I ordered the 11 x 4.5 MR/MRP props from APC, and they arrived without the little adapter rings (apparently you have to purchase those separately... Doh!). 

I tried to fit them to my stock 3dr quad kit (with the 880kV motors) but the internal diameter for the propellor shaft is much larger than the Slo Flyer series. So I cant use those adapter rings. Also the prop is much thicker, so I cannot fit the washer and nut on top. Just the nut, which will screw down inside the prop and keep it centred, but I do not like the idea of flying without a washer between nut and prop.

So...

where do i find an adapter for the 880kV motor that will take the APC MR series props!!

I can't find anything on Hobbyking...
