Hi guys, thanks for looking at this.
Generally if the ground is flat enough that all of the motors spin up evenly when throttle is applied, it will take off without issue and once in the air it handles without any problems. It's just if the copter is on anything from about a 5 or so degree lean that I have problems, and even then it's not something I can predict. Sometimes it will lift the lower side up, and then take off OK, and other times, it will flip towards the high side. I take off very very slowly and try to get all motors spinning before giving it any significant throttle as a result. Normally if it flips once, it will flip again, so I generally power cycle it if it flips once.
I've only ever taken off in manual mode.
I've got a log here which shows a tip onto the high side at takeoff, but yesterday I reworked the FC platform as I think when the dome was fastened, some wires were transmitting vibrations through to the platform. I think that vibrations are where pretty much all my autoquad problems have come from. I've only managed to get one flight in since then, and I took off from a perfectly flat surface for that one, and it flew ok. I guess the next few flights will tell as to whether this change has solved the problem or not.
309-AQL shows the flip, and 311-AQL is the flight after reworking the equipment platform. The equipment platform which holds the FC weighs 150g and is attached to the rest of the frame with four small 1cm square pieces of latex foam. I use motors 0,1,2 and 7,8,9.
