I ordered another 1717 car motor, 1580kv, 5mm shaft the 1st day of the sale. The email confirmation from Castle said the right thing, the invoice in the pkg said the right thing, but I received a 1500kv air motor.

Shaft looked big - I measured it and its a 6mm shaft (ad says 5mm for the air motor). I was one that waited months and months to get a 5mm shaft for the orig 1717 I ordered during the Black Friday sale 1717 last year. Don't want to do that again.....

I called and was assured it would be straightened out. I've already had email notification of a pkg from Castle.
