For a tiny quad like that, turn your Rate Roll P values way down. Try decreasing in 25% increments.

Thanks Chris. I realise that I might have been a bit shy on the decrease of this PID. I'll try that, together with the RATE_PITCH_P I presume. Tx

I have the micro hex - and found it is a real difficult one to tune. Rate_P has to be < 0.100 and Rate_D about 0.005 IIRC.

Try following the tuning guide, and if you can install SimonK firmware on the ESCs, or BLHeli if they aren't AVR.

I got back to my small tiny micro-quad and managed to get to a reasonable balance with the following parameters:

RATE_P: 0.03

RATE_D: 0.005

I would have done some more fine tuning if my flying skills had been better... unfortunately a pretty hard landing on the side had the final word : chassis broken... :-(

Thanks all anyway, it's been a very useful tuning exercise in any case!

Cheers
