Connected the ESC to a 4400 Kv Brushless motor. Using a HK 6 Ch Tx/Rx. Getting a continuous beeping sound. How do I get this thing to work?

I need help URGENTLY.

The manual can be found here

See if this helps you.

Two thngs
1) Are you using a 3S??
    A 4400 kv motor might pull around 40A at 3S and maybe thats the point, try a 2S  for that matter.
2) Check your channels on reciever if they are on their respective places. When you connect servo to the ESC's place Beeps are observed.

Vikas, this is the second time that you have rescued me. Thanks mate, I owe you one. Grateful.

Traxx - thanks, however, all connections were in place.

Using this to control the thrust motor of the Griffon 2000 Hovercraft. More on that later. Project nearing completion.

Your welcome Sir.. let us know when you're done with the project.
