Right after a hard days work, and a hard nights work too I've finally had time to have a quick look over the car.
It's not a transmitter setting, it doesn't seem to be the motor (how much have you got to love the Speed Passion plug in V3.0 motors!!!) as substituting the motor for a known good one from the RB5 seems to make no difference.
All ESC settings reset again, still the same .... but a firmware update (to the one mentioned on another thread) seems to have, in the hands at least, sorted the problem. My conclusion is that I must have messed up the previous firmware update and just not noticed the lack of brakes at the previous meeting!
My LPF has worked faultlessly and has only ever been on the factory supplied firmware.
So there we go, thanks for all the suggestions but it seems it was a user error on my part (hopefully), not quite as big a silly as DCM's suggestion but my own fault none the less!!!
I'm still getting used to the brushless motors, as recently as just before Xmas I was seriously considering going back to what I knew, 20+ years of tuning brushed motors, but I'm getting there now and still hugely impressed with the Speed Passion stuff.
Hopefully it'll all be working properly for Friday night at Hereford
Thanks again to all those who took the time to offer assistance and share their experiences it's what makes the oOpple community great to be a part of
