So I put a Gopro mount on the underside of my Phantom 2. At the same time I disconnected the two gimbal wires that come taped to the underside from where they connect on the inside and took them off. I also took off the canbus, i disconnected the canbus and then threaded the cable up inside and zip tied it out of the way - without re-connecting the canbus. Then I tried to start the Phantom. At first nothing happened at all. Then on the third attempt, the motors started turning, but jerkily and very, very slowly, like a revolution every few seconds. Does anyone know what's going on? Did I mess something up by not having the canbus attached? Is it something totally unrelated and just coincidental? Any help would be appreciated. I'm in Thailand right now on holiday and would LOVE to get some drone pics here! Thanks! Mark.
