GD,

I believe that what I'm experiencing is different from what you are with the Neu motor. I believe (for what it's worth) that you are experiencing a "communitcation" problem of sorts between the motor and MM. I think that what I'm getting is a case of the motor expecting the truck to be moving and it isn't. When mine cogged that last time, violent is an understatement. I thought for sure that I had cooked my MM. It did, indeed, strip the spur upon cogging.

I'm running 4S lipo, and I don't think it's the battery. I was running a Kokam 4800 pack and it is a beast of a battery. It'll dump current at will. I wish I had some sort of data logger so that I could see what's going on. All I do know is that with the same gearing in my buggy, the problem (cogging) is almost non existent. I hope it is just that my tires are just way too big for the gearing. It must be like running a 20T pinion in a buggy.

The funny thing is that my buddy was doing the same thing (stripping spurs) with his 8ight. We had just assumed that rocks were eating the gears. We were running 16/46 gearing, but he was having more of a cogging problem than I was. He never did try a smaller pinion because he liked the performance. I wonder if his internal diff ratio was different from mine. On the track, his buggy with the 8XL running 16/46 was equally as fast an my buggy running 14/46 with the 7XL. Coming into the straight, it was really a matter of who got out of the turn first that determined who was first at the end of the straight. In know that he was running a slightly larger pinion, but I don't think that two teeth should have made his buggy that fast.

I'm hoping that it is just the gearing. I'm waiting for the postman right now. I hope he has my pinions so that I can try a 10T with the 44T spur. Better yet, I hope that my order from Mike comes in too, so that I can try the 10T pinion with the 46T spur.

If that doesn't do it, all I can assume is that I have a bad connection someplace, although I went through everything with my Fluke DMM and did not detect any measureable resistance. I do remember that when I soldered the 12 gauge wires onto this particular controller, my 700* tip for my metcal was on its last leg.

BTW, considering the size of the ground plane on this MM and its heat sinking ability, I wonder if going with an 800* tip wouldn't be better for soldering on the wires. I don't own a tip that gets that hot, but I was kind of struggling with the 700* tip.
