The less blow by on the ring will make the engine run smoother. That's straight from Frank Bowman himself. We had seen this on a mintor 60 that had huge piston clearance.

Bowman rings on NEW DA engines?

I see that ThunderboltRC is selling new DA60's &DA120's with Bowman rings installed. Why? What problem with DA engines is this trying to solve?
