PS: I believe that with this motor, the GWS 8x4 is better for WOT around 60 km/h and below, the APC one is better for WOT around 80 km/h and above, still the APC always leads to a more powerful setup.
Wow... thank you so much for sharing your results. It gives me some closure in knowing that I wasn't completely wrong but simply using a different prop.
Do you have the link to the GWS HD 8x4 prop that Dr.Kiwi was using by any chance?
