Thank you for a reply. The motors I ordered from HK do however have 3 threaded holes on the front of the motor. I noticed that the images on the internet show them without holes, but I can guarantee that D2826-10 do have three holes, at least on the ones I ordered. Looks similar to this: www.link advice, I really wish to install these adapters if they are a good match. Thanks!
No, because there aren't any screw holes on the shaft end of the motor. the motor does come with a 4mm collet adapter to install your prop with. This part is meant for using NTM motors in front of a firewall. The 2826/9 is made to be mounted in front of a firewall.
Sorry mate, but I did not ask that ( center to center distance of 3 holes ). I'm pretty sure that Jose's answer is the best answer in this case (drilling center line is 6mm in radius or 12mm in diameter). Anyway, thanks for your attention !
Arrived nice. should have been included in with the motor. Anyway, can't complain now.

Overall very nicely machined. However, the cross is a bit weak, compared to other sources - it bends at the inner holes quite easily. This is almost not noticeable when actually attached to the motor, but still it's a bit weaker than others.
The propeller mount fit is sometimes very snug, so you have to use the screws to actually drive it onto the motor (by hand it wont go on)
