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 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.

Flap Throw
The Landing throw on the fl aps can be set up to 80 for landing. This creates a lot of drag, and on windy days, the
model will slow very quickly. Always test the amount of throw at a safe altitude fi rst.

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 30˚, mix in 1/8-inch (3mm) of down elevator
With landing fl ap set at 80˚, mix in 1/4–3/8-inch (7–10mm) of down elevator
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.
