Hey Redcat enthusiasts, I just got my Volcano all cleaned and ready to run, and put in a new piston and sleeve for the Hyper .21. Got her running smoothly and impressed a few girlies at the park Finished building and installing my custom Direct drive made from an old 47T 2 speed spur gear and a 51T Savage X spur gear. Clutch bell was a 12T from HPI. This combination equaled GOBS of torque upon take off with stock speed. With huge 6 inch tires, heavy suspension, and a big block, that's not bad. Wheelies anyone?







Then the inevitable happened. There was "so" much torque, the stock one-way bearing that came with my two speed totally shattered. Upon closer inspection, it seems the stock Redcat one-way bearing was made of plastic; no way near strong enough to handle the power of the engine. So I replaced the old with a used yet much stronger, full steel one-way bearing I found in my blown HPI 15FE motor. It was a perfect fit and fit nicely in the stock location.

Nice dude, that would be sick to throw a big block in mine, i guess thats why i got an 1/8th scale haha. Is that a booster bottle?

Yeah, made from a sharpie. lol

Haha, did it make a difference?

Haha, did it make a difference?

More stable idle, slightly better gas mileage. Not sure if there was a boost in low end, but I'm guessing very little.

That would be nice, what did you do just tap into the block next to the carb?

For this particular engine, there is a hole already tapped into the side of the block. It comes factory with just a screw in it; remove the screw, screw in a fitting, and done. Other engines require drilling and tapping just below the carb.
