Can you buddy box a dx7 with a dx5? I have a dx7 bound to my planes and purchased a used dx5 so i could get some of my friends interested in the hobby by buddy boxing. I followed all the instructions supplied in the dx7 manual but i couldn't get the dx7 and dx5 to work. My cousin had another dx7 on site and everything worked properly when i set both the radios to buddy box settings. So, is it possible to buddy box a dx7 with a spektrum dx5? If so what exactly are the steps i need to take to get the two transmitters to communicate properly?
