I've always heard that multi-bladed props give less thrust than 2-blade props. That has also been my findings as well with some models. I had a 3-blade prop on a .60-sized P-40 and a 4-blade prop on a .60-sized Spitfire. Both looked awesome on the ground and in still photos while in flight but they were definitely slower than their 2-bladed glow-powered counterparts (even though mine were electric and superior in every other way ) I kid... I kid... don't anyone get their knickers in a twist.

Performance went up significantly in both cases after switching to a 2-blade prop.

So is that to say that if WWII fighters such as the F-4U, P-51. etc., had 2-bladed props they would have been even faster? Assuming ground clearance for the prop wasn't an issue of course.
