The Heli-Command stabilizes
the geographical position of the model helicopter it
also stabilizes its flight attitude. The
HeliC-ommand incorporates several control and
measurement systems (triple axis gyros and an
optical CCD sensor) to provide a superb of
stability. It is ideal for the beginner. It adds a
level of control and confidence that prior to this
time has been unavailable to any model helicopter
pilot. The HeliCommand provides a level of safety
and accident reduction that previously has been
unknown in the realm of helicopter modeling. Dual
redundancy (in both the hardware and software
programming) throughout was designed into the Heli-Command.
In addition to all of the above the HeliCommand
incorporates a full Failsafe unit incase of radio
failure.
Integral functions:
- Tail rotor
gyro - The Heli--Command 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 stabilizing / 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 (stabilization)
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
stabilization in inverted flight
- switchable support
for brief 3-D maneuvers.
The HeliCommand
"Rigid-Stabi" is another version of the system:
In addition to all the functions of the Heli-Command
3D, this variant provides stabilization for
helicopters which are not fitted with a mechanical
stabilizer bar (flybar). This applies, for example,
to some scale machines and helicopters with
multi-blade rotor heads. This special
attitude-holding stabilization 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.
