....yep....higher RPM and more pitch gets you the speed.
you can get to the point the prop is too small for the airframe and you start to loose allot of speed because you're prop washing the airframe and not pulling through the air. my Patriot 40 does great with a 8.75 and 9 inch props but looses allot of speed when dropped to an 8" prop and takes a good 50' more runway to get off.
