When i first got my DJI Phantom 2 with the H3-2D Gimbal everything worked fine at first, then it seemed that intermittently the X1 channel wouldn’t calibrate right. I could sometimes get -1000 to 1000 movement but to get that movement i had to quickly move the lever and try to hold pressure on the base of the Camera movement lever to get it to move the whole range. This was frustrating to say the least. At the first occurrence of this issue i took the Remote Control apart to see if it was just the lever not making contact with the pot on the PCB Board. The pot is the little device that turns the movement of the lever into a signal which in turn moves the camera once received by the Phantom.
The first time this happened i messed around enough to somehow get it to work again. I just had this same thing happen again and finally figured out how to fix it.
Note: I know the RC Assistant is only used to calibrate the normal control channels and not the X1, but this in my opinion is what causes this fix to work!!
- Turn on the Remote Control and launch the RC Assistant Software (not the Phantom 2 software)
- Plug in the Remote Control with the supplied USB cable
- Calibrate the normal Control Channels. (after step 1 is complete read on)
- After you move the control levers in all directions don’t click Next yet. Move the X1 channel to both extremes a few times slowly. For this step i had the remote taken apart and moved the pot (the little electrical box with a philips style yellow top) with a philips screwdriver, but you should be able to achieve the same with just moving the lever. Once again: I know that the X1 channel isn’t calibrated officially at this point but it needs to be moved at this point just like you would during a calibration.
- Click next and finish the calibration.
- Turn off the remote control and quit the RC Assistant Software.
- Unplug the remote control.
- Plug in the USB cable into the Phantom 2 quadcopter.
- Now start the Phantom 2 Config App (the one used to upgrade firmware for the actual Phantom 2 quadcopter).
- After turning on the Phantom 2 plug it into the computer.
- Calibrate the remote control again.
- Calibrate the X1 channel.
Now you should have a working X1 channel again!!
These are the steps i followed to get my X1 channel working again, I hope they worked for you as well. I would have had to send my DJI Phantom 2 with remote control and Gimbal to the store where i bought it from and waited for them to send it to DJI which takes weeks.
If this helped you leave a quick comment or shoot me a quick email.
