I have already talked to Roland about using his MSFF2 Hack with the Copley 423 DC Brushed Servo amplifiers http://www.copleycontrols.com/Motion/pdf/412.pdf
"I don't think it is possible to interface the servo amplifier to the MSFFB2 stick.
It is a control system based on current feedback, and uses full bridge PWM to control the motor current. Your servo amp uses 0~10V control input, and I did not see bridge current sense output. So I have no idea how this could be interfaced with the MSFFB2 hardware. "

So now I am looking at Controlling the 423 amps with an Arduino by suggestion of a copley engineer. The poster of this video André Pointner has had some success converting a WH to FFB.
Using X- Sims TripRodriguez all so original made some post on the sit but has switched to using a different control system and software for his 6DOF Sim.Software: Ian's BFF Simulation 6DOF
Controller hardware: Thanos TronicGR AMC1280USB and 6DOF extension board I have asked him about h his experiences on his thread but have not received any answer as of yet. I really don't have the money to hire an engineer to come out to the middle of Montana to set this up
