"Keep Your Dragon Flapping" script has been updated by me. I created this script because I would go to tour a sim and see a dragon flying in the skies and it's wings would have quit flapping, so it's just sliding across the sky. Putting this script in with your script that animates the dragon will keep it flapping forever and you never have to reset it. This also works for flying cars, flying spaceships, birds, etc.
