First let me say I'm mostly a gas engine flyer so I'm not the brightest blub on the tree when it comes to electric motors. Bought a Emax 2822 1200 KV motor and 30AESC. Plugged in motor, put the lead from the ESC into the throttle port on my receiver, turned on my radio and plugged my 3C 2200mAh li-po. ESC beeped 3 times then continued to make single beeps. It looked like the motor was trying to turn over but couldn't. It was a new battery and had not been charged as yet when I tried this. Could that be the reason or is that motor a peice of junk. Thanking you in advance for any help.

What kind of radio do you have? If it's a Futaba, reverse the throttle channel.

I,m using a Hitec Aurora 9 radio

ESCs need to learn the full and closed position of the throttle signal. This should be explained in the ESC's instructions, if you don't have the instruction sheet try this.......
Firstly, secure the model so that it can never pose a danger to you or others if the motor starts unexpectedly & keep your hands clear of the prop at all times. Turn on the transmitter and set the throttle stick to full throttle - power up the model and when you hear the first beep from the ESC close the throttle, an OK beep will be heard - advance the throttle & all should be well - if not, reverse throttle on TX and try again. If you find that the prop is running in reverse, simply disconnect and swap any two wires to the motor. You will also have to check other ESC parameters such as timing & cut-off voltage, which may be a problem if you don't have the instructions, although if it's a new and unused ESC it will be set to default values which are usually OK.

Hope this helps

Figured it out. It seems the throttle in the off position was set way too high and ESC was cutting off. Lowered throttle on my radio and all wokks fine. Thanks for all the suggestions
