If it doesn't fit, drill it out.

 Alexander9800 19 points

yes you can the standard hole in the propeller is actually 6 mm :)

 Alexander9800 19 points

Depens on what motor you are using. I use these and 10x3.8. But I do like the 11 better

 Nicola 8 points

the propeller is fine but you have an ESC from 35 A

 CHRIS SV AZ 193 points

These are standard props, they are not counter rotating

Hello, it will be good if you use it in big size of quadcopter .. idont have much knowledge on the quad... but i see someone who use it in a normal-big size... Sorry for this disturb :) Best Regards

No, you need an 12x9 prop or one more similar to a 12x9.

it would work but with less efficiency!

 Natescraigslist 3 points

if you lose 1 inch in diamiter it will reduce your power. if you half the pitch again this wll reduce your power. and likely if the cub is equiped with a NON Slofly prop then it has a higher rpm spectrum that the slow fly prop can be efficient while using, the 12x9 prop spins much faster and grabs more air at a higher rpm while the slowfly prop is meant to spin about 1/3 to 1/2 the speed.

Hello.. yes difinitly.. and its not have a more ductility(Flexbility).. i am using it almost .. another thing is these propellers not suitable for any jet plane..Best Regards

If you use it for multirotors, i do not recommend these. But GWS 11x4.7 instead of this one. But if you use it for aircraft it works really good.

i tried to scratch and rub on the outside to see if wood is hidden beneath - with no sucess. simple, well made cheap plastic

i use it on my 3d flyer and its great

 Hussain Joharji 205 points

Hello.. yes it will fits...but what i want to tell you know is that this propeller comes with a adjustable washers for different diameters.. i hope this help.. Best Regards

 ubayrakci 34 points

You can adjust with washers easily. But some shafts are too big to fit. At this situation, you can drill it via drilling machine or razor blade knife.

 Lamborgotti 42 points

i have these for a motor with 6mm shaft, they come with plenty different adapters, also a 6mm is includet, but its really tight. apply one small drop of oil, WD40 or similar on shaft and it fits perfectly!

No, Turning it over doesn't reverse the airflow direction. You need a reverse pitch prop made to turn in the opposite direction as a standard prop. Good luck with the search. Cheers!

 Awni 164 points

No you can not turn it around, you will need to find a CCW Prop

 Awni 164 points

I also searched HK for those adapters alone, no luck, unfortunately I ended up buying the props this way I will have spare props and adapters.

 Henry. 52 points

Yes i hade planned on doing so my self as well but there was another prop under 1$ that had adapters as well, but dont sure they would fit this but it was so cheap so it doesnt matter if they wouldnt.

 rcfever 24 points

I could not find them either sometime's parts like that are best bought at your local store that way you know it is right

 Henry. 52 points

True, but i dont have a RC store in my city. I got a lathe though so i think im going to make me the one i need and by that way i would definitly get the right one.

 rcfever 24 points

That should work

 Lamborgotti 42 points

Simply use shrink tube on your motor shaft, old trick *-)

 KaosKane 1429 points

A bit big but for climbing power tourque u cant go wrong...... for speed u need rpm so go for the 9 inch version of the same props just check for DD dirct drive not RD reduction drive (gearbox)

 cyclone_ 41 points

It should work ok, but the best way to tell is simply to try it out. The recommended prop size for the 2217 is 10x6, so switching to an 11.4.7 will theoretically give you great thrust (larger diameter) but slower speed (smaller pitch).

 Vasiliy 2 points

Thanks! You answers very informative! And I need thrust, not speed.

can't find any Counter Rotating for my quad, can I just turn this one upside down?
