Does what it says on the tin, well balanced and no slippage. at this price I was expecting a lot less. I did have a small amount of burr in the thread but it came away with no problems.muy buena calidad del material
excelente productoGood for the mini swift upgrade motorwell balanced... I'm using them primarily for planes, I don;t know how good will they be for multirotors.I bought 8 in two orders... in the last order 2 of them were bad...the shaft size was wrong and could not screw the cap to close on the propeller.I use this for my axn stock prop.because i did not use the o-ring,it fits the motor shaft and holds the prop.perfectly..so far i have 10 flights with no problem occurs.i use 5x5 propeller..thanks HK..for good quality and fast delivery..Great for quadcopters motor shaft size.
exelente calidad Muchas gracias hobby king !good prop adapter. it is better if price loweri prefer these to the Collete type as they seem to have less
tendency of run out but the grub screws are garbage and i use others bought from local supply
