I don't have the problem when taking off from a standstill, it's only when I used the brake to come to complete stop (no motor movement at all) and then try to go forward again. And even then, it only happens sometimes. I have been able to come up with a specific action where it is perfectly reproducable.

Since I'm using the MM in a small, lightweight truck, it recovers fairly well. However, using it in a relatively heavy buggy or MT exacerbates the problem since the ESC will have a harder time to get the truck to move due to load and motor size.

Personally, I think it's just a matter of the motor position sensing algorithm. If CC could recreate it, I have confidence that they could release an update to solve it.

Believe me, I'm all about sensorless designs, but it's issues like this that give sensorless a bad name. It has to be something specific to the MM, because my Quark doesn't do this at all (I tried it).
