Got this flying at last ,and it flies beautifully! One wing panel is warped ( old, secondhand airframe, not built by me ) I'd cranked up one aileron to offset this warp which was worrying me, but no need to worry. needed no aileron trim at all, just a few clicks of down trim. The 4S2P 21700 Molicel P45B's provided plenty of power for 2 flights, 10 minutes each.

First flight, the home built Arduino BLE33 board worked great for headtracking, on this flight, the second has a peculiar glitch, where it occasional jams over to the left, which made my FPV flight 'interesting' to say the least..

I'll get on to fixing that, but the 03 video footage, is really exceptional.

Let me know what you think in the comments.
