Here are some pictures of the installation of our 3W24 in the new Cermark Pitts S2. This bird weighs without gas at 12 lbs. It turns a 18 x 10 Bolly. Has awesome power. Handles very lite in the air.

Very simple to modify the Pitts to accommodate the 3W24. The 3W24 also has a reed valve. Very smooth and has tremendous torque!
