Nope that wont fit. I think it is about 2mm. By a drill bit and drill it out :) Simple :)

That cant be 2mm on propellers this size, would gess either 3mm or 4mm.

 robert199 9 points

Ok, just for you, I got the calipers out and I'm telling you they are less than 2.5 mm. Honest! I was surprised too... I had to drill them out... Suppose that is what you get for cheap props.

 Henry. 52 points

Tnx for the measurement! Under 2.5 mm thats insane! A motor with that sized axle would be far from able to rotate these props, but i will by and try drilling the hole and hope it would still hold to gether at say 7krpm.

as if you would drill out a prop.....you will never get the thing to spin true no matter how much care you take. Don't buy a prop if you need to increase the shaft size, just get another prop.

I did drilled 4 out and they all run perfectly true, and even better then 2 others that i haven´*t drilled out yet so i dont agree one bit. You just have to knowing what you are doing and just not "drill" and hope for the best because then they will be far from true.

what i can see from the picture, looks like same with GWS 10 x 4.7 , the hole size is 3mm. i am gonna try.

 robert199 9 points

Its hell 2.x mm only! I got my quad ready to fix on the prop and stupid to see such a long prop with a pea brain hole size! Same, am using NX4008 that has a prop saver around 4.8 mm. And I drill through too only to realise the prop saver is not long enough.. damn..

Why would they?
You should balance them your self.
It's not too hard and you will know is done properly.

 Boris 11 points

This prop is lightweight. So it can be balansed by one hands move. Use cutter or scotch www.link
