Radio Installation & Setup
Your receiver can be mounted anywhere in the airframe. Adding a small piece of wood across the fuselage behind the wing tube
works pretty well for this airframe.
While the final setup is of personal preference, these are some general guidelines to make your first flight a success.
Control Throws:
Low Rates:
A. Elevator : 10-15 degrees, 15-20% Expo
B. Aileron : 15-20 degrees, 40-45% Expo
C. Rudder : 20 degrees, 45-50% Expo
High Rates:
A. Elevator : 45-50 degrees, 60-65% Expo
B. Aileron : 45+ degrees, 65-75% Expo
C. Rudder : 45+ degrees, 75-85% Expo
Center of Gravity:
The CG is measured from leading edge of wing near the root.
127 mm (5 inch) to 143 mm (5 5/8 inch)
You can adjust your CG depending on your flying style. If you fly aggressive 3D aerobatics, you’ll want to find more of a neutral CG,
meaning that when it’s flown level inverted, it requires little to no do elevator to maintain altitude. If you enjoy sport & precision
aerobatics more, you’ll want a slightly nose heavy CG. To test this, fly left or right at about 3/4 to full throttle and pull to a 45 de-
gree up-line. Roll inverted and let go of the elevator stick. A correct nose heavy CG will slowly arc to the level. A neutral CG should
nearly hold the up-line. A tail-heavy CG will steepen the up-line. Land and adjust your battery back or forward until satisfied. Once
it’s where you like it, mark the battery tray so you can always place your battery in the correct spot. Keep in mind that different
brand batteries and different milliamp packs will differ in weight, and therefore change your CG.
