Hi there, I do not think so. the entire X-plane with everything costs $ 60 for the skymax and realwetter conector i also paid $ 60 plus now another $ 20. and that for such a small detail. I don't think that's proportionate at all. a tiny plugin for the complete X-Plane.
I think it's a shame that you have to pay again for an update from 4 to 5, the discount is limited to 60 days. if you see the prices in relation to X-plane it is overpriced anyway. So we are really ripped off again. Eat or die
