I also love the viggen, used seing them in the sky during my childhood and also during my military service in the Swedish airforce.
I got a friend of mine that’s a civilian pilot (and a DCS pilot), and of his colleagues is a former AJS37 pilot. This pilot has recently got into DCS and the Viggen module. When I get the chance I’ll ask him about his opinion about the flight model.
We plan fly together in GAW, of course in the AJS37????
