RE: Official T-rex 450 XL SE Thread
I have the DX6, GY401, S9650. Here is what I've got for settings (maybe this will help)
GY401 switch is set to reverse (I have it hanging upside down on a gyro mount in the rear)
DX6 Elevator D/R Switch is my HH/Rate Mode selector
DX6 Flight Mode Switch is my Normal/Idle Up Mode selector
RVO is set to 0%
RUD is set to Norm
GER is set to Norm
RUD Trav Adjust is set to 100%
GER Trav Adjust is set to 58%
This setup works perfect for me. Hope that helps!
