Well for one thing, I just don't like YS engines no offense. And the SuperCharged engine that I bought, I have 100% confidence in because my dad had it before. The power also makes up for the weight. I remember Naruke using this engine in the 1999 F3A championships. I just love this engine for one thing is that it was the very first model airplane engine equipped with a Supercharger and probably the last.
Yes, it might have been the first (that doesn't necessarily qualify it as best though), and it may well be the last blower-equipped model engine produced.
Now ask yourself WHY that is. Why did it disappear off the market so quickly? Why didn't all the top guys immediately switch to it to try and gain a competitive edge over the YS's?
Weight, complexity, vibration, and expense do not a better engine make. If a heavy gear driven supercharged model engine were fundamentally a world-beating concept in pattern, OS (and everybody else) would be making them and people would still be flying them, most likely.
Just my 2c worth.
FWIW, my Excelleron 90 is going to be electrified this fall, most likely with a Hyperion Z4035 motor. I had bought a new MVVS .91 2-stroke and pipe (a stump puller of an engine) for it after I got the plane, but I think I've changed my mind, now that big LiPos are more reasonably priced.
