I managed to test this briefly last evening. Control assignments are simple. The engine needs to be treated nicely, no abrupt throttle movements. I also experienced what I think was a compressor stall and shutdown when doing a sudden nose pitch up. Flight model feels great and reminded me of the great Milviz model. The cockpit is too grimey for my liking but spectacular nontheless.
I even managed to bag a Mig-19 in a dogfight using an AIM-9B. You know the ones that are rear aspect only and not too maneuverable. Overall, I like it and plan to have good fun with it in DCS.
