[1] Apart from their undercarriage configurations, the XL (tricycle) and Trail (tailwheel) are essentially the same aircraft, with common layout, aerodynamics, dimensions and engine choices.

Fin and rudder are straight edged and swept but the cantilever horizontal surfaces are rectangular; the port elevator carries a trim tab.

[3] The flat sided fuselage is built around a welded chrome-molybdenum steel frame which is skinned with riveted metal.

There is a wide, upward hinged, starboard side glazed door for access into both seats.

[3][5] The Trail has a fixed tailwheel undercarriage, with the mainwheels mounted onto the lower fuselage on cantilever aluminium spring legs.
