# Do wings on a plane need to be in the same plane horizontally, or can one wing root be 6" lower than the other?

Do wings on a plane need to be in the same plane horizontally, or can one wing root be 6" lower than the other?

The proposed application would be for a ultralight with high mount folding wings, where first 50% chord flaps would fold down 180 deg underneath the wings, reducing the "folded chord" to 50% of the full wing chord. Then the tapered wings would scissor back about 120 deg over the fuselage and interlock like a scissor, so when the wings are folded up, they are roughly mirror the same shape as the fuselage. One wing root would be about 6" higher than the other.

For example, with a 12" high spar root, and 3" thick wings, one 1/2 span would be mounted near the top of the spar, the other one, at the bottom on the other side of the fuselage

• "50% flaps" means that the flaps' "width" is half of the wing chord, not that the pilot has commanded the flaps to be deflected halfway, right? Commented Oct 8, 2019 at 21:47
