34 SPEKTRUM DX7 • TRANSMITTER INSTRUCTION MANUAL
EN
Back Mixing applies a mix to all related servos in a wing or tail
type. For example, if you select 2 AIL, 2 FLAP in the Aircraft Type
screen, a mix to one aileron channel affects both aileron servos.
The mix response, however, depends on the aileron channel
included in the mix.
A Back Mix also enables you to use fewer mixes to achieve the
desired response, for example adding roll to a split elevator.
The Range Test function reduces the power output. This allows for
a range test to confi rm the RF link is operating correctly. Perform
a range check at the beginning of each fl ying session to confi rm
system operation.
