Numbers from yesterday, all on the same lipo and not recharged between.
APC 12x6, 10650rpm, 46A, 761W
Vox 13x5, 10110rpm, 42A, 646W
Vox 13x6.5, 9300rpm, 51A, 796W
APC 13x6.5, 9390rpm, 60A, 950W

Today, fresh lipo each time but not same lipo (maybe in IR issue leading to strange numbers).

APC 12x6, 10200rpm, 44A, 686W
APC 13x4, 9930rpm, 53A, 841W
Vox 13x5, 9930rpm, 41A, 615W
Vox 13x6.5, 9300rpm, 55A, 883W
APC 13x6.5, 8850rpm, 56A, 895W

Numbers still feel a bit screwy to me, but you can clearly see that the vox spins at higher rpm than the same size apc prop where you would expect. One would assume this means more thrust on the vox over the apc, but I have no way of measuring thrust apart from flying.
