AMS is the new LS4 models owner and Type certificate holder and care for these world popular and pilots likes gliders.

Spare parts and technical support are available at AMS.

Given the continued interest in the type, the LS4 has been putted back in production by the AMS-Flight. AMS manufacturing of new LS4-b sailplanes started in 2006. Two LS4-b’s were AMS delivered in 2007. LS4-b new manufactured sailplanes orders are possible at AMS. AMS starts the new LS4-b gliders production in series every time after receives minimum of eight options which became actual orders later on. This of the way and system enables to AMS to perform the smooth product line organization and production including the acceptable economical interest.

The idea to develop LS4-b successor with 18 meter wing is present at AMS.

The Rolladen-Schneider LS4 is a Standard Class single seat sailplane manufactured by Rolladen-Schneider Flugzeugbau GmbH between 1980 and 2003. The LS4, successor to the LS1 in the Standard Class, made its first flight in 1980. It is the third most produced non-military glider (after the Grunau Baby and the Blanik basic trainers). A total of 1,048 were built until Rolladen-Schneider entered receivership in 2003, AMS-Flight manufactured and delivered two more in 2007. LS4 long production run is comparable only to that of the Schempp-Hirth Discus.

The LS4 won the first two places in the Standard Class at the 1981 World Championships in Paderborn, West Germany, and the first six places (and twenty-one out of the first twenty-five) at the 1983 Worlds in Hobbs, New Mexico. It is still a favorite in handicapped competitions and as a club and recreational aircraft.

This type consolidated Rolladen-Schneider's reputation for well rounded sailplanes that are both easy to fly and top performers. It is docile enough for beginners and its performance is only slightly below the latest standard class sailplanes. We can conclude that LS4 is a real world standard class glider. The LS4 was succeeded by the LS7.

The design of the LS4 was influenced mainly by the experience Rolladen-Schneider had gained with the LS2 and LS3 flapped gliders. Wolf Lemke returned to a double-tapered wing plan-form, giving it a larger area comparatively to the LS1 and LS2, and enlarged all control surfaces: the ailerons were elongated and brought further inboard and the tail-plane span was increased.

The fuselage and vertical stabilizer were taken from the LS3 moulds. Other notable features of the design were the retractable landing gear, the centre of gravity tow release that retracts with landing gear, the heel-operated wheel brakes, the upper wing surface air brakes and the water ballast system with internal bags.

The structure is entirely glass reinforced plastic mostly with synthetic foam cores. The exterior coating, as with most composite gliders, is gel-coat, which protects the load bearing composite from humidity and UV-radiation, and is thick enough to allow wing profiling, which is done by hand during the finishing stages of manufacturing to achieve the smoothness required for extensive laminar flow.

• The LS4-a featured larger water ballast bags allowing for an additional 15 liters (3.95 US gallons) of water to be carried in each wing. The landing gear system is strengthened by the addition of one extra set of shock absorption bumpers in order to handle the increased gross weight with a full water ballast load.

• The LS4-b has a vertical height increased by 0.11 m (.38 ft) to 1.43 m (4.69 ft). The -b fuselage is 0.13 m (0.43 ft) shorter at 6.66 m (21.84 ft). The wing shells are made in carbon, control connections are automatic, the instrument panel tilts up with the canopy and it has an optional tail fin water ballast system.
