Poorwboy, Sorry for such a departure from your Cirrus servo problem. I hope you can see how it happens. I'd jump off an start a new thread, but all the action is right here so what am I to do?

P-40 Driver, Yes I am running a single battery into each RX right now. Yes I will lose half my system and have to land the plane with limited control. Throttle control remains with the servo on one RX and the engine cut-off on the other. Complete separation of each system was more important to me than dual battery on each RX. I am open to the options here and have looked at the SmartFly product. I had a long talk with Don of Don's Hobby Shop in Salina KS regarding this product. He said he could make a lot of money selling them along with all the PowerPanels on the market but he won't because they routinely fail. I was not encouraged. Don does endorse the use of MatchBoxes for multi-servo high power applications, and I can understand this because each matchbox only deals with a single control function. It does not effect your overall power supply to the RX. My friend Pierre, who is an electronics expert as a profession, is after me to run the two RX off a common battery bus with diode isolation. I may do this. What has stopped me from the bus idea is that I want to know what protects this combined battery system from a high amp draw down either RX path? I am open on this and would like to hear your recommendations. Leo
