Hi guys!
I have a issue with my Trex 700E DFC (3GX v5). When hovering it starts to drift backwards. I can really see the whole hell starting tilting back and it drifts backwards...
I have checked the swash with a swashlevel tool, the servos are at 90 degres (as good as I could see) and I have made the entire 3GX setup. I have checked the servos for binding and there are non.
This only happens when the hell is up in the air, I have spooled it up on the ground at almost mid stick, just before it lifts and looked at the swash to see if there are any vibration issues or anything that would suggest why the swash tilts back but the swash is completely level on the ground (checked this for 1 minute, no movements on the swash), this happens only in the air...
I have also checked CG with canopy and battery on and it looks good, no tilting forward or backward.
Some forums say play with the trims but I'm almost 100% sure that this is not a good option with 3GX, others say that I should extend the elevator link a little bit to compensate for this but that also sounds like a bad suggestion, no?
Any thoughts or ideas?
