Hi guys,
One thing you need to think about is that once the plane get to about the 1 oclock position you need to be pushing it to the outside of the circle, and then let gravity do its thing from about 11 to 9. Then really pull the the center of the loop from 9 to 6.
Which all really comes down to burn a lot of fuel.

one more question are you trying to do this in one roll or a half dozen or so.

Mike,
