Control Direction Test; Control Centering - BNF UMX Radian Instruction Manual

Control Direction Test

Move the controls on the transmitter to make sure the aircraft control surfaces move correctly. Always
keep throttle at the low position during testing.

Control Centering

Before fi rst fl ights, or in the event of a crash,
make sure the control surfaces are centered
when the transmitter controls and trims are
neutral. The transmitter sub-trim must be set
to zero. Adjust the linkages mechanically if the
control surfaces are not centered.
For best performance with AS3X, it is
important that excessive transmitter trim is
not used.
