Je finis un jeu en utilisant mon expérience du deltaplane comme fond. Au fur et à mesure que je recueille des informations dans ma recherche pour le jeu, je vous donnerais plus d'information. Je suis désolé que ma mémoire ne soit pas parfaite concernant mon produit. L'ingénieur d'études était Carlos Moralles. John Reisig


The Aolus was the first version of this planform from Spectra Aircraft. It had an extremely wide nose angle to minimize spanwise flow and maximize span efficiency. The tail was added to provide for pitch stability which would be lost due to the minimal sweep in the wings. A double surfaced, internal crossbar design followed, called the Sonic.

I had a lot of fun with my Aolus (was it spelled Aeolus originally?) I heard it described as "pitch weird and yaw funky", but I like that. It may have been Carlos who told me that tests had shown the washout tubes to have no needed pitch effect, but that they were put on for pilot expectations. Perhaps I flew without them, I don't recall. Assembly was flat on the ground, with tricky ways of getting that high tension sweep cable/bow sprit in place.


I had many wonderful adventures with my Aolus learning cross country in Owens Valley in 1981. It was the second prototype. Carlos Miralles taught me to fly it off Cuesta Ridge in San Luis Obispo, California, and sold it to me for $500. After many hours, I took it to John Reisig at Spectra Aircraft who sleeved its already massive frame it and smoothed out the leading edges. It was a superb thermalling machine. In a strong, smooth core, you could push out past stall and flat-spin at 2000 fps. Unique and unbelievable. With that reflexed tail, it gave you a very secure feeling that it would recover from going over the falls in violent thermals. And fast landings in high-altitude-density air were helped by that bowsprit. When it dropped, you'd fly through the bars and hit the sail (no keel). My buddies who flew their Aoli in Owens Valley were Carlos, Bob Dunn and Mark Hanley. But the thing that made the Aolus such a great thermalling machine, that huge tail, may have kept it from attaining the best l/d between thermals. After I'd moved on to Comet-clones, I loaned it to Bill Dodson around 1985 and he made its last flight from Horseshoe. See for more details.

Of course, the Aolus had a keel. I meant to type "no crossbar."


Hi everybody , I am inquiring from Italy and would know if anyone can help me in finding a copy of the original construction plans of bow sprit gliders like Spectra Aolus , MosquitoUP, Stratus, etc.

I have in mind to work on the construction of a bow sprit glider similar to all of the above mentioned gliders but with many updates in aerodinamics.

Your help will be much appreciated
Best regards
