Yep, Red Rover is correct, Dave Brown does indeed sell a 10x1mm adapter. I was looking at the Tower Hobbies site - seems that Tower just does not carry this part.

You definitely have to deal with the slot issue. Either you have to order a spinner with the right size slots or you may have to enlarge the openings yourself. Not sure what Dave Brown has in the way of slot options (seems pretty logical that Dave Brown could set you up with the proper slots). Tru-Turn has several different slot options - including standard slots, large "120" slots for APC props, "Big Bird" slots, and Menz slots for Menz props.

I want to run a Zinger 22x6 on my Moki 2.10. What is the proper slot option for this prop? ... I have no idea . I think I will forgo the spinner and go with a spinner nut or prop hub.
