Just spent an hour soldering all the necessary hardware to this esc and programing it with the program card and can not get a beep out of it nor does it turn the electric motor. I troubleshooted the circiut between batteries and other escs and motors and it is in fact the esc that is the prolem.
 
any ideas why I can't even get a beep out of the unit?

Battery hooked up the right way round?

Also, the ESC doesnt beep, the beeps come from the motor.  Grab your motor / esc connectors and give them a good pull to make sure the wires are actually soldered in and not just held in with solidified flux - very common when soldering wires into a tube like the bullet connectors.

Does the receiver fire up and move the servos?

Yes Dave, the servos do work when the esc is plugged into the receiver. The esc gets warm right off the bat as well.
 
I will ck my solder joints just after my cup of coffee.
 
Thx

Strike that one up to luck ??  LOL

Possibly it just wasnt arming properly, maybe the throttle range needs setting - ie, drop the battery off, hit full throttle, power up til the first beep ( bout 2 seconds) then drop to 0 throttle.  This will set the throttle range properly so the ESC knows the exact positions of full throttle and idle. If its not detecting idle properly it wont arm. If it doesnt know full throttle properly it can overdrive and do strange things at full throttle stick (like motor screeching to a stop)
