The aircraft features a cantilever
low-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple wings.
A monoplane has inherently the highest efficiency and lowest drag of any wing config ...

and a single engine in
tractor configuration
In aviation, a tractor configuration is a propeller-driven fixed-wing aircraft with its engine mounted with the propeller in front, so that the aircraft is "pulled" through the air. This is the usual configuration; the pusher configuration ...

NACA 63A-214 airfoil
An airfoil (American English) or aerofoil (British English) is a streamlined body that is capable of generating significantly more Lift (force), lift than Drag (physics), drag. Wings, sails and propeller blades are examples of airfoils. Foil (fl ...

wing root
The wing root is the part of the wing on a fixed-wing aircraft or winged-spaceship that is closest to the fuselage,Peppler, I.L.: ''From The Ground Up'', page 9. Aviation Publishers Co. Limited, Ottawa Ontario, Twenty Seventh Revised Edition, 1 ...
, transitioning to a NACA 63A-212 airfoil at the
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."
