This is a very high quality, high performance slow-fly model. A Hand built Indoor ultra-lite weight competition flier, the Stubenfliege is the brainchild of Stephan Dolche from Germany. (A well known leader in lightweight carbon fiber construction) The Stubenfliege is an amazingly constructed plane, it is very light and very well put together. Comes with a custom hardwood storage / traveling case! Purchased this plane Braun Modell Technik many years ago (20+). I paid over $800 excluding getting it shipped, which is apparently others’ experience as well. Not many were made and it is no long available, and the custom box is especially rare.
