o 3 . Locate a 2-56 x 36" threaded pushrod, one nylon
clevis, and one silicone retainer . If you are using a two-
stroke engine, position the silicone retainer on the pushrod
and thread the clevis onto the pushrod so that at least 1/16"
[1 .6mm] of thread is visible past the barrel of the clevis . If you
are using a four-stroke engine with the carburetor mounted
near the firewall, you will need to make a Z-bend in the
unthreaded end of the wire . Use a pair of pliers or a set of
Hobbico Z-bend pliers (HCAR2000) to do this . Remove the
engine’s throttle arm and fit it to the pushrod .
o 4 . Apply thread-locking compound to the throttle arm
screw and install the throttle arm . Slide the pushrod into the
pushrod tube and attach the throttle arm to the carburetor .
If your throttle arm included a lock washer, don’t forget to
install it too . Note: You may have to bend the pushrod slightly
to get it to line up with the throttle arm .

o 5 . Fit a short servo arm to your throttle servo . Use
your radio to determine where to position the arm on the
splined output shaft . Pick the arm that will be 90° to the
servo case side when your throttle stick is exactly centered
(half-throttle) . Cut off the remaining arms . Fit a screw-lock
pushrod connector to the arm and use a nylon retainer to
secure it . Partially thread a 4-40 x 1/8" [3 .2mm] SHCS into
the pushrod connector .
