I havent heard of this engine, the OS RZ 21:

Has anyone used it? It looks good anyway.

How does it compare to the vz-b?

Ya i have heard of it but my hobby shop was tring to talk me into to getting it for my next engine. But i didnt want it i dont want to spend that much. But i heard that if you want to be reallly competitive this engine is the way to go. The guy that races at my hobby shop has it and it is the fastest motor at the track if you tune it right.........Nick
