Horizontal attitude
Set the unit as close to vertical as possible, i.e. parallel to the main rotor shaft!
The electronic compensation means that an angled installation would only be
noticeable when the pilot gives a tail rotor command.
Miniature helicopters with particularly large blade pitch angles invariably hover
with a more pronounced tilt; this is necessary to counter-act for the greater tail
rotor thrust. You can compensate for this tilt using the PC adaptor, or see the
page 38: „fault-finding".
Notes regarding internal combustion engines
•
The unit must be installed as far from the exhaust as possible.
•
Effective vibration protection is very important, as invisible vibration from the
engine can be a particular problem. If you can feel the HeliCommand unit
vibrating when the engine is running, even though it is installed as directed,
we recommend additional vibration damping measures.
The safest option is a metal plate (3 mm aluminium or 1.5 mm steel) which
is first stuck to the HeliCommand; the foam strips are then applied between
this plate and the mounting surface. Additionally secure the HeliCommand
with thin soft rubber band.
Alternatively you could consider installing the unit in a different location,
where vibration is not so severe.
•
Avoid running the motor unnecessarily rich, to avoid clouds of smoke
confusing the sensor.
•
To prevent soiling we recommend that you install a protective tube, or (better)
a cubic box under the sensor. Its internal dimensions must take the vision
cone into account. Be sure to clean the window regularly right to the edges.
