Prop size

[Supercubber95]

Here goes- What difference does it make in a planes flying ability when you put on different size propellers? Other than weight of course. What would happen if I was to put a 9" prop on a 16" wingspan plane? Thanks.

The torque would change dramatically. the bigger prop would spin slower, causing the plane to want to roll counter-clockwise,(that is, with guillow props, they all spin clockwise)

Very logical. Thanks.
