Hi folks,
these are professor Alexander Lippisch designs which led to the (in)famous Me 163 Komet.
The DFS 194 by PM Model is more a toy than a kit, so it required quite some extra work.
The Me 163A from Special Hobby in its later reincarnation is still quite OK, and also includes the Scheuch-Schlepper tractor, which is pretty nice little add-on (some says it is actually Scheuch-Schlepper kit packed with an ugly airplane).
I'm sure I'm not the only boy in the town eagerly waiting for new Valiant Wings book on (not only) the Me 163 to complete the whole family.
Cheers,
Libor
