Make sure to eliminate all play.
Be sure to install retaining clips as shown.
Rudder servo installed. Keep rods as close to the spindle as possible. Use
retaining clips.
Mount Horizontal Stabilizer
Run servo extensions to the front of the stab saddle
access hole. Connect servos using tape to secure.
Duct tape works well in this application. Make sure all
extensions clear the rudder servo and have adequate
clearance from exhaust pipe area.
Bolt the horizontal stab in place, using 35 mm bolts
and large washers. Use Loctite. Tighten securely, but
do not crush the stabilizer.
Double check to insure the stab sits down flat in its
saddle. You may need to relieve front of saddle
slightly to achieve a perfect fit.
Test elevator and rudder servos through the wiring
harness before proceeding to next step.
Stab bolted in place. Note slight grinding of front stab saddle to allow
stab to sit flat.
Permanently Mount Vertical Stabilizer
Check the hole in horizontal stab at rear to make sure
it is aligned with main spar clamp access hole. En-
large if necessary.
Measure the depth of the front vertical stab spar hole.
Make sure the 12 mm attachment bolt is long enough
to fully capture the threads in the front aluminum spar.
Thread the bolt into the spar, checking for a smooth fit.
(Note: on some early kits, the bolt may be too short.
You can make a trip to the hardware store for a longer
bolt or drill the front spar with a #36 drill and tap for a
