RAGII,The RCM plans service has alot of so called 1/2A plans, but their selection could use some updating and weeding out. I think the best choice for a fast flyer is a GLH. The DNU by PTULMER is a great sporty flyer. If you want to go 3D, scratch build a HalfWit. Look in the RCU thread archives for it. Matchlessaero is the author.
