Did you get your pitch set yet?

Every motor is a little different, and it depends on where you decide to measure your blade angles along the length of the blade. We typically recommend you measure about 3 to 4 inches in from the end of the blade - in a place you can set your digital angle finder. I would recommend the same blade angles for all blades, and roughly 8 to 10 deg to start. Your target is a full throttle setting of around 2700 to 2900 RPM. Each degree of change in pitch will make about 100 to 200 RPM of change in your full throttle RPM.

I know some like to set a delta between the two blades on each side, and I think it's usually about 2 degrees difference.

Let me know if I can help with anything else.
