I have DYS BX2212 980Kv motors which have special slot for propeller.i need 9" props.where can i find them ?
for reference i am attaching pic of the motor shaft .the second image is of 1045 props bought from quadkopters which firt the motor perfectly

hi,
purchase some genuine APC 10x3.8 props and bore them to the correct 8.9mm size so they'd fit on the Bumblebee motors. I have done this on three different Quads (all using Bumblebee motors, btw great motor) and have not broken a single prop in over a year!!  APC props are made well, very solid and sturdy. I suggest everyone do the same, as it will save you tons of cash on replacing props and most of all, repairing your crashed Quadcopter!

Hi,

that was a suggestion, In my case i had the motor's turned by a friend on a lathe to accpept standard propellers.

That is proprietary design, which locks the prop on to the adaptor. but spares are difficult to get.

Infact i flew on a broken prop for many days untill i got the original.

still have the old props

Seems like a preety weird idea.but anyways thanks
