Did you test the throttle channel on that receiver on another plane?

Which ESC are you using? Does it have an on-board BEC?
yes, I tested the throttle channel on another plane; it works perfectly.

That means the negative and positive connection from the battery to the ESC are good.

The fact that the servos move also means the signal wire connection is good.

However given you are not hearing beeps, either ( in order of likelyhood ).

- One or more of the wires to the motor has been disconnected or has a bad solder joint
- One or more of the motor wires is cut or broken
- The Throttle range is not sufficient enough to arm the ESC.
- The ESC has been damaged

When faced with the above my first move would be to REMOVE the heat shrink from the motor connectors and check continuity with a meter between the motor wires and the ESC circuit board one at a time.

You should have installed bullet plug connectors between the ESC and the motor.

Start by disconnecting these and putting a meter on a plug and the solder point on the ESC.

If you fail to get continuity you've found the problem.

If this works, pull the motor, hook it to the ESC, and check the continuity between the motor itself at each wire's entry point, all the way back to the ESC.

Any failures undicate the problem.

If this works, time to get a new ESC.
