so in the end, a three blade prop spinning at the same RPM as a two blade prop indeed has more drag(theres one extra blade catching air) and therefore requires more power to do so. Correct? But more drag means more pull for the plane to use in thrust right? So doesnt that, in itself,(this is me trying to comprehend, so be patient)explain the simple rule of supply and demand...in the sense that in order to have more thrust, you obviously need more power or higher revs out of your engine anyway?...meh...if i make any sense cool...if not, kill me now
