I would just leave a YT comment, but I don't want to make you have to double post or edit your own post for a new update. Always hated when that happened... if possible, you should straighten out your launch track. Slow down the video to 0.25 speed and the train does a little s-bend thingy. I don't think this is much of an issue since I'm sure you will have enough speed anyway, but I thought this would be good to point out.
Edit: And so page 2 begins...
