Hello, I am building the Versacopter v2 using the Graupner MZ-12 combo with the GR-12L. I am aware that they came factory bound but this being my first quad build i was eventually going to run into problems. As i was going through the RF settings i scrolled down to "RX bind" and pressed the "enter" button rather than the "escape" button and it seemed to have unbound? i have tried pressing the button down on the receiver until there was state of change then pressing enter on "rx bind" on the tx multiple times in attempt to possibly rebind the receiver and the tx. But yet still no luck, any ideas(or solutions) will be greatly appreciated!
