I have a DJI Phantom 2 with H3-3D gimbal, an FPV system (Storm) plus and iOSD. After brining it to some experts, they got it working. I loaded a program called “DJI Assistant”, and in the BASIC part/gain screen, I selected “default”. After this, I could not START the Phantom. I reconnected the Phantom to the software, and got an error message saying “Motor Start failure cause by TX stick(s) mid point error too big”. The instructions on how to fix this were beyond me – very confusing. I updated the firmware (top one), and I changed the gains to be somewhat higher than the default, power-cycled the remote several times, and eventually got to where the motors will start again. BUT – NO FPV. I have jiggled the wires, checked what I can, but get no output, it seems, from the Storm FPV transmitter, which was working fine before. Is there something I may have done in this software program do disable the FPV? HELP!
