Mike, I've had one motor go 11,000 rpm/volt and another go 9,500 rpm/volt. It doesn't matter how fast a motor spins. It'll only spin so fast before it's breaks. Those high KV motors are way less efficient too. The high KV motors are only good if you are absolutely limited to running only with 6 cells or other low voltages. Since you're using lipos, high KV really just doesn't matter - in fact, it'll just run hotter and destroy controllers and batteries.

If you want to run 11.1 volts, get a polyquest 11.1 volt 4400 mah pack. Fits in a standard 7cell location - just a tad taller so you'll have to back up the threads just a little. Or, you can go 14.8 volts 3500 mah. Both packs are the same size. These packs will deliver 1HP easily (700 watts). Just be VERY careful charging them and read about all their safety stuff before you get into it.
