When I was into RC I had these...its basically a flying wing design...one big airfoil with a controll surface or two. They are made out of a nearly indestructable foam. Which means..."DOGFIGHT'S"...you try and ram one another and pull out of the ensuing tailspin!
With the ocean breezes in that area, get two of these and get ready for mayhem! Harness the winds power and go at it...
