Different from collective, cyclic pitch dictates the rate of cyclic throw controlling cyclic response. Different helicopter design gives different setting in this pitch, in Trex 450, it is recommended to keep it at 8°. To adjust cyclic pitch, follow the steps below:
a) set zero degree pitch (make sure the rotor would not spin by use of throttle hold switch or unplug the motor)
b) line up the blades with the tail boom
c) give the cyclic a pure full aileron input
f) measure the blade pitch and this is the aileron cyclic pitch, adjust swash mixing to achieve desirable cyclic pitch
g) line up the flybar with the tail boom ( blades perpendicular to the tail boom if flybarless)
h) give the cyclic a pure full elevator input and this is the elevator cyclic pitch
i) adjust the elevator rate in swash mixing to achieve the desirable cyclic pitch
j) adjust cyclic travel end point to make the opposite direction pitch even
At last, rotate the rotor head slowly to check for servo binding, lower the rate if this happens
