Motor rebuild kits: 1410 and 1415

So how far away are the rebuild kits for the 1518, 1520 and the 1717????
I need a rebuild kit for my 1717 as I want to try it on 8S for a couple packs and then rebuild it with a fresh rotor just in case. Also having bought the other motors too it would be nice to have rebuild kits on the shelf for a rebuild later on down the track.

Almost cringe at the thought of the price for the 1717 rebuild kit. Would have to be way more than what I paid for it. LOL. The rebuild kit for the 1415 is what I paid for my 1717 motor. Sad in a way but can't complain since I got the motor (and few others) for a steal.
