I've flown the stuffing out of a World Models Air Combat Zero. It's not much to look at, stand way back and take off your glasses scale, but it flies great. They make a couple other trims. Over the course of its life I've had a Saito .45, OS .25F ABC, and an OS .32 FSR in it. All three flew great, but the .32 is in it right now for the speed. If Iever crash it, I've got a Yak (exact same plane, different colors) that I'll put in service.

The Great Planes combat series get pretty good writeups. I've thought about buying the Spitfire, but with somewhere around 30 unbuilt ARFs and kits sitting on the shelf, Ineed to resist the temptation.
