wing tip A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of sha ...

. The wing has an area of and the cabin will be in width. The landing gear features a fully castering nosewheel and differential braking for steering. The aircraft has been designed for engines of . The manufacturer markets the design as "the only composite, plans built, 4 seat aircraft that uses a conventional - non canard - platform. It can be constructed entirely from the manuals using raw materials or from pre-formed parts."
