Cheers guys,
lets hope we can sort this out.
It calibrates ok with the Tx,
the car is a cat 2000,
with drag brake set to max and brake set to max neither of them work.
It just free-wheels.
After doing a factory re-set and trying to set the brakes again as per the manual,
still no brakes !

I have tried it with a 2.5 turn non sensored tekin redline and also a 6.5 tekin sensored motor.
