Thanks. You are a great help. Not even managed to get the rotors spinning on this thing yet - has been driving me crazy. I have checked the 'about' in Settings and it says App Version 2.4.2 and RC Version 1.5.70 - Shouldn't it should say 1.5.30?You can only update the RC thru the GO app. Does the overall status say normal when everything is fired up like your ready to take off? if so, confirm which firmware is installed. Look on the "about" section in the settings menu. Also, make sure your device has internet connection available
