Ok.. Houston we had a take off. I'm suspecting the Master I loaded was 1.5.2 beta and probably had the changes made.
Loaded the mission, armed it...and moved sw to Takeoff... throttle was slow at first, but when I attempted to throw the plane it revved up.. So I know it will work now. I didn't actually executed the throw because I'm in town.
I have the logs, but I can't or don't have the option to upload them here.
