I'll nominate my Psycho III circa 2012. (sorry for calcuation errors) I had the privilege of flying a couple practice matches with Don Cranfill(God rest his soul) , probably at the 2011 NATS. We had a good match. I got a couple of quick cuts prompting him to something like "how'd you do that" and then came back with a kill. Don was very smart and experienced.
The Psycho III has a 54in. span, wing area of 540 squares. The aspect ratio is 5.4. The span loading is 0.5 oz/in. The wing loading is 0.41 oz/sq.in. The root chord
is 12.5 in., the tip 7.5. It makes for a pretty plane. It's big advantage is that with the high aspect ratio the plane bogs down less in maneuvers.
With a decent Nelson, which I still have, it goes well over 100 mph on 15% fuel and an 8/5 Apc prop. 28,000 rpm. Henry will probably chew me out! The only problem is the rpm starts to destroy the prop reinforcing. So after4-5 flights just bend the blade . If it breaks, throw it away. Looking closely you can see very thin flex marks building up around mid blade.
Just for a compare, at 16 oz. 340 squares- A meticulously built nemesis 39in. span Nemesis, very light, carries 0.047sq.in./oz The aspect ratio is about 4.5. The span loading .48-.5 oz./in.
The span loading, a measure of maneuver drag build up as the wing turns harder.
Just fix my arithmetic, please don't complain! I've had enough trouble last spring to last me the rest of my life!
