I Just installed my moki 2.10 onto my wm extra300. I put the spinner backplate on then an apc 20x10 prop then the supplied washer and nut. There is no threads left. How am I supposed to install a spinner adapter nut? Am I missing something here? I cant believe that Moki wouldnt make the shaft long enough to accomodate this setup as i'm sure it is quite common. Please advise.
