First off, don't get the GP4300's. They don't hold there voltage well. The IB4200's are the way to go. Either them, or the 3800's. The for 7 cells, I would not choose such a high KV motor as the 7700. That would be ~65,000 RPM's. I would choose something like the 4600 if you might run more cells or LiPo, or the 5700 if you wouldn't run any more than 7 cells. Remember, even though the CC motors are rated for high RPM's, there still gonna run hot and inefficient at such high RPM's. Try and stay around 40k for most BL motors, the CC motors, 45k would be good.
