I personally did not built a crawler out of a nitro. But my buddy has. He used his traxxas revo. Lifted it and put 2.2 wheels. And some other stuff. Got pretty hot thats all i know. I know that this isnt much info, but hope it helps. rick-out

Nitro's need speed and airflow to keep a cool head (all puns intended :lol: ), they don't do well under load with no airflow. I've heard of a few nitro/electric hybrids, but as Rick said, still had overheating issues.
I used to think I was indecisive, but now I'm not so sure.

wouldn't the clutch be an issue for crawling? as it it would explode?

There is that too, though I don't know that it would explode, just not lock up tight enough to do much. On my maxx I filled all the friction peg holes and cranked the screws down tight and it still wouldn't hold for even mild crawling.

Maybe an engine and tranny out of a Nitro blizzard and gear it down more. It would still probably be pretty harsh throttle response.

Nitro engines have a power band just like any internal combustion mill.. They have to build up their torque through RPM's and these little two strokers will just get too hot.

Not to mention you'd eat clutches like popcorn, always having to ride them between slipping and gripping- all the while trying to keep your motor wound up enough to produce power.

I think there is a pretty good reason why you don't see very many dedicated nitro crawlers.. They just aren't good for it.

You can gear it down as much as possible and it will run over things but a nirto will not crawl! Crawlers have a top speed of about 5 mph...you will never slow a nitro down that much.

First gear on a nitro blizzard is pretty darn slow.
