This topic brought back some really fond memories.
I've always been a fan of biplanes but I never built one.
While designing subsystems for Augusta Helicopter in Coscina de Costa, Italy, I met up with some incredibly skillful modellers from the Aeromodellisti di Monza.
Among them, a true gentleman, Luciano Compostella. One of his favorite designs was his Falco (Falcon, Hawk) biplane. Powered by an OS Surpass 48, it flew an absolutely beautiful pattern and garnered him quite a few awards.
Speaking about the design, he mentioned that there was no incidence between the two wings and none between the fuselage and wing(s).
As I recall, he built two Falco bipes but I'm not aware of any differences between the two.
He also gave me plans for the Tango, Lampo and Falco. In the diagram posted by Steve Dwyer, that's me (bob) in the lower right corner.
This freindship between Luciano and me inspired me to design and build my Staggerwing Beech 17, which turned out be be an outstanding design.
Yes, I plan to build a Falco but since I don't have a Surpass 48, I'll us an ENYA 46.
Luciano and I became close friends and I was truly saddened by his death.
If anyone is interested in the Tango or Lampo, I will send full-size plans - just cover my expenses.
