Which 8" props w/ **6mm** holes for Suppo 2810 motors?

I just bought a whole bunch of gemfan 8" props for my suppo 2810 motors, only to find out that the shafts on the stock prop adapters are 6mm and the prop holes are 5mm and no way am i going to spend the next 15 years reaming out all the props i've got. i searched for 4mm - 5mm prop adapters and couldn't find them, either. so: who makes an 8" prop with a 6mm or or larger hole? i'm hoping for a quality prop but not a graupner-priced quality prop. something along the lines of the gemfan carbon/nylon mixes at 4 / $6 or $8 would be swell. Thanks!

apc have the right size hole if theres an 8" prop in left and right.... reaming props is pretty easy assuming there is enough meat around the hub to support it. buy a prop reamer if you do it.

thanks. but what a freaking ordeal. right now, instead of going the reamer route, i'm trying to find a 4mm (motor shaft) - 5mm (prop shaft) prop adapter, since the gemfans have a 5mm hole. why don't sellers put the prop-hole size of their props in their listings? you'd think that would be fairly important to know. jesus h.

BPH - Cheetah Prop Adapter Shaft: 4mm, Prop: 5mm (Shaft Diameter: 3.2mm, Prop-Hole Diameter: 4mm)
Prop Adapter for 4mm shaft - with set screw

Okay, for future reference, I found these two 4mm-5mm prop adapters. At least I think I have. The description of the first one seems different from the title of the item. First one is collet-type, the second is set-screw. Is one preferred over the other? Finally, the first one doesn't mention shank length, while the second specifies 26mm. Think 26 is about right for the Suppos in question?

update: went ahead and ordered the set-screw adapters. hope they do the trick!

you want the set screw type. make sure to grind flats on the motor shafts so if it does come loose, it won't leave immediately and let you time to catch it being loose.

they look right
