You have sharp eyes to spot the Aurora in the Avatar. YEP, this was my favorite plane in the early 90s, and I still have it. I flew this and a Brushfire in competition.
The U-Can-Do 46 will never be a pattern plane and the Aurora will never be a 3D plane. At least not when I am flying it.
I know all about bad backs. The U-Can-Do is the plane for you. I have three. Two with an OS 91 4C pumper and one with a
OS 50 AX. I use the 91s for float flying as well as at the field. I don't have much time on the 2c engine yet. I might replace it with and OS 70 4c.
I find I can't enjoy electrics. I keep waiting for the battery to sag. If you don't have extra batteries, like a bushel of them, you are done in 8 minutes. At least with glow, thrust is the same from beginning to end and you can fly all day on a half gallon of fuel.
