Hi Spacefanmick
Pretty sure a matchbox will work with a Futaba system. As far as the Skywolf jet is this a jet large enough to contain a smartfly power expander? I would use the power expander before using a lot of match boxes. The expander will regulate voltage, has the ability to match servos and allows the use of heavy duty wire comming off the batterys and switches because it has deans connector built into it and also allows for the use of 2 batterys powering it up. This would free up at least one channel in your reciever also.
Good Luck
Mel
