Piperchuck - My Small Supra Fly was an ARF (I was a kid) and I flew it, oh, maybe 200 flights before a radio hit-
Loved her, had an OS-28FSR (or "F") in it, can't recall---
I've heard alot of good things about the plane. Bought it not long before I took a long break from the hobby. It's on my short list to build, but not sure if it's at the top. Got to decide if the next one will be sport (such as the Supra Fly or HOB Chea pass stick), speed (Shrike 10 with K&B 3.5cc, Hiperbee with a .15, or GP F-15), or scale (Midwest Clipped wing T-Craft, Marutaka P-51, F4U, Little Half, or several others). So many decisions...
Meanwhile, my new WM P-51 is ready for its first flight and the wife's nagging me about building some cabinets.
I think OS had dropped the SR by the time they released the 28F. I can check the engine chart tonight. I've still got one, with a heli head. Great engine.
