1. Hold a ruler against the widest part of the control surface
and measure the high rate throw fi rst.

2. Adjust the location of the pushrod on the servo arm or
on the control horn fi rst. Then, use the endpoint adjustment
in your transmitter to fi ne tune the throws.

3. Measure and set the
low rate

set the high and low rate throws for the rest of the control
surfaces the same way.

If your radio does not have the ability to set three throw
rates, we recommend setting the throws at the low and
high rate settings for the fi rst fl ight.

4. Once the throws are set, apply a drop of threadlocker
to the threads and tighten the 4-40 nuts against the clevises.
Slide the silicone retainers over the clevises.
IMPORTANT! IMPORTANT! IMPORTANT!
Now that you have the throws set, be sure to set the failsafe
on the radio.
