Rob,
I think it does with the Graupner RX but I'm sure Dave will correct me if I'm wrong, personally use mine with JR R1000 10channel PCM rx's , I dont need more (yet). I bought one from Dave two years ago after dumping my 9ZAP, am very happy I made the right choice even if I did have to replace 5 rx's as well, even the manual is pretty well too. Mike
