I think you have described the Angel perfect Jack

I am so happy we can buy decent ARF pattern-trainers. Most of the stuff "out there" is 3D-stuff [:'(]
Btw; I liked this Sebart-gadget too much I think. Yesterday I bought a Katana 30S from Sebart. Just to have a plane to do hovering and playing with to avoid stretching the limits with the Angel. The Katana will be a cheapie, using stuff from UH.
