RE: JR Receiver Futaba Servos???
I don't think this will work. JR is positive shift and Futaba is negative shift. However, this is a question you really need to ask the equipment manufacturer about. Earlier this summer, I was thinking about combining my Airtronics receiver (positive shift) with Futaba or Tower servos. The folks at Tower informed me this won't work. HiTec RCD makes servos which will work with either shift. I don't think it is simply a matter of shaving down the lug on the Futaba connector. So, Tower, Futaba and HiTec RCD will work together with J-connectors and JR, Airtronics and HiTec RCD with Z-connectors will work together.
