
length matches the measured distance. The V
will allow for minor adjustments of the control
rod length.
}}}}
Tip: for greater ease of adjustability a control
rod adjustment mechanism such as threaded
clevises or linkage stoppers can be used.

Remove the aileron servo cover, thread the
control rod through the control horn and the
servo arm and re-mount the flap servo cover
with all four screws. Feed the servo wire
through the channel provided in the wing.

Connect the flap servos to your radio and set
them to the fully retracted position (regular
flight mode). Place the flaps in the fully
retracted position (0° of flaps).

Create the flap control rods in the same manner
the aileron control rods were created. Insert the
flap control rods and mount the flap servos
using all four servo cover screws.
