Hi guys ! First post here
So today I went for a maiden flight of the new version of my octocopter, loaded with AC 3.1 and all set to test the autotune on chanel7. But arriving at the field, I realize it was way too windy to test the autotune. So I started flying it in Stab mode with Simple mode activated. But since I was really curious to test the autotune, I fired it a couple of times : went to Alt Hold and fired the Chanel 7 trigger . The copter reacted as per the manual. Back to Stabilize and then I test Loiter. Worked great a few times until it completly go crazy, heading at full speed in one direction, so back to stabilize and I manage not to crash it. Then I take it for a flight to the other side of the field, and then it goes crazy again, just as if the simple mode was off. I managed to find the nose of the octocopter and bring it back close to me until it crashed becaue it was out of control.
Here is my setup :
Octocopter 1000mm
Arducopter APM 2.5.2
GPS U-blox NEO + external Mag (RCtimer)
8 x 380kv Rctimer 4108 motors
8 x 40A SimonK OPTO ESC
8 x 14x4.5 Gemfan Propeller
2 x 5800 mAh 6s Lipo
Retractable Landing Gear
Logs attached.
Any ideas of what could happen ?
