There is no specific place the Castle UBEC needs to be installed, but you do want it where it will get a little air cooling.

You will need to solder the power leads of the BEC into the battery connection. I think this comes with an EC5 connector, and the pins can be pushed out of the housing (they just snap in). Push the pins out and solder the BEC power leads to them (see example in the pic, the green circuit board is the BEC in this case). You will also need to pull the red wire from the ESC lead to the RX. Take a hobby knife and gently insert under the locking tab in the connector and lift up, then pull the red wire out and secure it with tape. The Castle RX lead then plugs into the RX in the battery/bind port depending on your RX.
