I've seen your video and its just amazing, Jason! You really know how to move the sticks

How do you do it to move your QHOR in a circle while hovering (from second 13th to 17th, +-)?
By the way, I've also made mine longer (95 cm fuse), tih 3.5" ailerons and 4-5" elevator, and a 40 fx. What do you think? Any ideas for a prop (10-4, 11-4, 11-3)?
