Another juggler on RCU apart from me!blimey.
Hovering is easy.....................compared to pissing in the corner of a round room!
I found that if there is a cross wind blowing, it can get around the wing if your hovering, and push the wing round quickly, inspite of any aileron input to counterract. This made me really scared that it would happen low down, and that i would lose it, but now i just go with it and do a t/r back to a hover.
