Center Of Gravity (Cg) Adjustment; Control Direction Test - Horizon Hobby UMX Whipit Instruction Manual

Center of Gravity (CG) Adjustment

The CG location is 36mm back from the leading
edge at the wing root.
This CG location has been determined with the
recommended 1S 150mAh 3.7 Li-Po battery
installed in the battery cavity located on the bottom
of the aircraft.
Balance the model on edge of a metal ruler to
fi nd the Center of Gravity. Place the ruler on the
underside of the airframe at the CG location shown
in the image to the right. Move the battery forward
or aft until the model closely balances at
this location.

You should bind your aircraft and transmitter before doing these tests.
