A servo mounting box is supplied. Glue
it together using thick CA. Mount it in
the front compartment. Space it from
the sidewall to accommodate your en-
gine. This was installed with a 60cc
engine and spaced with 2 pieces of ¼”
X ½” balsa. Make sure the servo arm
clears the tank and any other obstacles
when it moves. The piece of plastic
pushrod just helps absorb a little of the
engine vibration.
If you wish to use a servo to control
your choke, you can cut the mid-plate
appropriately to drop in your servo.
Use 2 pieces of 1/16” ply as doublers
for the screws to have some meat .
The pros is that it give an added
measure of safety (extra kill method)
and is convenient. The cons is that it
adds a little extra weight and may
slightly effect performance. Also a
little more battery drain. A mechani-
cal choke is another option and is pic-
tured.
The bellcrank and hardware for a
mechanical choke hookup is not pro-
vided but can be purchased inexpen-
sively at your local hobby shop.
Position the bell-crank so that the
pushrod exits the fuse about ¾” in
front of the landing gear notch. If you
use a canister muffler, this entire
linkage will have to be repositioned.
