Well I guess if you get into an upscale 28% you also have to jump up the servos, batteries, etc. Let's be honest, the greatest thing about this engine is the price so if folks can find a way to deploy it inexpensively all the better. I can see both points of view and have stated my opinion on the choice of planes but it's Paul's choice. He's the only one that has to fly it. You do however need to be careful. We have a guy at our club that loaded the batteries in the tail of an ultra-stick to compensate for an over-sized engine and when he pulled up from a blender the fuse broke just forward of the batteries. Luckily everything stayed together enough to get it on the ground but only by the skin of his teeth. Let us know how it turns out Paul. BTW That wing loading thing should be used to see how well an airplane will fly, not IF an airplane will fly.
