Doing my Homework for Twin Mamba Monster flux.

1521 1Y is 1580kV, like the CC-neu 1520. It can handle 60 000 RPMS and a lot of power, so you just need a high voltage ESC to run it at your insane speeds :D :D :D
7 or 8S with the 1521 1Y should give you plenty of speed.
Keep in mind that many people use the 2200kV on 6S, you can as weel us the 1521 1Y on 8S with the same motor RPM, but a lot lot lot more TORQUE :D :D :D
