#4 Setting up the tail rotor, tail rotor servo and gyro

     

Tail servo setup 

     

Turn the radio on if not already on.

     

Set the Aileron D/R Switch to 0. 

     

The servo should be centered from the previous steps. If it is not you need to go back to the 
centering section and do this servo again. (You need to be in flight mode 1.)

     

With the servo centered, horn on, linkage connected, loosen the servo mount bracket so it can be 
moved on the boom. Position the servo so the tail rotor blade pitch is 0 with the servo arm centered 
as shown (figure M).

     

Also the bracket needs to be rotated until the control arm runs parallel with the boom. (figure N) 

     

Tighten the bracket down once these items are aligned.
