DBVS I thought that this problem only happened to me, I don't know how to fly in 3D but I do know how to fly perfectly hovering and every time I fly it it breaks due to that failure to change only mode, precisely these days after a year with this model I'm asking Eachine for a solution, but they don't tell me why it fails, all the broken parts I've had is because of that problem, sometimes the second the flight starts it changes, other times I spend a battery and don't It happens, the last time I fixed a flight, the second flight in less than 1 minute changed and I had a strong blow, and today the spare parts are expensive or very expensive, apart from the frustration of breaking every time I fly it, I have the Xk k110 and the Xk k 130 and what happened with this model never happened to me
