Think what you're finding out is there are very few that have actual experience setting up a dual system like you're trying to run. The lhs guy obviously doesn't have any experieince otherwise he would've told you to pull the red wire in the esc lead from one of the escs so it wouldn't provide power to the rcvr since only one esc needs to do it.


I'd call Castle support and ask them if they've ever really done this and what the pitfalls are, that may be your best source of info. They like to help and this is unusual so I'd be surprised if you couldn't find some help.
