1. Use a box or something similar to prop up the
bottom of the fuselage so the horizontal stabilizer
and wing will be level. Hold a ruler vertically on your
workbench against the widest part (front to back) of
the trailing edge of the elevator. Note the measurement
on the ruler.
❏
2. Measure the high rate elevator throw fi rst. Move
the elevator up with your transmitter and move the ruler
forward so it will remain contacting the trailing edge.
The distance the elevator moves up from center is the
“up” elevator throw. Measure the down elevator throw
the same way.

3. If necessary, adjust the location of the pushrod
on the servo arm or on the elevator horn, or program
the ATVs in your transmitter to increase or decrease
the throw according to the measurements in the control
throws chart.
❏
4. Measure and set the low rate elevator throws and
the high and low rate throws for the rest of the control
surfaces the same way.
If your radio does not have dual rates, we recommend
setting the throws at the high rate settings.
NOTE: The throws are measured at the widest part of
the elevators, rudder and ailerons.
These are the recommended control surface throws:

BALANCE THE MODEL (C.G.)
More than any other factor, the C.G. (center of gravity/
balance point) can have the greatest effect on how
a model fl ies and could determine whether or not
your fi rst fl ight will be successful. If you value your
model and wish to enjoy it for many fl ights, DO NOT
OVERLOOK THIS IMPORTANT PROCEDURE. A
model that is not properly balanced may be unstable
and possibly unfl yable.
At this stage the model should be in ready-to-fl y
condition with all of the components in place including
the complete radio system, engine, muffl er, propeller,
spinner and pilot. The fuel tank should be empty.
