Now that I think about it, the becs that I got had a magnet twisted up in the lead wire to eliminate interference. I wonder if that might have something to do with it.

Anyway, as I said, I did find that the lower I go on the pinion, the better the problem gets. I think that this shows that I do need to "go back to the drawing board" with this project. 13+ pounds is a lot of weight to get moving. I know that GD has his running pretty good, but I'll bet that his doesn't weigh anything close to 13 lbs. Knowing GD, he probably has his registering negative numbers on a scale. LOL.

I went and got a set of ofna 28mm offset wheels and some Bowties today. I glued them up and then remembered the 20mm lugs. Crap!!! I lucked out and found a set of those adapters that ofna made to turn a buggy into a truggy, in my box. I just popped the retaining pin holes in them on the press and turned them down on my lathe. Anyway, they (bowties) are considerably smaller in diameter than the stock Muggy tires. If all runs well with those, then I'm set. If not, I'll be looking into a 5S or 6S setup with a higher turn motor.

I also wanted to mention this. I put my setup back in my buggy. The MM/7XL that is. I put the 14T pinion on it and did an experiment. Nailing it from a dead stop is something that I've never done before with my buggy. I suppose that I just don't race or bash that way, but I tried it tonight. Sure enough, in about ten tries, on the last one, it cogged really bad and then stripped the spur gear. Pulled the 14T off and put the 10T on and no problems. I then pulled the 7XL and put the 8L in the buggy. Went back to a 12T pinion, which is what I usually ran with the 8L. No problems at all. Went up to the 14T pinion and it started to show slight signs of cogging.

Would going with a better controller do away with all of this non sense? I'm liking the Compro and the Quark 125b.

Thanks guys.
