Don't laugh ! Don't know if it's me, lack of experience or if it's just normal and I expect too much. If trying to fly say a 10m diameter circle it's anything but a perfect circle. More like I've had a few to drink beforehand :mrgreen: I'm only using right stick, no left. If I introduce some yaw that helps a lot. So how close can you expect to get to a perfect circle ? Can one do a say 3 or 4m diameter circle or is that too tight? When doing circles I notice a bit of yaw creeping in too, maybe 10-15 degrees. Is that normal too? Apart from that, straight line flying, boxes, ascent,descent all fine.
