"Hi all,

Thank you very much for your comments!

I mounted the miniAPM as usual with gel pads as I do always and did not care about vibrations (it had always worked so far, and the vibe…"

Hey guys,I' ve just build a RoboCat270 for some FPV speed fun. As I am a great fan of my APMs in my other quads I thought I should build it with a miniAPM. I added m8n GPS, OSD and telemetry link, as I really enjoy these things.The quad is powered…

I apologize, I should have clarified. I am running arducopter 3.2.1 on a Pixhawk with a F450 frame. I have EKF turned off and yet seeing an EKF failsafe error."

"Hi Steve,
thanks for your reply.
At least I did not see any power lines or transformers nearby. I was sort of in the middle of nowhere. I also do not understand why I need these features, but since I turned them both off, I have no problems at all."

"I simply dont understand it. When I fly behind my house, the copter has no problems at all. When I fly at my favorite flying site, I get several incidents of EKF_CHECK-2 with the corresponding failsafe. Today I was suffering 5 or 6 of these till my…"

"I had the same thing on friday.
Was very suprised that without any obvious problem suddenly my quad went down from loitering in 3 m hight into a muddy meadow. Nothing I could do against it in that short of a time.
The gimbal and camera was deep in a…"

after reading post upon post about Y6es I did the same as you did. Bigger props on the lower motors. Then I made some measurements on the amp draw of the motors. Guess what, the lower motors where working much harder then the upper ones. I am…"
