Ha, no biggie. The governor is a mode you can set the ESC to, in which the ESC will try to maintain a constant RPM automatically. The alternative is to tune your throttle curves to achieve that result. Both approaches have strong and weak pionts of their own, and some ESCs have governor software that doesn't work very well. The Phoenix code seems well done, as does that in the Jeti Spin controller. The Ace ESC that comes with the motor-and-ESC-combo Mini Titan works a lot better with throttle curves, on the other hand.
