Nope, it's a custom project from Heiko Höft and Wolfgang Weber. They each built one....they are absolutely scale down to the airfoil (razor-sharp and ultrathin!) and the canopy-opening mechanism. They do have molds as far as i know....not sure if they're willing to spare some parts.

SJN has pointed out most of the scale flaws (apart from the anhedral), but i'm sure its a nice little flyer :-). The Avonds is also a piece of beauty....
