This is probably the third time I have said this, but a 1512 1.5Y would be nice. Better hurry up before the 1.5Y tekin motor gets the call, but I would much rather have a motor that matches my 2650 in appearance. The 1518 1Y will not be the same, as it will draw more current than a 1512 1.5Y not to mention that it will be quite a bit bigger and heavier.
