RE: need a plane for summer
out of the three 30-40 sized funflys i'd have the Cougar.
sounds like your after just a hoverer and a bash about one at that, i'd still go with a Cougar if you want to spend cash, or a SPA3D if you want a knock about fun machine.
once you go up in engine size you start taking the pure fun out of things unless you've got money pouring out of pockets
