No I haven't , but now the tilt only works sometimes even tough the motor doesn't seem to have any problem , looks to me like there is a problem with the app
I have the same issue with the camera and when you tilt the camera all the way down the motor stays on ,they should release a firmware update to correct this.
I already have a Gamesir 3GS controller and I'm not able to control the drone , they should make a firmware update to allow this controller to be used.
