Temperature Adjustment; Supplementary Notes - ROBBE 3D GYRO Notice De Montage Et D'utilisation

5. General information
5.1 Model requirements
The high sensitivity of the gyro, the powerful response of the tail rotor and the high speed
with which the tail rotor reacts combine to place much higher loads than usual on the tail of
the model helicopter. This in turn requires a torsionally rigid tail rotor drive system and a
strong tail rotor gearbox. We recommend rigid drive systems, as they are better able to
absorb the forces exerted by the rapid changes in load. The mechanical linkage to the tail
rotor must also be as free-moving and direct (minimum slop) as possible.

5.2 Temperature adjustment

Although the gyro system is temperature-compensated as far as possible using the cur-
rently available solutions, it is still necessary for the gyro to be allowed to adjust itself to the
ambient temperature. For best results we recommend that you leave the gyro switched on
for about 5 minutes at the start of a flying session so that it can adjust to the surrounding
temperature. After this period switch the system off and then on again.

5.3 Supplementary notes

· If you are using an RC system with flight mode dependent ATV, e.g. an FC 28, you can
set tail rotor servo travel (ATV) and gyro gain separately for each flight mode, and these
settings can then be called up automatically when you operate the flight mode switches
„Idle-Up 1" and „Idle-Up 2".
· Depending on the combination of main and tail rotor you are using, you may find that
the tail boom oscillates (swings from side to side) slightly in Normal mode. This may be
due to an excessively high gyro gain setting, but it can also be the result of tail rotor bla
des which are too long or too wide. In this case the solution is to shorten the tail rotor
blades by about 3 - 5 mm.
· When the gyro is switched on it detects and stores the configuration of the tail rotor and
Aux channels and the position of the REV switch. If you ever need to connect the „Aux"
and „Rx" plugs to different receiver sockets, or if you use the reverse function, it is then
necessary to switch the gyro off and on again so that it can read in the new configurati
on and store it.
