Go with a 2215/2Y and 10S lipos. As for ESC, any good 10-12 (Even 15S) esc can do the trick. If you're going to stick with the mechanical brakes, you can get away with airplane esc. I have a Jeti Spin200 for sale if you're interested. They work great with pistol grip radios and all you need is the program box for it. You'll still be faster than the gas version and you'll have a more efficient running set up. One other member in the forum converted an HPI Baja and there will be another member doing one as well.
