are embossed into the wing sheeting, and can be
seen easier if the covering is pressed down
against the sheeting in the area of the wheel well
using your index finger. (Be careful not to
accidentally break the sheeting.)
4. Place a clevis retainer onto a clevis. Thread
the clevis 14 turns onto a 12" [300mm] pushrod.
Attach the clevis to the actuating arm on the retract.
Test fit the retract into the wing. Trim the wing
sheeting as necessary to allow the retract to seat
fully onto the retract rails. Drill 1/16" [1.6mm] pilot
holes into the landing gear rails using the holes in
the retract as a template. Secure the retract into
position using four 3mm x 10mm sheet metal
screws. Repeat the step for the opposite side.
5. Use Quick Connectors on the servo arm to
connect the retract pushrods. Using the radio,
cycle the retracts to make sure they will lock in
both the up and down positions. Adjust the
positions of the quick connectors on the servo arm
if necessary to allow the retracts to lock in both the
up and down positions.
6. Once you have adjusted the linkages, test fit
the retract wheel wells into position. Use medium
CA to glue the wells to the wing.
7. Install the landing gear struts into the retracts.
Using a pen, mark the strut 1/4" [6mm] past the
center of the wheel well when the retracts are
folded into the wing. Cut the landing gear struts off
at the mark and file the edges of the wire to remove
the rough edges.
8. Use an adjustable axle to mount the wheel to
the landing gear strut. Place the axle onto the strut,
and secure its location using the set screw
provided with the axle. Install the main wheels
using eight 4mm wheel collars and eight 3mm x
