helicommand-m-series-label

  • Dual independent instrument systems and sophisticated software for excellent reliability.
  • New type of sensing process provides stable positional monitoring, completely independently of the visible horizon.
  • Electronic triple-axis gyro with accurate attitude control and artificial horizon.
  • Instruments can be activated individually; variable stabilisation level.

Integral functions:

 

Tail rotor gyro

The HeliCommand unit includes an integral fully-featured heading hold gyro as standard. Of course, a separate gyro can be used as an alternative if required.
Auto-Trim
The system also features automatic trim. Pressing a button at the transmitter automatically neutralises the three control axes elevator (pitch-axis), aileron (roll-axis) and tail rotor. The auto-pilot trim is only required during the first flight (after initial installation). However, the trim can also be used during manual control. The automatic trim system only requires a period of reasonably smooth flight lasting at least seven seconds in order to define correct trim values. The values are stored, but can also be amended at any time.
Swashplate mixer
The system also includes an integral fully-featured swashplate mixer (H1, H3 90°/120°/140°, H4 90°/90+45°), which makes it possible to control any current type of helicopter using a simple radio control system (without swashplate mixers). In this case the USB-PC-adaptor and PC-software are required to set up the syste (included in all HeliCommands from July 2010!).
The mixers are set up using a new, straightforward procedure, avoiding the need for the user to study menu systems etc.

 

PILOT-channel

The effect of the stabilisation / positional mode is infinitely variable via a separate radio control channel; it can also be switched off for 3D flying.
Three levels of regulation can be selected in flight:
- Stage 0 = Off (conventional)
- Stage 1 = Attitude regulation (stabilisation)
- Stage 2 = Positional and “ground-speed” regulation

 

Fail-safe

A superior fail-safe function for use with FM receivers. If the radio link fails, fail-safe responds very quickly and virtually continuously: the aileron and elevator functions are returned to neutral, while the collective pitch function retains the last valid value.
