According to HH spec sheet on the Saito .72 the benchmark prop is an APC 13x8 @ 9800. Flyinlawenda's video with an APC 13x6 yielded 10700, less pitch but 900 rpms greater. Not bad and not a lot of disparity.

Further from HH, "In the 7 1/2-pound Super Stick, the .72 gives unlimited vertical performance." It is seeming possible that the Evo 10cc could reach the 7.25 lb thrust level and therefore the top of the 6.25-7.25 thrust range I guessed at a few days ago.
