Trouble calibrating mmm
 

Trying to recalibrate my mmm after using castle link and it will recognize full throttle but not reverse red continues to blink. I have done this a ton of times before.i even tried changing end points on my transmitter"dx3s". Any suggestions. Oh yeah i just downloaded the firmware.

Could be a firmware bug, try rolling back to the last version (Im still using the older versions as I dont believe in fixing things that run perfectly....).

On your DX3s, not only do you have to make sure your endpoints are at 100%, but your brake travel is set to 100% as well. Also, adjust throttle trim to 0.

Good call there were some errors when i downloaded the new firmware. I reloaded and now programming is working fine.
