The hole is drilled way off center for one of the directions (r-turning). The other is fine. Its not a matter of balance- its the center- its very, very visibly off center- not a matter of bad balance. Some folks are going for a way to build a new hub. My other smaller ones- 7, 6 and 5 are all fine. It was true for the orange and black- as these are recent restocks its fair to say these are stocked defective with full knowledge from our beloved... hk.

I bought it knowing the problem with centering of one kind of prop. It is easy to eliminate this.
I use 5mm shaft so I describe it for this diameter.
Hole is 0,55mm out of center. Let take ring not for 5mm shaft but with hole diameter 3,5mm. Take 3mm drill and enlarge hole to the one direction. When it is 4mm (can be little bit more) it is OK. Let use drill 4mm and make the hole circle. And finally take 5mm drill to make hole for 5mm shaft. Now you have excentric ring.
Put ring to the shaft, put propeler to the shaft and now turn prop on the ring till be centered. Fix prop to the shaft and try start engine. When it is vibrating try to turn prop a little bit on the ring and try again. Let continue till you will be satisfied.
May be first try will not be succes, let try again .... with hole at the ring more excentric. But I believe finally you will do it :)
It is easy than fill and making hole again. You can use the ring after damage prop again.
It is unusable without handmade repair but I think it is OK for this money :)

Standard rotation prop was fine but the hole in the centre of the R-rotation prop is out of centre, it is the same across all colours so it is definately a problem with the mold they are using, perhaps it will be rectified in the future?
