Suzuki probably was going for a low fuse loading. Essentially the same thing as blowing up the fuse. I guess you could sit down and calculate resultant forces and all of the fun physics and aerodynamics to see if a smaller, albeit lighter airplane with less fuse loading will have better crosswind/knife edge performance than a larger fuse on. I imagine they're similar, however Suzuki, being a top level F3A competitor, likely designed that just for his tastes and played on a crazy idea he had.

I too ran the 1.40RX for the first two years of my flying pattern, and it was literally a fuel, flip, and fly motor. I think that's where I got most of my flight time, as it was cheap, easy to run, and reliable. Great motor, I've got two sitting here that I need to get rid of, as I likely won't be using them ever again, but I really enjoyed them while I flew them!
