Contents of Kit

A 7-channel or greater computer radio is highly recommended. This allows the following features:

• Mixing the right aileron to the left aileron (flaperon mix)
• Electronically adjustable aileron differential
• Mixing the right elevator to the left elevator (dual elevator mixing)
• Independent travel and trim adjustments of each elevator half

When you use a 7-channel or greater computer radio, each servo is plugged into its own separate 
channel. Consult your radio manual for specific details on hookup and programming.

Control Throws

Correctly balancing an aerobatic model is critical 
to its performance and flight characteristics. 
Checking the balance on this model is best done 
with two people.

Step 1

Measure back 30%-33% of the whole wing root’s 
length from the leading edge and mark the CG 
range with a felt-tipped pen at the wing tip. This is 
the recommended center of gravity (CG) range.

Recommended Center of 

 

Gravity (CG)

The following is our recommended control throws for your reference.
