Dear all. I am stuck and pretty frustrated. I bought the first phantom that came out. I wanted to upgrade the board and install the zenmuse h3-2d. After the upgrade everything seemed to work, but adding the lever to the transmitter caused the transmitter to go dead. So i could not fly. I decided on buying a new phantom (for the transmitter and parts). However, this transmitter disnt link with the old phantom. I then installed the upgrade kit and zenmuse on the new phantom. Everything seems correct, But i can not start the motors of the phantom!!!!! Anyone, please help!!!!!
