MS Flight Sim '04 interface - Futaba 4VF-FM72 interface to MFS

[Bob-OP]

I would like to purchase an interface cable for a Futaba SkyPort 4 (model 4VF-FM72) to Microsoft Flight simulator 2004. This interface (USB or serial) would replace the joy stick and providing me practice with my RC airplane flight controller. The Skyport controller interface plug is round and has 6-pins. Thank you.
