Default RE: Pattern IMAC F3A questions

One more thing, Gene. I'll use the Half Cuban Eight as an example: The pull to 45 degrees is done sharply and cleanly, AND must be 45 degrees. You would be surprised at the comments from the judges "That was not exactly 45 degrees" and off come the points. Don't ask me how they know.. they just do.

Then comes the equal amounts of air before and after the roll to inverted. Keep the maneuver big. Big impresses them because it requires control and discipline.

This is why I've stressed on trim adjustments in some of my posts. Setting the airplane up properly with the right CG and thrust angle comes into play when it comes to the subtleness of some of these maneuvers. Slight differences can cause big differences in the flight attitude. When you roll to inverted, for instance, how much down do you need to keep it inverted and straight? If a lot is needed, then perhaps your CG is wrong, or you had to much up in the trim for straight and level flight. So a combination of CG and elevator trim may need to be tweeked to get it so very little opposite elevator is needed to hold a straight and level inverted attitude.
