Correct, unless the ESC has programmable functions that allows you to disable the BEC (most don't), you have to pull the red wire from the servo plug like pilotpete2 said. Pull the red wire out of the plug, or better yet, pull the red wire out of a servo extension and plug the ESC into the extension. Try not to cut the wire if you can possibly help it as if you ever move that ESC into another plane and need the BEC, you only have to slide the red wire back into the plug.
