|LS-4b - Standard Class Sailplane|
The LS4-b is one of the most successful sailplanes. It has been in production since 1981. Over 1000 units have been built, and they are still in production for this very popular model.
Development of the LS4-b was influenced mainly by technological and aerodynamic knowledge based on the 15m flapped LS2 and LS3. The resulting sailplane offers a wide range of possibilities for contest pilots and clubs alike. Most remarkable are its excellent flight characteristics ( like LS4 and LS4-a ) during take-off, landing and circling flight and its great manoeuvrability. Lower insect collection on leading edge of wing, meticulous attention to detail and high seating comfort for pilots of all sizes, add up to maximum performance for extended flights.
The LS4-b also provides easy ground handling due to low weight, simple rigging and automatic control system connections. This sailplane has proven to be docile enough for the cross-country beginner, and has enough performance to keep the experienced pilot happy on a long final glide.
. The wings are fabricated of
Fibreglass-sandwich-construction, as are the ailerons and horizontal
stabilizer. The sailplanes are still being constructed with the use
of gel-coat as an exterior coating.
