Likewise, when
the model pitches
nose-down, the
elevator should
go up to
compensate. And
when it yaws
nose-right, the
rudder should go
left.
Note that the
control surfaces
will only be
displaced while
the model is being
disturbed; as
soon as angular
motion stops they
will return to
neutral. So look for
quick twitches of the
control surfaces in
the right directions,
not prolonged
control offsets.
THIS IS VITALLY
IMPORTANT:
If stabilization
moves the
surfaces the
wrong way (i.e., to increase the disturbance) your
model may be uncontrollable (until you switch off stabilization)! To correct this,
change the appropriate switch: J1 (aileron), J2 (elevator) or J3 (rudder).
Just as experienced RC pilots check stick directions before the first flight of the day, so a
pilot using a stabilizer should check that the surfaces move correctly in response to a
disturbance. If you are using channel 8 for Master Gain, set it to the middle of its range
9. Set dual rates and expo in the transmitter
You should already have the control surfaces set up to move in the correct directions and
with the full throws recommended for your model. Now you should adjust the response to
transmitter inputs by setting dual rates (D/R) and expo. A good starting point for D/R is to
set High Rate at 100% and Low Rate at 65-75% for each axis.6 Expo of 20-30% softens
response around neutral and can make smooth flying easier. Stabilization settings also
affect the response of the model to the transmitter sticks, typically reducing sensitivity with
an expo-like effect. To achieve your preferred response, you may need to adjust your rates
and expo once you find out how the model reacts. Note that the dual rate and expo settings
