I'm a proponent of leaving B class alone for the guys that want to churn and burn. I'm also tired of exploding an average of 15-20 airplanes a year. I was one of the instigators of SSC combat. Since last June, I've built 3 SSC airplanes, and they have all seen monthly combat and are all still flying. The origional Spad HOR has been averaging a mid-air per round (that's at least 16 mid-airs) and it's still going. That's why I've gone exclusively to SSC for RCCA combat.
