Hi guys, Im working on building my FT Flyer and have gotten to the electronics. I made my own firewall which was a huge hassle but a good learning experience, mounted the emax 2213 motor straight to the firewall (Is that what I was supposed to do?) , and am now at mounting the propeller. I have two different kinds that come with the power pack b, the emax one slides right down where the other prop needs to be screwed on to get onto the motor. From what I read I don’t seem to need one of the little black spacers with the emax prop, so it should just be the propeller and the red screw cap right? Here is a picture of what I have on here does it look right for this motor? Will not including a spacer have any negative impacts? Thank you!
