sorry Bill, but you,most likely, wouldnt like the pits with the homie 25cc. The home 30cc would be much better or a 33cc-38cc saw engine conversion from a pullan chainsaw would be ideal. It would fly with the homie 25cc, dont read this the wrong way, but it wouldnt have much in the way of vertical power. Maybe one or two vertical rolls before it fell out, remember the pitts rolls very fast so thats not that far to go. I guess it would fly like one of the early pitts, you would have to plan a maneuver and conserve you energy and use airspeed to your advantage. So it , in the end, depends on how wild or mild of a plane your wanting it to be. The advertised weight is 9-10.5lbs, I always add 2lbs to that for a gas with mag motor. Might need a bit o lead in the tail too. So the pitts might realistically weigh in at 13lbs or a bit more depends on how much the manufacture fudged the weight. Piper
