I need to know exactly which brands of receivers are compatable with JR. I know Futaba & JR don't mix, but HiTech & Airtronics will work with both, is that correct? Or is it just certain ones from those two brands that will work with JR? I have just placed an add in the marketplace to either sell or trade a couple of my futaba receivers and I need to know what will work for sure with my new JR in case I end up getting a trade offer. Thanks in advance.
