Les, who cuts cores for the big Genie and the LT/S, sent me a set of his proprietary cores to try out. Having nothing going on the workbench at the time, I bagged the wing and mounted it on an LT/S fuse I'd built with a saddle to fit it.
Being proprietary I can only tell you that compared to the Genie airfoil
blend, this one is thinner, flat bottomed and lower camber with 128" span and about 1025 sq. in of wing area. Les said it would be fast and have a very, very flat glide.
Yesterday at 57 degrees and today at 67, it was unseasonably warm to provide a
chance for first flights. I used a short high start.
After a few hand glides I put it up. It went straight up, really too steeply, so I've moved the towhook forward a little.
Les's claim of good legs and a flat glide were right on and it is a nimble and responsive ship. With the flaps fully down it tracks very nicely and is so easy to land. I do see that, as expected with the thinner airfoil, it needs to be kept level and moving right along to handle best, rather than being flown on the point of stall.
The all up weight was only 69.2 oz. for a 9.72 oz. wing loading. . . .too
light for me for this much wing area, but it sure slows nicely for landing. For windy conditions, it is a good candidate for some interior ballasting with sheet lead along the fuse sides or bottom.
In any event, this one deserves more usage than it would get in my hands. I'm just too happy with my big Genies and regular LT/S's.
On request, I'll e-mail a sheet of information about it and group of pics. Airframe price will be $695, not counting servos or shipping.
