Cheers fubar57. I, for one, will take all the help I can get. It was devastating for me as a young would-be fighter pilot in 1961 to find out I was red-green colour blind. They handed me a Bren gun (loved it), a Heller antitank rocket launcher and, finally, an FN C1 (amazing weapon). Now, I have to do my flying by modelling and drawing. Not the same. Doug.
