Engine on WM Dago Red .46
I sold my DagoRed a few months back. I installed an ASP.75 2-stroke inverted. Plane ran like a champ, and was VERY fast. I'm currently getting back to re-finishing a WM Mustang that was given to me in shambles(not to terrible, enough to be unflyable though). I'm putting a .61FX with tuned pipe. This after the rest of the air-frame has been on a diet, and had some strength management. done to it. Should be a true speed freak.
You would do real nice to go with at least a .61 in the Dago though. They weigh about a pound more then the balsa counter part, due to fiberglass structure.
