Recently I've done some comparisons of the 5 Sailplanes above for my own personal use and I share this now with others to save them the work of collecting it themselves. Of the 5, all but the SGS 1-34 can be bought new. There is a lot to consider in buying a sailplane. The most comforting part is that they don't seem to depreciate unless they are involved in an accident. The following table is a summary of the data I have collected, followed by some personal discussion.
Some test data exists that dispute some advertised performance claims.
IF you are about to buy one of these new sailplanes please collect the latest literature from the rep and rely on their most current information, offerings, and pricing rather than relying exclusively on the information presented here. Can leave tied out. Favorite in many clubs. Easy to repair and maintain. Schweizer still supplies parts as needed.
