Both of these were twin engine, V-tailed amphibious aircraft, the latter differing in its hull design, undercarriage and maximum take-off weight.

The amphibian is a cantilever high-wing monoplane with straight tapered wings; most of the sweep is on the trailing edge.

Its twin engines are placed above and ahead of the wing leading edge, as close to the centre-line as the clearance between propeller and fuselage allows.

The cabin is under the wing, with two long continuous transparencies, one on each side plus two shorter panels in the main entry hatch in the rear roof behind the trailing edge.

The LA-8's T-tail has a slightly tapered, straight-edged, swept fin with a sub-fin extension; both the rudder and the single piece, externally mass balanced elevator have electrically actuated trim tabs.
