Q for Castle REP about my 1717

[Bondonutz]

I've recently installed my 1717 that I purchased form Horizon Hobby and also recieved a 5mm rotor from you folks(thank you).
What I've recently realized is my motor must be a Heli version ?
It has open endbells and 2 flat spots on the can and the KV is 1500 not 1580.
The open endbells was no problem, I sealed many NEU's befor. The flat spots, no problem dont care.

Any comments on this ??
