Integral functions:

• Tail rotor gyro - The HeliCommand unit features an integral high-quality heading-hold gyro. Of course, a separate gyro can also be used if you prefer.
• Auto-trim
• Swashplate mixer
  The HeliCommand unit incorporates a comprehensive integral swashplate mixer (H2, HR3, H4). This makes it possible to control all current types of helicopter using simple radio control systems (without swashplate mixers). In this case the display module or the PC adaptor and software is required in order to carry out adjustments. The mixer settings are entered using a new form of procedure which is very simple to operate; this saves the user the task of studying the menu system etc.
• Pilot channel
  The effect of the stabilising / positioning mode can be adjusted proportionally using a spare radio control channel; it can also be switched off completely for 3-D flying.
• The in-flight switchable gain system offers three different positions: Stage 0 = Off (conventional)
  Stage 1 = Attitude regulation (stabilisation)
  Stage 2 = Position-holding and "ground-speed" regulation
• Fail-safe
  High-quality fail-safe function with FM receivers. If the radio link fails, the fail-safe responds extremely quickly and almost continuously, setting the roll-axis and pitch-axis functions to neutral, whilst maintaining the collective pitch function at the last value.
• attitude stabilisation in inverted flight
• switchable support for brief 3-D manoeuvres.

The HeliCommand "Rigid-Stabi" is another version of the system:
In addition to all the functions of the Heli-Command 3D, this variant provides stabilisation for helicopters which are not fitted with a mechanical stabiliser bar (flybar). This applies, for example, to some scale machines and helicopters with multi-blade rotor heads. This special attitude-holding stabilisation reliably prevents the characteristic tendency of "flybar-less" rotor heads to balloon up abruptly.

Model helicopters with a rigid head are more agile, contain fewer parts and consume less motor power. The HeliCommand "Rigid" offers a broad field for experimentation in the future.
