Not to point fingers are other components, but it sounds like you might have a radio issue there. If the ESC is not seeing a valid radio signal, it won't arm; but the yellow LED is solid so it is seeing some type of radio signal.

Do you have steering control on the vehicle?

If you do have steering control, try swapping the ESC and servo in the receiver; meaning put the speed control in the steering channel and the servo in the throttle channel. Power up the system as normal and see if the throttle trigger controls the servo. If it does not control the servo, you have a radio problem. If the servo does work, then the radio system is functioning correctly.

If you do not have steering, then it is either a radio or speed control problem. If you have a multimeter/voltmeter, check to see if the Monster's BEC is outputting voltage correctly. To test it, pull the speed control's receiver wire from the receiver and put your meter probes on the brown and red leads. You should read around 5.5 volts, if it is lower than this then it is an ESC problem. If it reads correctly, then it is most likely a radio issue.

Try these things out and we'll see if we can narrow this problem down.
