The Bingo kit is ut of production.

Beautiful airplanes and great performers, but you are stuck with scratch building.
BTW:
RTF = ready to fly (almost never really true... usually takes 2 to 5 hrs of work)
ARF = Almost ready to fly
ARC = structure built... cover it. (close to ARF)
Kit = the box of wood and plans. Get the glue and get to work.
Scratch = you pick out the wood pieces from a list on the plans.
You can separate Scratch into 2 catagories.... Scratch built from (source) plans, or Scratch bult from his own design.
