Yep, that's why I don't encourage anybody to go 2s. It's a bit counter intuitive. You're brain thinks 2 cells is cheaper than 4 cell but to race........you need 2s2p so 4 cells. You need a sick motor. You need a bunch of amps. Amps are the devil.

Darins one cell boat draws approximately one p'scillion amps. That's p'scillion. Not b'scillion. Huge difference.
