I am setting up a new trex 450 pro w/ the 3GX system and have run into a strange problem with regards to the elevator gyro. Instead of the swash plate tilting back and forward, all three cyclic servos move the entire swash up and down. I have set up many 3G systems, this is my first 3GX set up. Any info regarding this would be greatly appreciated. Thanks

Something was not right during DIR setup. Does collective and cyclic work right during setup? Is collective at zero during setup?

I'm not sure about the 3g system but with the 3 g x you must set it up mechanically as if it had a fly bar. By that I mean 120 ccpm in the radio first. then you setup 3 g x in dir mode

3G and 3GX are identical. You need to be working properly in first step of DIR mode before going through steps 2-5 that teach the 3GX the geometry

I did go thru set up in dir mode, and everything works as should when the gyros are bypassed. Set up was done at half stick w/ 0* of pitch, and am using the 120ccpm mix. I am starting to think its the gyro and not me, though I have a hard time believing Align sent out a bad gyro system.
