hello,
My 3.3 lost compresion and I'm looking for a motor to run in the winter (indoor track). psunitro has a OS . 15 for $25. Would that be a good engine? Then ill send my 3.3 in for the summer. Let me know
RR21
Hard to say, but it'd be best to ask him, he won't steer you wrong.
Without knowing what model number, if it's bump or pull start and the like, I can't say. It may require a different mount to put in your Revo.
Are you sure your engine has lost compression? Isn't your Revo relatively new? If it's still under warranty and you didn't run the engine lean, Traxxas will likely send you a new engine for free.
I don't know of an OS 15 that will fit in a revo easily. The revo requires a rear exhaust engine and a slide carb to work easy. The OS 15's are side exhaust. The header would be smashing into your shocks. At least without some serious modifications it wouldn't work quite right.
Just get the 3.3 pinched by osrocket or rayaracing. $20 gets you going again.
