108 Tail gyro
Gyro gain and operation mode
The tail gyro system of MICROBEAST PLUS helps to keep the helicopter's tail in position
while flying around. It makes the rudder only react to stick inputs but not to external
effects. Before the first flight, you have to set the correct amount of gyro gain in order to
adapt the reaction of the gyro system to your specific helicopter model. Additionaly, you
have to choose between two different operation modes:
• Normal-Rate mode - here the tail gyro of MICROBEAST PLUS only acts as damp-
ening that decelerates sudden rotations caused by external influences. Slow, constant
rotational movements will not be compensated. Thus the tail does not drift in hover due
to the main rotor torque, a perfect mechanical adjustment of the tail rotor is essential
(see the section to Setup menu point E & F
1
). But even with perfect mechanical
adjustment you will always encounter some drift on the rudder axis due to crosswinds
and the pilot has to constantly perform corrections when doing hovering flight. In
high-speed flight on the other hand the tail will be aligned in flight direction by the
wind, so curves can be flown very dynamically and the pilot doesn‘t have to constantly
concentrate on controlling the rudder.
• HeadingLock mode - in this mode the tail is actively controlled by the gyro system.
You will barely feel any external influences. By giving rudder stick input, the pilot only
commands the gyro how fast it has to turn the tail. When the stick is in center position
the tail gyro will ensure that the tail keeps locked into position by any means. This
simplifies the control significantly. In hovering flight the beginner can fully concentrate
on the control of cyclic and collective pitch and the advanced pilot can perform 3D
- flight maneuvers such as backwards flying quite easily. The only disadvantage of
HeadingLock-Mode is that the rudder must be steered by the pilot when flying curves.
Otherwise the gyro will try to keep the tail aligned with the initial direction.
