Note
: If you have installed fixed gear, skip
to the next section “Wing Installation.”
1. Locate the hardware to install the retracts. The wing
assembly is also required for this section of the manual.
2. Use the radio system to extend the retracts to the
open position. Use a rotary tool and cutoff wheel to trim
the retract strut length to 4

inches (105mm) from the top
of the wheel collar. Use a flat file to remove any burrs after
trimming the strut length.
3. With the retract in the up position, place the retract
in the wing. Carefully trim the wing sheeting to allow the
strut to fit inside the wing. The slot must be wide enough to
allow the retract to operate without it hitting the sheeting.
4. With the retract centered in the mount, use a pencil
to mark the front of the retract opening for the notch needed
to allow the rotational pin to clear.
