My Brodak Buster is a hoot. Built up light with the very good wood in my kit. An all time fun plane. Powered by a fox 35, it should be fairly mild and forgiving. Mine turns tight and is stable. Power is a honking Tower 40 run fast. Turning a 10x4 something like 14,000 rpm. Ridiculous plane. Our fun loving top 20 flyer laughs a lot when he flies the Buster. Can't get enough of it. I hear the monokote shriek as he turns some wicked corners. He always talks about how it won't slow down, no matter what you do. I still have a Fox 35 CG Buster built thirty years ago. It turns tight and is a mild flying sport plane. I hope to do another Brodak Buster at some time. Legal in Foxberg the way yours is setup (with a Fox). If you run into a Foxberg guru they're liable to bend your mind with stories of these engines turning high revs on smaller props. A well broken in Fox 35 will turn high revs. True. Usually just before the crank goes ping and snaps. A fox 35 Buster is legal in foxberg, something to think about.
