I finally bought the P2 v2 with the H4-3D gimbal combo (and a Black Pearl FPV system with upgraded pentalobe antennas). I got it yesterday and installed the iOSD Mini, the anti-interference board, the H4-3D gimbal and the ImmersionRC 600mW transmitter for the FPV. I then performed the software/firmware update of the iOSD Mini, the P2 controller/transmitter and then Phantom 2 itself. After all of that, the only issue I currently have is that my gimbal won't tilt very far. Maybe 10-15 degrees max. It doesn't go straight forward or straight down. It starts out around a 45 degree angle and moves maybe up 5-7 degrees and down 5-7 degrees with the tilt wheel on the transmitter/controller. Anyone know why this might be? How to fix it? Again, everything is brand new and I just got it yesterday and I've been doing a ton of research before buying and putting everything together, so I don't believe I did anything incorrect, but apparently I'm missing something here. So, I'm trying to do research on this before anything else to verify everything is good or if something is broken and I have to return it. I do have the HERO3 Black in the H4-3D, but I don't think that is the issue. I know the HERO4 is heavier, but that still shouldn't make the gimbal only move about 15 degrees instead of the full 90. I could understand if it wasn't centered or something, but it shouldn't limit the movement like that. My guess is it is some sort of calibration issue that I missed. I followed the DJI instruction guides and all of the info from inside the box, so not sure what I missed. I know that I have to calibrate the compass before flying it, but that shouldn't have anything to do with the gimbal. So, now I'm trying to find videos on calibrating the controller/transmitter or the P2 itself. To me, something has to be throwing it off and limiting the movement of the gimbal. Any info would be helpful. Thank you! Mat G.
