Retesting my 4s ZMR 250 - a raw lipo

After blowing 2 LittleBee 20a ESCs and my pz0420m camera, this is the first few flights (my 4th lipo, but they only go for 3 minutes) on this quad. It's got the same LittleBee 20A ESCs - I simply replaced these as I think I have a reasonable understanding of why these blew, but the camera is now an HS1177 as I thought it may be easier to vary my tilt.
Well, it needs some tuning - looks fairly good at low speed, but gets some oscillations at higher throttle. I had thought TPA was not in use in the rewrite PID setting on cleanflight any longer, but I couldn't see that in the docs, so I'll have a go at messing with that.
Despite the odd wobble at high rpm, the quad feels very locked in and is a joy to fly :) Must get some more 4s lipos, I've only got 4 and you burn through them pretty quickly !
