I'm learning when it comes to 3d, but just managed to get my flip to hover today, I entered it from a harrier and it stayed there for about 30secs and then it fell to the left. I tried it again and couldn't get back into it and it kept falling to the left, eveytime it started to hover it fell to the left no matter how much right I put in. Any help with what I'm doing wrong would be really great?
