HI Xantos!
There is an english manual,send Thomas an e-mail.... Guess what:The only part missing is mounting the ventral fins

. Damn, I knew I missed something...
We glued two short carbon pins in the fins, drilled the matching holes to the fuselage. They are parallel to each other. Just compare to pics of the fullsize.
We glued them after painting with contact-glue (UHU foam-glue). YOu can get them off easy, but they won't come of during flight.
BR,
David
