4) Servo direction, "tail rotor"
(If external gyro is used, skip this step.) The LED must flash four times (press
SET button briefly if necessary). Select correct direction of tail rotor servo by
moving the aileron stick to either side: with tail rotor stick to the right, the nose
should move to the right, the tail rotor must "blow" to the right. You can now
adjust the tail rotor neutral point, since heading hold is disabled in Step 4.
Check the setting, and store it with a long press on the SET button until LED
flashes again.
5a) Installed position (sensor direction)
The LED must flash five times (press SET button briefly if necessary). The
HeliCommand now needs to know its installed orientation, i.e. whether the
round side of its housing is facing right, left, forward or back. Program this
by moving the aileron or elevator stick towards the appropriate side of the
swashplate.
5b) Direction of main rotor rotation
In step 5 move tail rotor stick in same direction as the direction of rotation of
the main rotor (viewed from above), and store it with a long press on the SET
button until LED flashes again.
Concluding the setup
Switch on again (keep unit still during power up) and check the controls. Set
any travel reductions at the transmitter to prevent mechanical fouling, and set
the correct collective pitch range (because travels may now be different to
those set when you were using the transmitter's mixer). Any major travel red-
uctions should be set in the HeliCommand using the PC adaptor. The swash-
plate should now be exactly horizontal; if not, adjust it at this stage.Coarse
adjustment: there should be a point in the middle of the collective pitch range
where all the servo output arms are at neutral simultaneously. If not, unscrew
the output arms and replace them in the correct position. For fine-tuning: adjust
the pushrods and / or use the transmitter trims and then use the SET button so
that the HeliCommand "learns" them again.
For transmitters featuring multiple flight modes (phases): It is important to have
identical trim values for all flight modes while the HeliCommand is activated !
