The Brisson is a good strong engine though. I think it would fly the plane pretty well honestly. The BGX just made a guy fly the plane a little more carefully was all...take offs nice and long and landing throttle a little more important. Once the gear are up, no worries. The firewall distance requires an engine on the shorter side unless you recess the firewall of course. The G62 is a lot of engine for the plane, it doesn't need that much for sure.
