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 swiveling to the side continuously due to air drafts or air turbulences.
• The adjustment controller for the contact sensitivity of
the gyroscope (1) is located on the right side of the
receiver/controller module (2).
• 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.
