Hi all, I'm trying to find a controller for a phantom 1 (or at least I think is a phantom 1). I'm not positive if I have the Phantom 1 or FC 40. Can someone explain the difference? I have the model p330D and after the serial number has V2.0.0. I think I've narrowed it down to the FC40 but not positive. Anyway, I need a controller for it and I see there are different frequencies (2.4GHz or 5.8GHz). The DJI store only lists the 5.8 GHz controller but I would rather be certain before ordering. Any thoughts would be greatly appreciated.
