Dornier DO-17z "Flying Pencil"   1990?
This DO-17z  called the "flying pencil" has a wingspan of 120",  powered by g-23's.  Scratch built retracts.   Actually was one  lousy design on my part.  The vertical stabs were scale but too small.  Attempted  landings in one direction normally resulted a landing at least 90 degrees from that direction.  At flying speed it handled ok but as soon as you slowed down it became a handful.  Sold it to a doctor in Waukesha, WI who has it hanging in his hanger.
