I just recently changed my rig a little (dropped the beaver tail/battery location, front mounted gimbal, and added legs, 11" x 4.7 props and 3 axis gimbal). Since changing this, my quad has been very unstable and eradic…
My 3 modes programmed are Alt Hold, Loiter, Waypoint, but I’ve done some data logging and Auto-Trim in Stabilize. Stabilize is fine. When I switch over to Alt-Hold or Loiter, it hovers just fine, but when the wind picks up, it starts to rock and swirl and will drop altitude. If I do nothing, it will come down and smack the ground. Basically, in order to save it, I have no choice but to throttle up.
Props are balanced, again, and again… Rig went from incredibly stable and predictable to really worried about letting this fly.
I also noticed after performing the Auto-Trim, it messed with my Artificial Horizon in MP, but after doing an Accelerometer Calibration, that was fixed. Well then the Accelerometer Calibration ruined my Auto-Trim I just performed. After researching, I guess it’s better to arm a switch as CH. 7/8 and then activate while you’re already in the air? Will be doing that shortly. I’ve also been told to try Auto-Trim… I don’t think this will resolve my issues though.
Has anyone ever experienced this/fixed it? Any input would be appreciated as there are a few of us with Steadidrone’s/APM that have gone this route (legs/gimbal) and are experiencing the same things… The guys Running Steadidrone’s/Naza aren’t having any issues
