Pixhawk / APM 3.1.2 / Quad / Spectrum DX9 w/PPM Encoder
Flew great all morning… Stabilize, Alt-Hold and Loiter.
Then I go to recharge it and afterward it’s acting funny. I have a mini-crash or two. So I keep checking things and all the motors are spinning. Nothing is getting hot either.
I get it up in the air and it starts giving me trouble – almost impossible to control. So I trigger a RTL mode with my switch and it lands me safely (even though that seemed a little “glitchy” (but it could have been a mild breeze too).
Then I go up again – but slowly. I enter loiter mode and it begins behaving just fine (like it did earlier). Then a couple of minutes into the hover, I get a flip of death and it falls to the ground.
- In my log, you can clearly see me enter loiter mode
- Right around the time of the crash, you can see an “RTL” tag – and I’m 100% sure I didn’t trigger an RTL
- Then right after the RTL tag, I see a “Stabilize” tag – and I’m 100% sure I didn’t change to stabilize either
Would someone mind looking at my log and seeing if they recognize the problem? I swear I wonder if the transmitter, receiver or PPM encoder was sending nonsense to the Pixhawk RC inputs. That would be the only explanation, because everything else appears to be mechanically sound.
