Motor setting on MM controller

so i guess i have it programmed correctly, i never used reverse for setting nine. I also ran across another problem, which I think I solved by calibrating full throttle, brake and neutral. Before I re-calibrated, under acceleration the truck would abruptly brake, spitting tiny pieces of kyosho spur everywhere. This is not cool at 20+ mph. What gives? I assume the reason is that I did not have the brake properly calibrated? Thanks.
