Gubar: Thanks for the heads up. Appreciated.
Tweet: Cool. Good to have you on board. Be interesting to see how you get on.
Im just uploading another playblast to Vimeo, I've made 8 so far trying to get this right! In the last one I broke the connection of the paths U value so that I could hand key the speed the helicopter travels along it, the initial lift off the floor was just too quick. I think the speed now the helicopter travels along the path is better, although all the Hind Groups rotation keys are still there from the default speed so they now look out of place, have to re-key all of those. The Vimeo link above will get to the videos, but the latest 'more correct' playblast is still uploading right now. Should be good to go in 30-60 mins or so
