Hi … I write from Argentina to tell my experience. For several months I have been flying my hexacopter successfully with apm 2.5 board. Very accurate loiter mode, alt hold, and excellent the rtl. The plate is located in a casing of epoxy barometric sensor covered with foam rubber. I’m running version 3.01 of arducopter, and until today, was a happy user of this system. This afternoon, after making two flights in which I was testing my new gimbal brushless, and after eating a rich barbecue with friends flying club, try out again with my hexacopter. The first thing I noticed was that the engines accelerated much more than usual, and when I wanted to raise, the hexa, he lay sideways or forward, so I decided, disconnect the battery and reconnect. The gps status lights and armed, were solid once plucked the hexa, I try again to lift, and this time normally rises, after trying for a few seconds hold alt modes, and then loiter, way back hexa stable, and while I was in hover a few meters out scared me … forward. On this first occasion, nothing broke. Try later, and after reviewing everything ok find, and I get the same thing when I go to take off, start the engine with much more power than usual, and reeling for either side, when I look at the mission planer I see that after the engines were assembled, the artificial horizon, was completely twisted …! Disconnect the lipo, and I reconnect … everything ok, I check again the mission planer … everything ok … and lift the hex … a few seconds and doing a hover … scared out ahead again breakin … this time an arm of hexa (F550 frame). Really I am totally baffled by what happened, and so far, never had any problems. Someone can guide me to find out where you can be my problem …
From already thank you very much …
