Tim That is a truly unique and cool project! I am aware of those models as shown on vogelsang aeroscale. OK about the engine. Mine is on a 91 inch 20.2 pound corsair with a 22x10 three blade prop as previously discussed on the thread. The power is excellent and I usually take off at 3/4 throttle and it will take off scale at half. The 24x10 will have more thrust and the engine is now 10% greater displacement. So there is information to ponder. -Tom
