I think I have a reciever problem I was trying to see if the esc I have has a esc built in and the motor didnt turn or servos but esc kept on beeping. I tried another esc and the servos worked and motor didnt turn, I also tried another motor. Can anyone help. I really wanted to see if first esc has bec built in now there are other problems. Who knew. Thanks Joe

Shurlock,
Please start by telling us what equipment you are asking about.
Thanks,

Need more info,

Sounds like you are not arming the Esc.
Remove the prop to be safe.
Plug in the esc with throttle stick Down.
You should hear a beep, now raise the
throttle stick to full Throttle. Should beep
again, now lower throttle stick. You should
hear a serie of beeps (3or4) depending on
your battery size. The Esc should be armed
now.?? Slowly raise the throttle stick, motor
should run.

If the above did not work, try reversing your throttle [servo reverse switch] on your transmitter since your servos are working. Then redo the arming procedure.

Usually instructions come with things you buy, unless buying used junk.
