I really need help with props

[CMonteiro]

Being a complete beginner with my x650, I feel that I would need to change my original propellers by others with a more gentle slope or an inferior diameter.
So I have been looking around for other alternatives but I get completely lost because thare are not many choices on pairs clockwise and counterclockwise.
But what makes things even worse is that when I find them, I never know if they fit my motor shafts, threaded at M4.
And I don't know if there are any adapters or at least I can't recognise them as the right ones.
So please help me.
What I found as alternative for the original 12"" and I guess 4.5" slope.

- XAircraft 450 » 10x4.5 Propeller Set (being the same brand, these must fit)

- 10X4.5 SF Propeller Green (pair) from this link (but I don't know how they thread) http://www.quadcopters.co.uk/?PageID=ShowItem&Item=10GRCCW&Desc=10X4.5

- Propeller pair EPP1045 / 5mm CF (could I use an adapter?) : link : https://www.mikrocontroller.com/ind...id=562&zenid=77c84e2eafd41029d08e12ffd243aeb8

- 10 in. Props - Gaui from this link:

I am arriving to the conclusion that xaircraft motors with m4 shaft threads don't allow any changes. Should I have to replace motors to have more possibilities of choyce?
Please give me a hint.
Thanks a lot

HI , If you have the original X650 then the props are 12x6 and yes they are threaded centres.
The 10x4.5 for the xaircraft x450 do not have a threaded shaft as the original x450 used smaller motors, and the new Xaircraft range of quads all use 10x4.5 props but the centre is oblong now to fit there motors.
However a few people have used the Xoar props and the graupner 11x5 with good results , I dont know for sure how they mounted them but i know they have used them .

Thanks a lot.
Now I know that somehow it is possible to use other props.
And now I hesitate between two possibilities. May be you could give me your opinion of whitch would be the best solution for a more smooth and easy flight:
1 - Graupner E-Prop 11x5 propeller (found them at Aligator.com)
With this one I get a lower diameter but a higher slope.
2 - APC SF 12x3,8 (found them at himodel.es)
With this one I get the same diameter but a lower slope.
Could you comment?
Thanks a lot

By the way, if you have something adequat at quadcopters.co.uk, I'll be glad to consider the purchase.
And about the fitting, well, if necessary I may order an adapter made by a professional after receiving the props.
Thanks again

I am ordering Avroto motors that have 4mm shafts. Anyone know where to get a prop adapter that is 8mm to 4mm ?

mcmaster.com makes a nylon spacer in different outside diameters, different inside diameters, and different thicknesses. they're pretty accurate and inexpensive.
part #93657A143 or something similar.
