Where have my brakes gone? Any help appreciated

[RogerM]

At Petit I was really noticing a lack of brakes, that is the reason I made the (completely wrong) decision to put a front diff in for the final … made the car handling not to my tastes but still with no brakes! This was costing me LOADS of time as I couldn’t stay on the power for the straight or else I’ve overshoot the “wall of death” and could only blip the throttle through the infield as if I built any speed I couldn’t get it into the next corner.

I am 95% sure that the brakes are causing the slipper to slip but will try locking the slipper up just to be sure.

Speedo & transmiter are still adjusted correctly for brake side EPA, set to 100% brakes, running a little drag brake (still can’t drive with a free rolling brushless motor!) and initial brakes set to the same as drag brakes.

When I jam the brakes on whilst holding the car the wheels don't stop immediately, only a small delay but the same speedo setup (but with a milder motor) in the 2wd car almost flip the car out of your hand.

The brakes on the same set-up used to be awesome!

Have I killed the motor / speedo and if so how?

Going to try another motor but don't have another equivelent (will have to be the 2 winds milder one out of the RB5) so may not be the best comparison.

Any help appreciated.
