Re: questions on multi-wing planforms

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.

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)."
