All of our PowerEpanders and PowerSystems, no matter when they were manufactured, are compatible with the Futaba FASST receivers, in particular the 14-channel 6014 FASST receiver. We have always accepted a servo control voltage down to at least 2.4V, most of our systems will support a receiver voltage down to 2.0V. Also, on all our PowerExpanders and PowerSystems, except the PowerExpander Eq10, we boost the servo control voltage on our output to 5.0V. On the PowerExpander Eq10 we boost it to 3.3V.
