Wow. That's' the most-intact, best shape Eaglet I've seen in years!Interesting little project!
American Eaglet motor glider - aviation - by owner - airplane...
I looked at these a lot, once upon a time, because I wanted one. From what I heard and read, my understanding is that stability is "weak", and there have been reports that the roll-control power provided by the "spoilerons" can be deficient at some corners of the flight envelope. It's one of the group of aircraft designed to the "sustainer motorglider" fad of the early '80's (The Haig Minibat was another, and a direct competitor to the Eaglet), so while I believe you technically can take off and climb out with the little 12hp McCullogh engine on a cold morning, it was really meant for "saves" and the airplane was intended to be aero-towed for takeoff. IIRC, L/Dmax is about 23:1, about the same as an SGS 2-33. I don't think I ever knew a minimum sink value.But is it a sound design? I don’t remember what I’ve read about them.
seems from what I read that is a generous characterization. add ailerons a stronger engine/prop and do not fly over 3G stress and it might be ok.stability is "weak", and there have been reports that the roll-control power provided by the "spoilerons" can be deficient.
That'd be a complete wing redesign, unfortunately, both aerodynamic and structural. The problem with a "stronger engine/prop" is that the diameter of the propeller is tightly constrained by the wing and the ground. Folding multi-blade propellers are rare as roc's eggs, and priced at their weight in gold-pressed latinum.seems from what I read that is a generous characterization. add ailerons a stronger engine/prop and do not fly over 3G stress and it might be ok.
The one I saw had a homemade folding prop.....basically 2 " U fittings" with a bolt through the root of each prop blade. I think it was not even spring loaded closed, Centrifugal force opened the blades and wind closed them when shut down. Very simple and should work if the stress analysis on the parts is correct, and you can build and balance accurately.Folding multi-blade propellers are rare
YEP -- i immediately pictured that seat ; getting replaced with one...
You can, for example, see the (leather, in this case) sling seat in the photos of this one for sale. Meaning the seat is just a sling of material to keep your butt off the fuselage bottom. No seat structure at all. The pod structure is a strong main bulkhead under (and attached to) the mainspar, with the engine hung off the back and a few light tubes going forward to hold the (largely non-structural) fiberglass aero fairing around the pilot. The tubes are aluminum, pop-riveted with gussets, similar to the SuperFloater. Crashworthiness is almost zero, typical of ultralights of the period.
It's a neat design in concept, and there's room for a beefed-up, slightly larger, better-designed knock-off in the ultralight sailplane/motorglider niche.
Billy do you want a decent shaped glider pod to make a mold from... without driving from !)(#*$ Vegas to !(#*$ Charlotte???I E-mailed the guy and told him i wanted to mold the pod, a
is already shaped
and waiting for me to mold it.
