Wolfgang Mrotzek always had a faible for exotic airplanes. He initially designed the prototype for his F-35 Lightning II for a 90mm EDF, but changed to a Lambert Kolibri instead. Here are some impressions:
For my 50th birthday, my Indoor-team surprised me with a very special present. First they gave me a "3D puzzle" of the Xtreme3000 (the latest design of Martin Müller), and just when I said I would hardly ever fly such a unique model, Martin came flying into the room with the RTF version and told me those where just spare parts.
Now I have my very own model, signed by my Indoor-team, weighing 142g with AXI 2203/46 and Vortex 2/350mAh.
