Update: Stan C. reached out to me and we had a nice chat on the phone about the plus and minuses of the Revo system and how they would fit into what I wanted to do. After speaking with Stan I gave Don Sweet a call at RCS and talked his ear off with more questions about the Revo and I decided to finally pull the trigger and get a battery setup with the Revo that I will install in the RS3 project I have been working on. See the motive power section for what I’m doing with that.
It looks like I am joining the battery brigade… at least with one engine… for now.
Thanks to all who offered advice.
