Yes per the Static Thrust Calc software incorrectly used to reach "unloaded" numbers per post #824:

"If unloaded" numbers come from plugging in props keeping close to the hp base line manufacturers spec data of .065hp at 31K"

APC power charts per post #835 provided good static data as previously mentioned.

So I now have a static base line from the brief preliminary tests using the APC power charts and Static Thrust Calc.
Vertigo .07
APC 5x3 / static 25,227 / .24hp / 179w / 18oz / 72 mph
APC 4.75x4 / static 24,739 / .225 / 168w / 14.5oz / 94.6 mph
