Bruce, as I understand, the figures above are for a GWS EP5030, not a HD5030.
By the way, is there a difference between the two w.r.t. the thrust at a given
rpm?

Those props are one and the same....GWS only make one 5"x3" prop and its shape is essentially the same as larger GWS HD props (say, 6x3 GWS HD and 7x3.5 GWS HD [top row].... and 8x4, 9x5, 10x6 etc...some sellers call these DD just to confuse us)... there are small paddle bladed GWS props which are the only GWS props which I call DD (say, the 4x2.5 left end of second row down)... and their RS series props (like the 6x5 GWS RS in this picture) which are somewhat comparable to APC SF in blade shape.

Thanks, Dr. Kiwi, that's an useful piece of information which should, but it's not available easily from the manufacturer and the resellers.
