^On that note;-
If you could manage an 1800kv and 1600kv motor in a 1515 can, then there would be ALOT of guys who would snap them up for their traxxas MTs; the 1518s were a hugely popular upgrade to the regular 1515 1Y motor in the brushless emaxx and erevo. The trouble with the erevo however is that the 1518 motor is just a bit too long to fit, so guys have to trim the rear shock tower for clearance; 1800kv in a 1515 can would be brilliant, assuming you could get the same kind of efficiency as the 1518 motor.
I think thats the only niggle with the NeuCastle motors at present- if you want a lower kv rating you have to go to a longer motor- having different kv ratings in the same can size would be a real hit, Im certain of it. Heck, you might even persuade traxxas and hpi to get onboard and offer different versions of the motor with their BL trucks, take advantage of the guys who are sold on the lower kv & higher voltage way of thinking
