I just had this happen yesterday...found drone flies fine using phone..opened the transmitter and the wires under the stick on the Potentiometer (yellow,black,white) were not soldered well. All that held them on was the glue they use to reinforce the wires ...soldered them back on and it works great now...u can confirm this in the app by binding it all up and watch the input the rudder should show +57ish to -57ish left and right max stick input..if the reading doesn't change or is stuck at a constant #...the wires r probably broken off

Thanks for the information I opened the controller under joy stick and found one wire not attached and two nearly broken so I resoldered all it works perfect now.
