RE: WHAT APC PROP IS BEST FOR PKZ F4U CORSAIR
I ran a 10x6 and 10x7 with no problems. I also ran a 11x6, in which it pulled the motor "slightly apart" from the spinning part and the shaft. I had to remove the motor and press it back together.
I did a current and wattage check on each prop, and believe it or not, the original prop seems to work the best. There was not a noticeable difference running the 10x6 or 11x6 in terms of speed (both APC and masterscrew). If you decide to change the prop, you need to ream out the center for the original prop has a slightly larger diameter.
