If too hot then start dropping teeth from the pinion and test.
- battery going off
- are you using comm drops ? These can give a punch for the first few laps and then "wear off"
My guess would be overgearing. Very common.
I went through each one of these to trouble shoot the problem:
Gearing is set around 5.0, same as the rest of the racers... tried changing, and still resulted in the same problems. I thought of overheating first, which is why I ran to check the temp after running it and it was around 90... strange huh!?! the battery was replaced, same problem. And I do not run comm drops. Is it possible that the engine was gummed up? If so, what's a good way to give it a thorough cleaning.. or should I just toss it away and spend $17 on a new one?
