Hello there! Reporting possible bug here. The rear wheels on the Su-27 seem to enjoy popping with some ridiculous regularity. In my experience, any time whatsoever that a constant wheel brake pressure is applied for over a few seconds, the wheels will pop, even when in perfectly straight movement. This is most prominent in landing, when I can't actually use wheel brake to stop, but have to use the drag chute alone.
You can see this poppage in action here, as well as in the attached track (same track as video). Happens in the current 1.2.14 open beta, no clue if this is in other versions.
