Step 8
Plug a 24" servo extension onto the
outboard servo. Either tie the servo
leads together, using a commercially
available connector, or use unwaxed
dental floss to secure the extensions
to prevent them from coming
loose during flight.
Step 9
To run the servo extensions, use a
long rod and make a little hook at
one end of it. Pass it through the
wing panel and connect your servo
lead to the hook with masking tape
and pull it through.

Step10
Use 3" extension for inboard servo
and install the servo.
Step 11
Use 1.5" aluminum servo arms.
Step 12
Measuring from hinge line vertically
to pivot point on the Dubro Control
Horn connector should be at 1.7"
inches for the proper amount of
aileron throw. Hook the servo arm to
the control horn using the provided
4/40 titanium rods.
Use provided ball links to complete
the installation.
Note that you don't need more throw
than 45 degrees for Ailerons. Don't
alter the set up to get more than 45
degree deflection.
