RE: Tiporare in SPA?
Dick did not built 150 prorotypes. He built airplanes that were sold. Frame ups, he didnt finish or fly them. From the time I met Dick and Guy in the fall of '77 till the time they moved to Utah in '79 or '80 I saw them with/fly 3 models. A wood Curare. I think TonyF later bought that model from Dick. A wood Tioprare, and a glass Tiporare from the WK kit. The latter was Guy's. I remember flying against that model.
Point being these were not prototypes. There was ONE prototype for the Tipo, then the production model.
Yes Tony is right too, Dick was an amazing builder and could pop out models at rate faster than anyone I have seen.
