It does not stall out due to damage! Of course, slamming the brakes all the way will cut the engine, but the engine will not eventually break down. The engines will still cut out for those half-seconds periodically though. Pretty cool, but could you imagine if this thing had weapons on it? People could stay in the air constantly unless they crashed or got shot down by another one. That would be the new Tank era, which would not be good.
Anyway, if you want to fly in the air without worrying about damage to your plane, the Besra is the way to go (unless you meet a Lazer)!
