# Can't set up the Throttle/ Brake end points with DX4S Radio

When I tried to set the Throttle/Brake end points for Xerun SCT PRO combo it wouldn't let me program the full brake end point with the new DX4S Radio.

The ABS function was enabled from a previous car I tried it on. I had to disable this function first.

After turning off the ABS function I was able to properly set the Throttle/Brake end points on the ESC.
