44 Mechanical setup of the rudder servo
In the following of this setup step you will be asked to connect the rudder servo to
MICROBEAST PLUS. When doing so plug the servo connector into CH4 output at the
device. Watch out for correct polarity, the black or brown minus wire must be the clostest
to the bottom of the device.

Then attach a servo horn to the rudder servo in such a way that the tail linkage rod
forms a 90 degree angle to the servo horn (or as close as possible) and adjust the linkage
rod as described in the manual for your helicopter. For most helicopters the tail pitch
slider should be centred and the tail rotor blades will then have some positive pitch to
compensate for the torque of the main rotor.
