6EX-2.4GHZ Setup Help needed

[aahsac]

I'm beginning the CCPM setup on my first heli, a Trex 450S. I am centering the servos and I find that I can not center the "Pitch" servo. This servo is on channel 6 and there doesn't seem to be a trim function for that channel and there is no sub-trim at all.

Thanks,
Stephen

You put the collective/throttle stick on the transmitter in the center of its travel. That will center the pitch servo.
DO NOT HAVE THE POWER LEADS PLUGGED INTO THE MOTOR WHEN DOING THIS.

No need to use subtrim or trim on any of the channels. Just rotate the servo wheel/horn till it lines up correctly.

In thinking through what I did I realized that I lined up the horns on all three swash servos before installing them in the frame. I wasn't paying attention to servo orientation so all three were lined up with the servo horn over the servo. As a result the two front servos that have the arms sticking out off the back of the servo are not mechanically centered.

I am returning my Mensa invitation un-opened.
