Don't do tricks with a misadjusted handle. You can watch a plane fly, watch the pilot, and see that the handle is misadjusted. Sometimes they don't fix it, even when you point it out to them.
How do you know your handle is misadjusted? If you can't get it to fly level at the correct height, either upright or inverted, that's a big tipoff. Work on it.
