Nice run! The track cruising is definitely cool looking makes me want to find some abandoned tracks around here to go cruise too. Think if you want to smooth out the video best bet is messing with rates so middle stick is less sensitive (I forget if I used RC rate or super rate but basically tried to make the curves look flat and helps so small adjustments aren't as obvious/twitchy looking). Some of it is just going with whatever direction you picked too or planning out a path and trying it a few times to figure out where you are over-adjusting direction.
