I have had the phantom 2 for some time now, and I recently picked up the zenmuse h3-3D for my GoPro hero 3+ black edition. It worked perfectly at first, but after a lot of uses, the tilt function that I could control from the remote stopped working. The gimbal remained fully functional, but I could not control the pitch with the attached switch on the remote. I have the version without the knob on the top, but the one with the lever thing on the back of remote. The remote does not have a battery status indicator. When this first occurred, the gimbal would tilt about halfway to straight down, and then shoot back to the level position, but now it isn't responding at all. I'm not sure if it is a gimbal problem, a remote problem or a drone problem. Thanks for the help in advance.

Try this and let us know....

Thank you so much for the help but it didn't seem to work. The calibration was successful, but the gimbal still isn't responding to the lever.

While trying to find another way to fix the switch (which i did), a new problem arose. I just received this message in the PT2 app.
"Motors Start failure caused by TX stick(s) mid point error too big
If the TX stick(s) mid point error is too big, Motors Start will fail when you execute the Combination Stick Commands (CSC) and lead to the aircraft will not takeoff.. And the LED will blink Red four times per second continually to warn you.
TX stick(s) mid point error too big can be caused by the following reasons:
(1)        There is TX stick (except the throttle stick) not at center when power on the autopilot system.
(2)        The TX sticks has been trimmed, which leads to the large deviation of mid point. For example, the SUB-TRIM has been adjusted for Futaba transmitter.
(3)        The TX stick(s) travel has larger asymmetry.
For the reason (1), please put all TX sticks at the mid point, and then power cycle the autopilot system to re-record the mid point. If the problem continues, that can be caused by the reason (2) or reason (3), you need to adjust the output range of your TX, and then use the Assistant Software to   redo the TX calibration. Please carry out the following procedures.
(1)        Connect to the Assistant software, click Basic-> R/C-> Command Sticks Calibration, and push all TX sticks throughout their complete travel range to see if any stick cannot reach its largest position.
(2)        Adjust the largest travel of TX stick until the cursor on the Assistant software can reach both end positions, according to your TX manual.
(3)        Power cycle the autopilot system, note that power cycle is required.
(4)        Redo the TX calibration according to the Assistant software."

What do I do.

Never mind. Just recalibrated it through the app, and fixed all issues. Thank you for your help though!
