You are almost there. Once you have set H3 2d exit the programme, then launch the standard Phantom Assistant. Under Basic tab there is now an X1 option where you calibrate. Clearly you can't do that right with your Tx in bits... :ugeek:
The full steps are:
- Download the Phantom Tool package from Dropbox & Unzip somewhere convenient.
- Connect your Phantom2 Vision to the computer via USB
- Power Phantom & turn on Tx
- Start the Phantom2-Tool you just downloaded.
- Select the H3 2d box (not the vision one).
- Close tool
- Start DJI Phantom 2 Assistant_1.08
- Got to basic Tab and select Start button to calibrate X1 (7th Channel).
- Click Finish.
Note that you can no longer move the gimbal in your Phone app, only on the extra lever your have fitted to the UPPER potentiometer. If you want to go back to using the phone to control gimbal, load the Phanom2-Tool, re-select P2 and close.
