HeliCommand 3A No. 8493
• With “auto-pilot” function, stabilises all horizontal control movements:
inclination (tilt), speed, position
• Auxiliary „pilot“ channel for adjusting stabilisation effect and switching
between horizontal mode and position mode
• Integral heading-lock gyro, swashplate mixer and automatic trim
• Second auxiliary channel (“AUX channel”) for gyro gain and mode
(normal/heading lock); optionally for automatic trim.
• Can be confi gured without connection to a PC by simple learning procedure,
for almost all rotor head linkage types with up to 3 servos
• Fail-safe if radio link fails (PPM / FM only): switches to position stabilisation,
collective pitch to ‘hold’.
• Suitable for internal-combustion and electric-powered helicopters
• Can be used indoors and in the open air
• PC adaptor available as accessory for supplementary settings, including:
setup as necessary for HR4-linkage, automatic trim option, freewheel
function for forward fl ight, optimised settings for auto-pilot and tail rotor gyro.
HeliCommand 3D No. 8494
• Includes all the features of the basic “3A” version, plus:
• Horizontal stabilisation for inverted fl ying
• Expanded set-up facilities via PC adaptor (No. 84942000) (additional Expert
settings for optimising 3D mode and control characteristics).
HeliCommand RIGID No. 8495
• Includes all the features of the HeliCommand 3A and 3D, plus:
• RIGID mode for stabilising fl ybar-less rotor heads, highly effective in pre
venting ballooning and tuck-under at high speed and in gusty conditions.
• Eliminates the need for aileron (roll-axis) and elevator (pitch-axis) trim
functions.
• RIGID mode stabilises fl ybar-less helicopters (two or more rotor blades) as
well as conventional fl ybar-equipped helicopters.
• 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.
