Hey guys, I have a RVJET fitted with a pixhawk.
Pixhawk is mounted ~4 inches to the rear from CG, I did this to accommodate as much battery space as possible.
I did the level/sensor calibration with the bottom surface of the wing perfectly level.
In manual mode, it flew great (little bit of up elevator was required to keep a level flight). However, when I tried FBWA and LOITER, the plane dove into a 30 degree dive, and had to switch back to manual mode to save it.
I tried using AHRS_Y trim to the maximum 17 degrees, and it didn't help much.
Does this mean...
1. I have to level the aircraft with the nose up in 30 degrees?
2. Adjust the physical servo arm, so that it will fly with a little bit of up elevator in level position? since it flies level that way in manual mode?
3. Move the pixhawk to the middle? my thought was if it was a few inches off the center, it would compensate fine.
4. combination of all three?
I already had a pretty bad crash from plane going into failsafe mode from a faulty antenna and it has been a very frustrating endeavor for me. please let me know what I should do.
Here's the log from the last crash I had.
