These are two tracks. Tonight I succeded only once in taking off with undamaged tires, but I really don't know what I made different :). I also tried a couple of times without afterburner, but the take off run is much longer and tires blow off the same.
It looks like the tires blow off at around 320 kmh, but my plane takes off much over 400 kmh, which really seems too much, I must make something wrong. I also tested the Mig-29S without any problem.
By the way, isn't it possible to see the airfield number in the Su-27 and Mig-29 when cycling them in navigation RTB mode? Su27TO.trk Su27TOa.trk
