11. Fine Tuning of the Model Helicopter
a) Setting the gyrostatic effect
Besides the receiver and both electronic speed controllers for the electric driven motors, there is also a Piezo gyroscope
system integrated in the receiver/regulator module. This gyroscope system helps the tail of the helicopter to remain
stable when hovering and prevents it from swivelling to the side continuously due to air drafts or air turbulences.
In order to adjust the contact sensitivity, you have to
remove the two support screws (1) of the cabin hood
(2) on the left and the right.
Afterwards you can carefully pull off the hood towards
the front.
The adjustment controller for the contact sensitivity of
the gyroscope (3) is located on the right side of the
receiver/controller module. You can make these
adjustments using a small screwdriver. The further you
turn the adjuster to the right, the stronger the corrections
(speed differences of the two rotors). If the adjuster is
turned too far towards the right, the helicopter will tend
to show oscillating movements around the yaw axis
(rotor shaft). In this case, turn the adjuster a little bit
towards the left again.
