My elevator and aileron are setup at 35% right now and I am not having any trouble. I have my head setup to give me +11 to -11 in idleup. You really don't need much negative pitch for basic loops and rolls. I only get slightly below midstick on the top of my loops and rolls. Check out the [link=http://www.helifreak.com/showthread.php?t=12337]Flight Training Videos on Helifreak[/link]. Finless is flying basic loops and rolls and has video of his transmitter imbeded in the corner. Finless and the video do a good job of showing how to do these moves.
