A 2-point calibration is sufficient for TAIL ROTOR. Take care that the servo is
not stalled (mechanically obstructed) at its end-points (P1, P5)!
All settings for throttle and collective pitch must be completed before the TAIL
ROTOR mixer is configured. Subsequent changes usually require a correction.
The TAIL ROTOR mixer is only activated in the Damping mode of the gyro. In
Heading mode, it is switched off (see section 5.4.5 "Gyro" on page 122). If you do
not use Damping mode, you can replace the mixer with the RUDDER control function
(Servo > Assign main menu, see section 5.6.2 "Assignment" on page 142).
Coll.+ / Coll.-
Separate configuration of the collective pitch mixers for the tail rotor when
climbing and descending:
o Coll.+: correction for climbing
o Coll.-: correction for descending
The exact values can only be established through a programme of flight
testing, and vary according to many parameters.
Rudd.Diff.
Reduce tail rotor travel in one direction.
Offset
Pitch angle (offset) for the tail rotor to compensate for the torque at 0º
collective pitch (main rotor).
Zero point
The origin for the static tail rotor compensation mixer.
Starting from this collective pitch setting angle in the direction of "climbing",
the "Collective -> Tail rotor" mixer is added using the value set for Coll.+.
The value set for Coll.- is applied in the other direction (descending).
