DF Picco 45 with pipe.
I forgot to mention that now I'm flying a 40 Shirke with a Tower Hobbies .40 with a muffled tuned pipe. The plane is good for about 100 mph, and unlimited vertical, the guys at the field think it's fast, boy are they going to be surprised when I bring out "Turbine Waiver". I also bought a OPS .61 with pipe if the Picco 45 isn't fast enough.
