RE: Who really invented Digital Proportional?
I think I seen this site once before ...smaller though. Loved the ability to zoom in real close. I've had or flown, Orbit,WE Expert,Kraft open gimbal, Heathkit, Ace, Cox , Airtronics, Hitech, Blue Max, some old tone gear (can't rem name) a Venus reciever on 27, Futaba, Tower, and maybe a few others I trained owners on.
This is quite a site and collection with well laid out searches on every mfg and model..
Great find!!
