Ok. I am at work away from home and from the pile of wooden slats that should become my airplane.
I have a lot of time to think and every now and then an idea comes up again.
Premise. In Europe the rules on ultralight planes are much more permissive, as far as I know, than in the USA. I think similar to Canada.
In Italy we have a maximum take-off weight for two-seaters, of 450kg (990lb) plus any parachute and equipment such as floats and life jackets. Elsewhere this weight has been brought to 600kg (1300lb) and in fact all the ULMs in production belong to this category.
In addition to these weights, variable pitch propellers and retractable landing gear are allowed.
On the other hand, some of the most beautiful and iconic planes have been born in the USA since man began to fly.
Among these, in my opinion, one of the most beautiful is the Beechcraft Model 17 Staggerwing.
Now here's the idea that sometimes keeps me awake at night. Build an aircraft that is as close as possible to the Model 17, but falls into the "European" ULM category (and possibly in the American sportplane).
The engine could be a Verner radial, 7 or 9 cylinders. I love wood but maybe a steel tube fuselage would be more suitable for such a project.
The seeds on a biplane are always a lot of stuff to build, but why not think of a solution similar to that of Avidflier and Kitfox? Plywood ribs threaded on an aluminum tube. Possible carbon fiber D-tube as leading edge. Wing cables and strus tubes should help a lot in making everything stiff. A manual or pneumatic retractable landing gear would make everything beautiful, not like the original, but enough to make you dream of being back in the 30s.
