I have some on the way. I plan to put them on my profile foam F-22 with the little FC 28-05 2840kv motor with a 1000mAh 3S battery. That is the largest and fastest pitch this motor should take.
Here is what the plane looks like with a 6x3 prop. Dopler calculations have it at 63mph with a prop speed of 90mph. With this prop, the prop speed should be 105mph. If it is proportional to the 63 and 90, I should get around 73mph. Will give a report when I put the prop on and fly it.
