If any of the servo movements are opposite, reverse the
servo direction with the servo reversing switches on
the transmitter.
low rates following the radio system's instructions If
your radio does not have dual rates, set up the plane
using the low rates first and increase the throws as you
get familiar with the plane.
Adjust the throttle
2 For added safety and convenience, the throttle
should be set up so that the engine can be stopped
using the throttle trim To do this, loosen the pushrod
connector screw and move the throttle pushrod so that
the carburetor is completely closed with the throttle
stick and trim lever on the transmitter fully back
(NOTE: If the carburetor does not fully close, adjust the
idle stop screw on the carburetor until it will) Next,
tighten the screw on the pushrod connector Test the
trim lever by advancing it to full This will be a fast idle
position with the carburetor barrel slightly open (about
1/32"). See sketch.

These are the suggested deflections from center.
If you need more control movement, you should move
the clevis to a hole closer to the control surface or you
can install a larger servo wheel and move the rod at the
servo end further out from center If you have too
much movement, move the rod in the opposite
direction See sketches below:
Now move the throttle stick forward to full Make sure
that the carburetor barrel opens all the way See
sketch If it doesn't open far enough or opens too far
(bending the rod) move the pushrod connector in or
out on the servo arm and/or the carburetor arm to gain
or reduce movement Apply a small amount of thin CA
onto the threads of the pushrod connector The throw
will be correct when the carburetor barrel will stop
fully open at the same time the throttle stick reaches
full With the throttle set up properly, you should be
able to run the engine with the trim lever set midway to
the full position (adjusted for a smooth but slow idle)
Then when it is time to stop the engine, simply pull
back the trim to close the carburetor and the engine
will stop running
Adjust the control throws
3 Check the movement of the control surfaces Use a
ruler to match our measurements listed below If your
radio features dual rates, set up both the high and the
Moving the clevis outward on the servo arm
results in more pushrod movement
Moving the clevis inward on the control horn
results in more throw
