Hey, just curious. You guys have any problems converting to a 2 blade prop. I did, couldn't get a plastic spinner to fit properly. Back plate on spinner kept on warping when i would tighten propnut. Gave up and put one of those small metal cones on in front of the prop. Kind of forget ,think i had to add a washer too. Use the motor all the time but have been lucky not to break a prop in ages. Crashed my alpha too many times. The evolution trainer motor ,11/7 prop pulls my slowppoke great.
