Hello,
after migrating from a ladybird frame to a QAV400 frame with N4 and M4 v2 , I just did a quick test on my backyard and I found some issues. I had a lot of troubles controlling the altitude.
I only flew it on manual mode. First of all, the throttle is extremely sensitive, very hard to maintain hover. Besides that, when it takes off, it does at very high speed, it's not an smooth usuall take off, it's like it's holding and suddenly goes like a rocket. The little time I had on the air, I saw small high freq oscillations on roll axis mostly.
After carefully reading some forum posts, I think, I can have a vibration problems or some high PID values. Here are some logs. I'm curious why mot8 output isn't logged.
I can fix the throttle sensitive thing with a proper curve on the tx but I think it can be a sympton of some major problems. My PID values are the default ones on beta A4 firmware and I'm using SimonK flashed ESCs, the quad flies great with CC3D and NAZA, I'm surprised vibrations can affect this much.
Here is the complete log link: https://www.dropbox.com/s/sww27jszbc510 ... L.LOG?dl=0
Any help would be appreciated.
