
Step 7
Attach two quick connectors to the servo arm using quick
connector washers and retainers.

Step 8
Connect the retract servo to your radio system and
electronically move the servo to the retracted position.
Slide the 8 7 / " retract control wires through the quick
8
connectors as shown and secure the servo arm to the
retract servo.

Step 9
With the retract servo in the retracted position, push the
retract linkage to manually retract the landing gear. Install
3mm set screws into the quick connectors and tighten
them to secure the retract linkage.

Step 10
Check the actuation of the retracts, making sure they
lock in both the up and down positions. Make any
necessary adjustments to the linkages as necessary for
proper operation of the retracts. Once complete, double-
check all set screws to make sure they are tight. A little
threadlock may also be a good suggestion for these set
screws as well.
Hint: Adjustments and fine tuning can also be
made to the retract linkages from inside the
wheel wells.
Remember: It may take some time to get the
retracts adjusted so the servo does not stall
when the landing gear is up and extended.
 
Step 11
Install the wheel well once the retracts have been
adjusted. Trim the wheel well to allow for clearance of
the retract strut. Roughen the bottom side of the well and
surrounding covering using medium sandpaper. Glue the
wells using 6-minute epoxy.
Hint: Use clear tape and tape the wells
into position when flying from rough surfaces.
This will allow easy access to the linkages in
case they might need future adjustments.
