Newb considering a BL/Lipo 8T conversion

Hmm...might be able to get the best of both worlds, just read the thread about a 1500kv motor to be launched by CC.....might be worth waiting to get a MMM ESC with a Castle 1717 perhaps? Still with Hyperion 4S 6500mah....

Worth waiting for, or will the 2200kv be more than capable of what I want? I guess the power will be fine with the 2200kv for my needs, but would the 1717 1500kv be more likely to get longer runtimes with the 4S 6500mah?
