Help recommend a cheaper 1000kv motor

[Overdriven]

I don't know all of the particulars, and don't feel like using the speed calc at the moment to see how much difference it'll make, but Ofna does make a 48T spur for the spider diffs. Part #OFN19345

Edit: I did just visit BrianG's site to figure out the diameter of the Spur gear and it says the 48T will be 1mm bigger in diameter than the 47T. But thats diameter, in reality the spur will only be .5mm closer to the pinion.
