PowerExpander 14MZ questions
There have some reports of problems with the Futaba FASST RX's and some non-Futaba servos because of the 2.7V output signal level of the FASST RX's. I bought a PowerExpander 14MZ for my R6014FS receiver to make sure that this is not a problem in my jets that use all JR digital servos. I have used a PowerExpander Sport with the 7-channel FASST RX in a jet with all JR digital servos and it has worked out fine, so I'm assuming that the PowerExpander 14MZ will work with the R6014FS. Has that worked OK for those who have tried it?
My second question involves powering the PowerExpander 14MZ. I know that it has two power inputs and will select between them based on input voltage giving you a redundant power supply. However, I am currently running a single Fromeco regulator with a 5-cell NiCD pack in the jet I want to put this combo into and I'm completely satisfied with that combination and don't want to add another battery pack and regulator. I'd also rather not have to go out and buy and install a SuperReg or Turboreg at this time - too much expense and weight, but also I'm not comfortable changing that many variables at one time.
How can I power the PowerExpander 14MZ from a single source? On the PowerExpander Sport, I simply "y'ed" the power lead and plugged it into both sides - but this doesn't have the input switching capability...
