The Yak 55 is a sweet flying plane in all respects. At 102"" it's a 33% plane that would handle a 100cc engine just fine. It looks bigger than 33% at 102" though.

One of the composite versions with color will set you back almost $1,800.00 for the plane alone by the time it makes it to your door. There's really no reason for that other than the limited number of suppliers on the market and the "dealer reps" in the middle of a Comp Arf sale. If someone was to come out with a 55 in a 100cc size, that came in fairly light, and sold for under $900.00 it would move pretty well. If the average modeler was able to use the assembly skills they already possessed, and not be required to learn or understand techniques particular to fibergalss and carbon fiber, it would be better still. Does anyone have any idea how long it takes for high quality epoxies and milled fiber to dry? Then add in the number of assembly steps you get to do. Lot's of time expended that's not going to be with a standard construction plane.

The 55-SP looks and flys better than a 54.
