Lederlin 380L
# Lederlin 380L

The Lederlin 380L (marketed in North America as the Ladybug) is an unconventional light aircraft developed in France in the 1960s, and marketed for homebuilding.

## Development

François Lederlin developed the 380L from the Mignet HM.380 "Flying Flea", and eventually created a new aircraft sharing only its choice of wing profile and general configuration.

Like the Pou-du-Ciel, the 380L is a tandem wing design, with the forward wing mounted on a set of cabane struts forward of the cockpit, and designed to pivot in flight, to vary its angle of incidence. Otherwise, it is unlike the original Mignet HM.14, having side-by-side seating for two in a fully enclosed cockpit, and a neatly cowled engine. The fuselage is of steel tube construction, metal-skinned at the front and fabric-covered to the rear, and the wings have fabric-covered wooden structure. The tailwheel undercarriage is fixed.
