Hi guys,
I'm new here and new to quads, and have just built my first multi-rotor!
I am using the Hobbyking HKPilot Mega 2.5 with all the accessories you get with it, except for the OSD/FPV stuff as I wanted to get the quad flying properly before adding that, and how right I was to do that!
I have run through the setup procedure in Mission Planner, calibrated the compass/gyro's etc, and had a quick hover last night to make sure everything was working nicely, and it was; great power, nice and quiet, stable etc.
Today, I wanted to check the vibration levels that the APM sees using the Log Bitmask, and whilst hovering, the quad moved away from me so I dialled in some left yaw to turn towards me, and as I did so the left bank of motors practically stopped, the quad flipped over onto it's back and nose-dived into the floor!
Luckily no damage other than two broken props, but what could have caused this? I have attached the IMU log if it will help?
Specs:
4 x Afro 20a ESC's with SimonK
4 x Turnigy Multistar 4220-650kv Motors
4 x 11 x 4.7 Props (each completely balanced to very fine tolerance)
HKPilot APM Mega 2.5 (Latest firmware from Mission Planner)
FrSky V8FR-2 Receiver with DJT Module for 9XR
Deadcat with Defibrillator
Zippy 5000 4S Battery

Bump, nobody got any ideas? :(
Interestingly, here is the Motor Log minus the props, just sat on the floor running the motors up through yaw, pitch and roll. Notice between Line 2900 and 3200 when I pushed up to full throttle that all 4 motors are turning at different speeds...
