Section 3
Speed control operation
The ESC is set for optimal performance at the factory and should not be changed. Before connecting the battery, make
sure the throttle is in the lowest (off ) position. If the throttle is not in the lowest, off position, the speed control will not
initialize. If this happens, you will need to disconnect the battery and repeat the initialization sequence.
flying Your Plane
Before taking off , perform a radio range check and make sure all your control surfaces are operating in the proper direc-
tion. Take off into the wind and climb to 50 feet to begin your trim out procedures. Once trimmed out, feel free to test the
performance of the plane by performing a variety of aerobatic maneuvers.
PREPARING FOR FLIGHT
Step 12: balancing Your Model
Check the center of gravity (CG) on your model by
balancing it on your fi ngers. The CG should be about
3 ~ 3.4 inches (76 ~ 86 mm) behind the leading
edge of the model as shown below. You can adjust
the CG by moving the battery forward or backwards.
