HeliCommand RIGID
Includes all the features of the HeliCommand 3A and 3D, plus:
RIGID mode for stabilising flybar-less rotor heads (2- or multi-bladed heads),
highly effective in preventing ballooning and tuck-under at high speed and in
gusty conditions.
Optimised pirouette stabilisation. No additional setup necessary.
(Only units from date code 10.08 on the label!)
Suppressed oscillation for elevator. Also useable with standard Hiller flybars.
(Only units from date code 10.08 on the label!)
Eliminates the need for aileron (roll-axis) and elevator (pitch-axis) trim
functions.
Expanded mixer options: Virtual swashplate rotation, and sinus-compensation
(matches unequal pushrod travels caused by the tilting of servo arms).
The pilot channel can be used to select: horizontal mode, position mode,
RIGID mode.
RIGID and horizontal modes even function without visual contact between
the optical sensor and the ground, i.e. no opening is required in the helicopter
fuselage if you do not need to use position mode.
Electronic linearisation to compensate for mechanical irregularities (angular
offset) when using the H4 swashplate linkage.
The PC adaptor (No. 84942000) is required for setting Rigid mode.
Without the PC adaptor the HeliCommand 3D makes use of the parameters
which are pre-set at the factory.
