so i have done the fcc hack and flying my drone in the ce country, the trouble i'm having is when i connect everything up i get 2.4ghz as default and so have to choose custom and then choose a 5.8ghz number and then i can fly in 5.8ghz. but then when i switch off and reconnect the aircraft iit goes back to 2.4ghz as default?. is this correct i just wish it would stay at 5.8ghz?.
