mamba max 1.2 and no reverse

[auto2]

i updaated firmware on my mamba max from 1.7 to 1.20 and i lost reverse.

i have it set for reverse with the 2 sec delay. the light on mm lights up when i hit rev but thats it.

everything else seems much better. smoother less coging,

i rebound the spektrum and reset the raadio. 3pk

if i switch setting to fwd brake rev then i have rev. just no rev with the delay
