So I just got my Phantom 2 v2.0 w/ H4-3D gimbal. After installing the gimbal I've noticed that the gimbal only tilts 45 degrees at a time(not full up and full down tilt). Now, I know this is how it comes from the factory, but when I try to re-calibrate my transmitter sticks so that I can get full 90 degree tilts, my computer doesn't talk to the transmitter. My computer recognizes when I unplug the transmitter but that's about it. It is a PC, which might be part of the problem, but I'm not sure. So if anyone can help, let me know what I'm doing wrong! Thank you!
