That's right flyboone, the "hovering in a circle thing"
In your video it begins after the 12th second or so and yes, its like hovering but while making a circle around a external axis.
Is there any chance of pinwheeling a PQHOR? I have no idea why they should KEdge so badly. I'll put some covers on the tips on the wing, lets see if that makes something (at least its improves esthetics)
