This cogging problem that I am having can happen at any thing, when starting from a standstill. From slowly easing on the throttle to jamming 1/2 throttle all of a sudden. It doesn't happen everytime, but enough to be concerned about it. The trouble is that when it happens during the heat of a race or bashing session on the track, I can't always tell when the truck is cogging. I mean that I can't tell if the truck isn't moving because of cogging or if it's hung up on something; and if it is cogging and I give it too much throttle to get going again after a wipe out, I fry the spur gear.

I also don't understand the part about lower voltage getting me less of an amp draw. I thought that given a particular motor, say a 1500 watt motor, the motor can generate the power that is built to generate. So, if I'm running a 1500 watt motor, it would need to draw ~101A to make 1500 watts with a 14.8v pack. If I drop the voltage down to 11.1v, then it would need to draw 135A to make the same power, so I'm thinking that dropping the voltage would make the system draw more amps. Am I missing something or oversimplifying something?

I'm running my system with the lowest timing, lowest start power, and 0% punch control. The punch control makes the truck undriveable on our track. Our track is very tight and technical.

I have noticed that the "problem" gets better and I reduce the gearing. I'm now running a 10T pinion and it's about to a point where I could live with it, but would rather not have to. I have't temped anything yet, but I ran the hell out of the truck yesterday and the esc was noticeably way hotter than the motor, so I'm going to assume that I'm still overgeared a bit.

GD, what gearing are you running on your truggy? I'd imagine that you are running proline MT tires. Maybe the crime fighters, bow ties, or holeshots.

On a side note, GD, you were kind of rough on Castle, but the answer that I got from them was complete BS. Until a very short time ago, I was an avid fan of the Castle products, but I'm starting to change my mind. I can't get support to save my life. I'd imagine that it's because they're devoting a lot of time to the MMM project, but what happens when I need support for the MMM and they're working on the next latest and greatest thing. Am I, again, going to be left hanging for support.

Of course, I still have to keep in mind that the MM was never intended to be used in an 1/8th scale application.
