Well, for those interested in rather spectacular performance capabilities and a very precision airframe, I must recommend the Goldberg Obsession with DL 50. It's vertical capability is, shall we say, "sparkling". Although the DL adds a bit of weight beyond what the Obs is meant for, it has ample wing and stab area to support it easily. Floats on by, if you're not careful, and the big ol' 22" disc slows that baby down like a parachute.

The new DL 50 in her is just as reliable as the others, and it needs to be, as nearly all the flying is literally 1/3 throttle. I did a couple of full-throttle verticals, and the lookee-lous very quickly surmised that "it would go out of sight real fast".... Yup. Under-stated, that was....

It is a "first flip" restart already, and there is only about 40 oz of fuel through it. These can run on fumes on a 12 lb pattern-airframe, let me tell you.

There were no videographers present, so you'll just have to imagine an airplane that at full throttle will take about 25' to be able to pull off and go STRAIGHT up, accelerating.

Yeah, it's pretty impressive....
