Hi Cubanace,
The development of your T-50 is looking really good, it's coming along just fine, the cockpit is taking shape so well done. Nothing wrong with using the SU27 as a base.
Been using the current T-50 with SU27 cockpit for a while now, good to fly but can't wait for yours. Accurate texturing of each aircraft and pilot would be good.
More development videos please, if you need a tester I will volunteer
