I have made a small (1/2A) version of something called "QUICKIE"

It has a canard and main wing -- all with a constant chord across both wings

Canard -- 25.125"
Main wing -- 26.5"

The canard is low and the main wing is shoulder.

I get a wobbley back & forth at slower speeds

Q) Could this be due to the CONSTANT chord?

Q) Could this be overcome by tapering the wing ribs?
