Little Wing Autogyros LW-5

lw5


After the LW-3, the next logical step was to develop a two-place version. The prototype, based on the LW-2 and LW-3 single-place models, is a shortened version of all models. The original fuselage was designed for using an elevator for longitudinal control and, therefore, was built longer to provide ample control power at all flight speeds. With the direct (full tilting head) control, the full length fuselage isn't required and the shorter version will be much less likely to receive damage to the tail from a rotor blade during ground operation. The horizontal tail area has been increased accordingly. Plans were available for this version. The prototype two-place, short-version, has been test flown and should be in a cosmetically completed state by early fall, 2000. It features a Rotax 914 turbo-charged engine of 115 hp. It is very smooth and very quiet.
