I have the Fliton Edge 540 with a saito 100 on it, and talk about a blast to fly. (over powered= just right) I think the specs are close on these 2 planes so the magnum 91 would be a good option, and would fly it fine. I have several of the magnum engines, and get great service from them. I have the 91 magnum on my UCD 60 and its a blast to fly. Hobby People has the magnum 91 on sale right now I think $139, can't beat that.
