RE: Ultrafly Ultimate
That park 400 should be good for any 3d plane that weighs between maybe 15 - 19ish oz. I have a park 370 in a plane that weighs by my best guess 15 - 17 oz, it works fine. I find that eflite seems to underate their outrunners... That 480 ought to have more than enough power though, I hope you enjoy.
