Why on this Eflite Viper if we plug the ESC into the throttle port it will power up fine but if we use a external BEC with the same voltage output the receiver will not power on. Its the AR636. What am I missing here?? This is a new plane he just got today. Thanks

I've had similar issues which were resolved by linking the BEC Neg wire to the ESC Neg wire
