SITL - Gazebo Tailsitter

Hi all,

I’m having some trouble running the SITL tailsitter code. Everything seems to work until I try to transition from multi-copter to fixed-wing. The tailsitter basically spins out of control as shown in the below video as it encounters a turn. Any suggestions would be great.

I’m running nearly the latest version on the master branch. (As of right now, SITL for the latest commit on the master branch appears to be broken.)
