ROTOR
If you experiment with the ultra-fast pirouette rate,
make sure that your flight battery and fuel tank
are secure. Also be certain that your model’s tail
rotor drive train is up to the task.
The Tail Rotor AFR or D/R function within the
transmitter is used to adjust the pirouette rate of
the helicopter. For example at 100% D/R, with the
gyro set to F3C mode, the helicopter will achieve
a 450 deg/sec pirouette rate. If you would like the
model to pirouette faster, then increase the AFR
or D/R. If you would like the model to pirouette
slower, then decrease the AFR or D/R.
The gain should be raised until the tail begins to
oscillate quickly (also called Tail Wag). Once this
point has been achieved, reduce the gain by a cou-
ple of percent and test fly the model again. Check
and set the gain for each flight mode. Typically
the gain will be lower for the Idle up 1 and Idle up
2 flight modes due to the higher head speed being
used. The gain for the Hold condition can also
be much higher than other flight modes since the
head speed is lower and the engine vibration is
minimized.
