RE: Whick Power Expander to Use with new JR 12X
I have not seen this receiver yet but it should work just fine with the PowerExpander MZ. There is nothing about the MZ that is Futaba specific. We will be coming out with a new PowerExpander 12 channel with Ignition Cutoff and a new PowerSystem 12 channel similar to the PowerSystem Eq6 versions but with no servo matching. These probably will not be out until mid summer though. Let me know if I can be of any further assistance.
