BL Mammoth......but no brakes.

[rcjmaxx]

Ive just converted an XTM Mammoth monster truck to brushless.Because its a 2 speed and i dont have a 2 speed pinion gear,Ive mounted the motor so it drives the larger of the 2 spurs,the 65t.But the problem is that i have forward but no brakes or reverse.Ive tried programing the 9920 to forward and brake with no luck.Ive done nitro to brushless conversions before but never with a 2 speed set-up,am i missing something here? Thanks
