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 for general sport and aerobatic fl ying from our own fl ight tests. You can experiment with
higher or lower rates to match your preferred style of fl ying.
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 center line. Use sub-trim as a last resort to center the servos.
Always re-bind the radio system once all the control throws are set to keep the servos from moving to their endpoints
until the transmitter and receiver connect.

MIXING

Flap to Elevator Compensation
There is no precise number for down trim required when fl aps are applied. This can vary slightly from plane to plane
and certain set ups. Use the measurements provided as a starting point and adjust as necessary.
With takeoff fl ap set at 1
With landing fl ap set at 3
A fl ight mode setting is very useful for this aspect of set up as it allows trim inputs in various fl ap stages while in fl ight.
This allows for in-fl ight adjustments and not having to land to adjust via trial and error. Most modern computer radios
can trim various fl ap settings.
PREFLIGHT CHECKLIST
• Charge the transmitter, receiver and motor batteries. Follow the instructions provided with the charger. Follow all
manufacturer's instructions for your electronic components.
• Check the radio installation and make sure all control surfaces (aileron, elevator, rudder, and fl aps) move correctly
(i.e., the correct direction and with the recommended throws).
• Check all the hardware (control horns, servo horns, and clevises) to make sure they are secure and in good condition.
• Prior to each fl ying session (and especially with a new model), perform a range check of your radio system. See your
radio manual for the recommended range and instructions for your particular radio system.
