Firstly, I am new here although I've been reading for a few days. For
anyone with more knowledge than I, I keep considering building a small 4
wing aircraft. Not stacked, but two up front and two in the rear. I
have read frequently of problems supposedly resulting from interference
of the airflow between wings, but I can't seem to find anything very
specific. I'm fairly confident that interference between the front wings
(or rear) can be minimized by reasonable spacing and differing dihedral.
I'm not sure what the effect of the airflow coming off the front wings
will have on the rear set. I don't know whether I could remove most of
the problem by having one set considerably higher (how much?) than the
other set or if it is reasonable to have them on more or less the same
height. The reason for the concept is trying to get a wingspan small
enough to fit into a normal garage and conceivably take off and land from
streets and highways. I visualise something in a two place plane that
would fall into something of the appeal category of a motorcycle or small
sports car. Any thoughts would be appreciated.

Go from 4 to 1.
The Dyke Delta JD-2 will fold up to fit in a one car garage. And it is
designed to be towed behind a car on it's own wheels; though, some have
had issues with getting trailer tags to do it legally.


I'm familiar with the plane, and it is reputed to be very difficult and
lengthy to build.

Aren't they all? 4 years and running here. Almost ready to close up
the skins.

instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
