Castle 10a bec to 3gx-m???
Can I use an external bec with the 3gx-m (receiver integrated 3gx) it doesn't have a battery port do I tried to use a y and disconnect the power wire from the align esc but whatever port I plug into it stops that servo from working but all others do. Any help.

Not familiar with the connections and connector blocks on the 3GX-m with the integrated Futaba receiver, but in general if you want to use an external regulator with an ESC having its own built-in regulator, you will need to remove the red wire from the ESC cable (leaving the outer two wires intact, as one is ground, the other is the ESC throttle control).

Upon doing that, you need to get the positive voltage output of the external regulator plugged into the spot in the ESC connector from which you removed the red power pin (center pin of the connector). Next, you need to hook the negative (ground) lead of the external regulator to ANY ground pin that's available on the controller connector block.

Doing that, you should be good to go.

Any chance you can post some good, clear pictures of the top of your 3GX-M unit, as well as the business end of its connector block?

EDIT -- I found some good clear pics of the controller and connector block.
