@Ben_E: Thanks. I consider that downright fraud. I did not expect to find directly contradictory statements like the Watt/Ampere/Volt-Thing so I did not check when I bought it.
@Concordefan: Thanks, I used Google SketchUp but can not recommend it. You can't draw splines and a lot of stuff you would expect to be there like automatic measuring is missing. (Maybe it's me) Next time I will use a real CAD-program. Although as long as you just want to build Foamys without complex curved surfaces it's probably a good choice because it's very intuitive.
Please Notify me when you start your Gimily Glider. Are you going to build it with or without engines?
ps. ready for take off:
