How does the Cox K.B, with it's 1/2 inch of sub piston, handle a throttle ring? And what prop does it like for general use?

I use a 4.2x4 on mine, but it over-revs with that prop. The 4.5x4 would probably be best.

I would expect it to be sluggish to throttle and you would have to come up with a compromising mixture setting. The KB has a huge intake runner. Who knows, it might work OK? It would only take 5 minutes to find out.
