GM3 Comm problems
About 2 weeks ago, I was going to cut the comm on my fairly new GM3 for the first time. It had about 2 weeks of 1/12 scale racing on it, and I thought it was time for a fresh comm and new brushes. I just made a very light pass, and the comm started to split apart! 1 of the 3 comm "plates" allmost came off. The motor is junk now, which isn't the end of the world. Just wondering if I did something wrong, or if this is a common problem??? It's actually a Fantom GM3.

The Rage is a high RPM motor, but be sure to gear it right

I geared my GM3 too high, and it went poof too!
Probably what happened is that fantom cut too much off the comm, so it was too small in the first place.

Yeah, Send the comm back, hopefully they will replace it. I bought a fantom GM3 too, and they are nothing special. You are better to save 8 bucks and just get the GM3 pro from trinity. I have a dyno, and it wasn't close to what the numbers said.

Actually the Fantom P2K is better than the regular Pro, I was cutting .30s off my oval lap times just because I had a faster motor, and that was when they were both new...unless I just got a good one

I suppose $5 of the $8 is just for the Fantom Sticker. you're right, I think I am better just getting the Trinity Pro version next time.

The GM3 is natorious for blowing, i just always thought it was after 4 weekends of racing... not 4 battery packs

Troy, the MVP is pretty far from a GM3. It's a torque monster. It's no bulletproof motor either... Runs hot, and I bought one where one of the magnets had moved, and the motor was locked up. I've heard of other people having the same problem. I think it's been fixed since then, though. I've got 2 MVP's, and 4 P2K's. At times the MVP will be faster, and at times the P2K will be faster. So, I guess it would be worth picking one up, just to have it when you'll need it.
