New setup 8xl and 9920

I had a few problems but I got past those. To make things simple I start without an external BEC. I had it solder for it, but just didn't program it with the external BEC hooked up.

I got everything working with 7-cells but have these problems:

1. When I pull the black jumper, and hook up the External BEC the motor doesn't respond, all other servos do (do I have to re-program the speed controller?)

2. I have forward/reverse, no brakes!! How can I get the brakes to work, in the process I fried my receiver, so I bought a new Futaba Magnum 3PM receiver/transmitter. I'm assuming this transmitter is fine.

3. I'm used to the Novak system which has an on/off switch, I notice when I plug in the 2 7-cells, that is will spark. Do I need to worry about this?

Thanks,
Nick
