Who Stole My Reverse??
 

I've had my crawler sat up for a while inbetween rebuilding the axles. Last night I put a new motor in I seem to have lost reverse. I'm running a Mamba Max and Revolver back and controlling it all with a DX3R.

So anyone know what could be wrong??

Did you remember to put the reverse screw back in? "thumbsup"

j/k

Have you tried setting up your radio with the Mamba Max again and verify that the ESC is program with reverse (could have some how got reset).

Everything seems to be ok. I just plugged it not my computer and it's set on brushless, Forward/Brake/Reverse. I've also been through my settings on my handset and all seems good there. I'm really confused.
I guess I'll try resetting it all and see what happens.

I dont know about the MMax but from general electronics if it hasent been fed power in awhile it may need to be completly reset. Give it the 3 finger salute!"thumbsup"

Try looking at the firmware page. Load in the oldest firmware to the esc. Then update to the newest. Then set all your settings, and try it. I had to do this to get mine to work, it just stopped doing anything one day.
