Do I need to Program my 25a ESC?

When I start it up it goes "b b b"

thats normal, right?

What does "Break" and "no break" mean?

Thanks for the help.

Yea it should go BI BI BI not BIBI BIBI BIBI. I'm not sure what break does ,I think its a shut down for when your battery voltage gets to low.

Interesting- Thanks!

The brake feature is used to actually stop the motor as soon as the throttle input goes to zero or is reversed. This is mainly used in RC cars where the motor doubles as a brake. On RC helicopters, this features is usually disabled. On start up you should hear three short beeps if your throttle is all the way down (and its trim).
