As you guys know, I was so desperate after 1.6.8 firmware upgrade and I was loosing RC signal within 40m-60m .. But After 1.5 months finally solved it permanently.. Here we go!!!
In my method, Basically you need to put 1.6.80 firmware to your RC and also you need to put 1.5.70+ to aircraft...
After install of the latest software, Im getting an RC signal lost in red. Is there a fix for this? Everything seemed to download ok and install. Now what?
