BRAKE LINKAGE
Add a #7560 collar onto the second rod and secure it about
3/8" (9.53mm) from the end of the threads. See drawing below.
Bend the brake rod according to the actual size drawing below, including
the angled bend at the short side. Cut the rod to the length shown.
Slide the threaded end of the rod through the disc brake cam. Drop the bent
end of the brake rod through the adapter hole shown. Attach a #7560 collar
with a #6591 set screw to the end of the rod.
Slide on another 7560 collar with #6951 set screw, a #7560
washer, then the #4118 spring, then the #7560 locknut.
Tighten the locknut down until shown in the picture.

Apply full throttle (pull the trigger
of your transmitter all the way
back). Your carb should be fully
open. If it is not, then adjust the
collar nearest to the adapter.
(You may also adjust your
throttle trim according to your
radio's instructions.)
Now apply the brake. Your carb
should be at idle position. The
spring should not be completely
compressed.
ADJUST THE
THROTTLE LINKAGE
Turn on your transmitter
then the kit's electronics
(don't start the engine).
When at idle (trigger of
transmitter not pulled),
adjust the collar near the
adapter so there is up to
1/16" (1.58 mm) of space
between the collar and
pivot.

THROTTLE LINKAGE
Install your stock servo horn to your servo with the stock servo screw. (You
may have to trim away a part of your stock servo horn so the locking collar
for the brake linkage in Step 9 won't hit it.)
Mount the #7557 aluminum throttle pivot to the #7559 adapter with the
#7558 throttle pivot clip, with the clip's inner teeth flaring away from the
adapter.
Screw one #7560 ball cup onto the end of the #7560 throttle rod. Slide on
one #7560 collar about an inch away from the ball cup and tighten it down
with a #6951 set screw.
Slide on the #7560 long throttle spring. Slide the throttle rod through the
throttle pivot, then slide on and fasten the second #7560 collar to the rod so
there is about one inch (xxmm) of space between collars.
Attach the servo horn adapter assembly to your servo horn with the two
#3721 screws provided. See photo for proper orientation of adapter to your
servo.
[photo] Snap the ball cup onto the carb's ball end.
Cut off the remaining part of the throttle rod. Make sure you leave 1/2 inch
(12.7mm) so you can adjust the throttle linkage.
