Who did invent / introduce the spring-loaded VP system to indoor flying?
A friend asked this during the Finnish Champs yesterday, and I had to
confess that I did not know. I recall seeing pictures of Joachim
Löffler's F1B (wakefield) hub from the 1960's, using that mechanism
where torque on one bar and prop on another produce the blade twist. The
first picture of an indoor adaptation I have seen is the Richmond (?)
drawing in INAV in the 80´s I think, but that seems to be a
well-established concept already, so the initial use has been before that?
