Kougar
I'm in the middle of building a Kougar right now. Did you beef up the firewall? The stock one looks kind of flimsy for a hot engine. I'm going with a Rossi .40. I've been thinking of using at least 1/4" Ply with the 1/8" backing. What do you think? As far as the props, I'd start out with a APC 9X8 and fine tune from there. The Nova Rossi should have no problem with that. Let us know how it flies.
