I’m having issues with range while flying my nano qx. It only happens when outside but I fly in a wide open field. At around 40 feet I lose connection and it either continues on the path it was on or all power is lost. Either way it ends up falling out of the sky 95% of the time. The other 5% I regain connection because I run towards the quad just in time to save it. I am using the radio that came with the qx. I already upgraded the motors to the Rakon 6mm and to the picnic quads folding frame. Would getting a better radio or a different control board solve this problem? If so which one would be best? If not what else can I do?
