[B4 Sloth]

I know there have been several posts on this.

I used the losi brushless system last year and could not fault it. However yesterday was my first race of 2010. The losi failed me.

For some unknown reason was all working fine when it suddenly stopped. Motor not hot, esc not hot and only 20 seconds into race.

The orange light was on and stayed on. Servo would turn but no throttle. It would not reset. Today went out to try it and now i am able to get power to wheels, however it is only 'full power'.

It is all or nothing and will not move at slower speeds at all.

Sensor wire tested and ok.

Any ideas?
