As It was discussed here as well, that the 4 strokes can turn larger size props, I have one more question honestly speaking I wanna increase my knowledge that if in 4 stroke we use larger size prop, ofcourse as it can turn larger size props, what would be the effect on speed? speed of the airplane would increase by using a larger size prop on 4 stroke or using little smaller size prop using 2 stroke engine with higher rpm? Higher torque would give more speed or higher rpm would give more speed to the plane?


Pls clarify me
