The Schneider Grunau Baby (named for the town where Schneider's factory was located - now Jeżów Sudecki in Poland) was a single-seat sailplane first built in Germany in 1931, with some 6,000 examples constructed in some 20 countries. It was relatively easy to build from plans, it flew well, and the aircraft was strong enough to handle mild aerobatics and the occasional hard landing. When the Baby first appeared, it was accepted wisdom that the pilot should feel as much unimpeded airflow as possible, the better to sense rising and falling currents of air, temperature changes and the like.

It was designed by Edmund Schneider as a smaller version of his ESG 31 of the previous year, incorporating a new elliptical wing design based on work done by Akaflieg Darmstadt. The intention was to create an aircraft suitable both for training and for cross-country soaring. Typical for its day, it was a high-wing braced monoplane with a fuselage of hexagonal cross-section and an open cockpit. The Baby was an instant success, and was enthusiastically promoted by gliding champion Wolf Hirth. An extensive redesign followed in 1932 following the fatal crash of an unrelated Schneider design, resulting in the Baby II. This version and the definitive Baby IIb that followed it were adopted as a standard sailplane trainer for the German Air Sports Association

IMPORTANT NOTE! Make sure you check the wing incidence, especially if you glue the tail down as it will not be changed.

Tail at 0 degrees, wings should be at 1.5 degrees

Centre of Gravity is at 106mm from the wing leading edge at root (3% static margin)

New for 2015:

The kit has been slightly modified following a few builder's comment.

The main modification is the wing profile. It is now a HQ 3.5/12! Better wind penetration for the slope flyers, but same, if not improved, performances for the flat field pilots :) The wing incidence has been modified too while I was at it :) (older kit owners, please remember to follow my recommendation to put a 2mm piece of wood under the tailplane LE!)

Fuselage is the same, but I have changed the way the elevator is build. Much easier, and the mistake made following Martin Simon's 3 view on the elevator has been corrected.

Mid 2014, the kits should also include the modifed "Fokker" rudder. 1 kit, choice of 2 gliders :) If you want your kit to be the Fokker Grunau before this date, please let me know. I will be more than happy to include a pre-production one in your box.
