Step 19
Use a 5/64-inch bit in a pin vise to enlarge the outer
hole of the servo arm, then install an EZ link. Use
needle nose pliers to press the keeper into place.
Step 20
Set the servo in place in the nacelle and mark the
mounting hole locations with a pencil.
Step 21
Remove the servo and use a 1/16-inch drill bit in a pin
vise to drill the mounting holes. Apply a drop of thin
CA to each of the holes to strengthen the wood. Allow
the CA to cure without using accelerator.
Step 22
Feed the throttle servo lead through the hole in the
spar and through the wing to the wing root. Position
the servo with the output shaft to the left-hand side.
Use the hardware provided with the servo to install it
with a #1 Phillips screwdriver.
Step 23
Insert an 11 3/4-inch hook and loop strap through the
forward slots in the nacelle tray.
Step 24
Guide the fuel lines through the slot in the firewall and
use the hook and loop strap to secure the fuel tank in
place. Note that the tank stopper and vent tube should
be towards the top.
