Its a big block case with a shorter stroke. The bore is simillar to what some of the .21's are running now.

Curious? ? ?

With the type of tracks here in the US Im curious to see if a smaller engine is the right way to go about it.

We have a lot of big jumps that I feel needs the power to complete.

Would indoor racing benefit? I would assume that would be a great fit.
That and tracks without long straights that need reving to the moon.

Is it ROAR/RC Pro Series legal to run a smaller engine?

The rules are just an upper limit.

On REDRC:

Quote:
O.S. Speed have released their latest 1/8th buggy engine, the small block 19XZ-B. A 3.1cc engine, it produces similar power to the 3.5cc version, delivers the power smoothly but most importantly gives much better fuel consumption than the larger displacement engine.
It says smallblock.....

I agree. I think the indoor scene is where this might shine but then again the tracks that are small and tight that have a ton of really low speed corners this may not work that well cause it has less power. It would definatly require you to be a smooth driver to get the most out of it so your not loosing speed.

The RC Pro Series site says .21 only, and ROAR rules say .21 Open.

IMO having a displacement limit is one of the stupidest things to worry about... We all know the bigger engines are no faster on the track and are usually slower....The only thing that rule does eliminate any of the manufacturers from putting any serious R+D into the bigger engines

By that they mean that you are open to anything up to a .21 and any .21 that you can make work in there. If you find a .21 that make 3.5 hp then you can run it. The rules for truggy say .28 open but 99% of truggy racers run a .21 because it is better on fuel and is just as fast. in there class.

I agree, I'd like to see one run, I was just curious on the rules.
