GET THE MODEL READY TO FLY
Check the Control Directions
o 1. Turn on the transmitter and receiver and center the
servos. Make certain all the servo arm screws are in place.
o 2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If necessary,
adjust the pushrod lengths to center the control surfaces.

o 3. Make certain that the control surfaces and the electric
motor respond in the correct direction as shown in the
diagram. If any of the controls respond in the wrong direction,
use the servo reversing in the transmitter to reverse the
servos connected to those controls. Be certain the control
surfaces have remained centered. Adjust if necessary.
Set the Control Throws
Use a ruler to accurately measure and set the control throw
of each control surface as indicated in the chart that follows.
If your radio does not have dual rates, we recommend setting
the throws at the
low rate setting.
NOTE: The throws are measured at the widest part of the
elevators, rudder and ailerons.
These are the recommended control surface throws:

Note: It is highly recommended that a computer radio with
exponential be used, if this airplane is to be flown using the
3D control surface throws. Use the exponential function to
lessen the control movement around center without changing
the control surface endpoints. -50% is a good exponential
starting value to use for these 3D rates. Feel free to adjust
the 3D throw exponential value to suit your flying style.
