3. When balancing your model, make sure it is assembled
and ready for flight. Support the plane inverted at the marks
made on the wing with your fingers, or use a commercially
available balancing stand. This is the correct balance point
for your model.
4. You should find the CG to be very close with the
components installed as shown in this manual. If the nose
of your aircraft hangs low, add weight to the rear of the
aircraft. If the tail hangs low, add weight to the nose of the
aircraft. Self-stick weights (HAN3626) are available at your
local hobby store and work well for this purpose.
After the first flights, the CG position can be adjusted for
your personal preference. Use a balance point between

characteristics.
Moving the CG aft of the rear limit will enhance the
model's snap roll and tumbling characteristics, but low
speed handling will become more difficult, particularly in
the landing phase. Use caution if experimenting with CG
positions rearward of the recommended range.

Control Throws
1. Turn on the transmitter and receiver of your model.
Check the movement of the rudder using the transmitter.
When the stick is moved to the right, the rudder should
also move right. Reverse the direction of the servo at the
transmitter if necessary.
2. Check the movement of the elevator with the radio
system. Moving the elevator stick toward the bottom of the
transmitter will make the airplane elevator move up.
3. Check the movement of the ailerons with the radio
system. Moving the aileron stick to the right will make the
right aileron move up and the left aileron move down.
4. Use a ruler to adjust the throw of the elevator, ailerons
and rudder.

These are general guidelines measured from our own flight
tests. You can experiment with higher rates to match your
preferred style of flying.
Travel Adjust and Sub-Trims are not listed and
should be adjusted according to each individual
model and preference. Always install the control
horns 90 degrees to the servo centerline. Use
sub-trim as a last resort to center the servos.
We highly recommend re-binding the radio
system once all the control throws are set. This will
keep the servos from moving to their endpoints
until the transmitter and receiver connect.
