References/Notes:

These ARE F4U-4 stock propeller blades, intended for taxi runs but NEVER as flying propellers.

"Online resources state clearly issues with four bladed props developed explicitly for the XF5U caused unmanageable and life threatening vibrations"

This is wrong. The vibrations were induced by the gearboxes and driveshafts, NOT the propellers.

"...reduced/resolved with installation of F4U-1 three bladed props as shown in my last photo post."

Wrong again. The photo you are talking about is the mock-up "dog and pony show" piece, not the final XF5U-1. There was NEVER any plan to employ 3 blades props. The cuffed wide chord blades shown in my second picture are THE PLAN. 

MAC has plans and vellum which have never been digitized. Traditionally the majority of
model plans have been produced through a process of Xerography, an optical process
resulting in percentages of distortion and enlarged line widths outward from the centers
of each plan sheet. While less expensive, it tends to distort plans incrementally.

You have seen me refer to this as copies of copies. You would be amazed when learning
of designers using Xerographic duplication of plans they sell, copying copies of copies.

MAC sells only "plotter printed" plans...with narrow line-widths to assure proper interlock
fit of laser cut parts. 

Digitizing requires auditing each plan, inch by inch, to assure there are no faint, partial,
and, broken lines within each MAC plan cut path. Unless this is performed plans can not
be laser or CNC mill cut accurately. This is why MAC is initially selling laser cut kits of all
original size Jack Lynn Bale plans.
