Loosing power

[Mcisaacracing]

So I was running the truck today, after I warmed it up a bit it was doing wheelies non stop and had a lot of punch off the start. After running a tank and a half through it (non stop), with no cool down time it seemed like it was loosing power. Should I be letting it cool down between tanks? Would it be cause the diff oils are heating up and getting thin? Why would I be loosing power?

It is probably the spur gear unscrewing a bit. After you let it cool down, is it going good again? Probably not the diff oil. You maybe have a leak in the engine. Check for loose screws everywhere. The tuning of the Trx engines can also be a pain.

Ya it's good after it cools down. I've completely sealed the engine. Actually it's an OS.21

It could be wearing out, and when the sleeve expands it will get low on compression.

Best to contact O.S. about it.
