This Mamba Max didn't like me

MM, that's wild. I'm surprised that you were able to run the 18/46 gearing. We ran 16/46 in an 8ight buggy with a MM and 8XL and it kept stripping gears when on the track. It turned out that the system was cogging so badly that it would tear teeth right off of the spur. Had to go to 14/46 to stop the cogging.

I don't know what's going on with the Mamba Max lately. The very first two that i bought are doing OK on 4S. The three newer ones are with Castle right now. The very last one that quit working, just stopped. No smoke, no nothing.
