Ed,
Wow . . . now don't I feel silly. I just realized you are Tech-Aero. Somehow I was under the impression that Ed Alt regulators were separate from Tech-Aero. Anyways now I get it.
But I wanted to clarify something . . .
The only component I'm really talking about here is the VHVBEC. I use a standard Jeti speed controller with no BEC. Normally I plug the VHVBEC directly into the RX battery port on one side and a 10S battery tap on the other side. This VHVBEC does not need to be connected to the speed controller other than the 10S tap. Forgive me if I am stating the obvious; I just wasn't certain from your last comment if I had been clear in how I was proposing to use this setup. So my dilemma is finding an independent UBEC that has a reverse flow blocking feature built in, and I would be happy to send you one these VHVBECs for dissection if that is of interest.
In either case thanks for the help, and look for my order later today
Joe
