RE: REVO 3.3 engine noise
Found the problem. The bearings that are at the hub up front are making alot of noise. I took the engine, boxed it up and it's off to RB Mods for their custom work. I am told that 90 MPH can be had with the 4-tec with that 3.3 Traxxas motor after he's done. He guessed about 30K RPM's is what the stock 3.3 is turning but with their mods, it will be more like 60K[X(] RPM's and then that beast will fly. He said that they make a custom rod that will "NEVER" break too so I am happy about that as well.
