I built the Tiny Dancer over the Spring/Summer 2009 period. I started the design before the AR6400 brick and external servo first became available in the PZ Sukhoi. With this plane I wanted to try a skeletonized aiframe skinned in very thin foam. I used Durobatics 025 foam for the skin. Essentially I lowered the airframe weight down to about what it would be if I had milled pockets in the Depron, about 30% lighter. Wing span was 18in, and final weight was 37g. Propulsion was Mighty Midget BL 1-cell. The thread is here
This plane has been retired. It hit too many walls while I was learning to turn with my left thumb. I'll probably do a second version with clear mylar covering for my son in the next year or so. I offered that we could build him an Air Bender or Tiny Dancer and he chose this one.
