All-righty-then! They were correct, Opjose, you're the man!

I've got one more question to add to this then: Hobby Partz recommended the 40A ESC. With the 13x8E prop this is way undersized. At full throttle we measured close to 70 amps at the battery with a clamp-on DC amp meter (not an inline). I was originally thinking of down-sizing the prop and upsizing the ESC to 60. After going out to the club races today I'm considering a 80A ESC. I understand that the size of the ESC won't drain the battery any faster. Is this correct? And what size ESC would you recommend?

Thanks Opjose!
