1.  If you haven't already, please setup your multirotor and make your first flights using the instructions in the Hoverfly manual.
HoverflyPro Manual

 

2. Download and install the latest version of the Hoverfly Setup Client:
Hoverfly Setup Client

 

3. Update the firmware on your HoverflyPro to the latest version using the Firmware Update Client
Hoverfly Firmware Update Client

 

4.  Open the Setup Client and click on the Camera Params Tab

7. Zero the Roll Calibration, Roll advance, Tilt Calibration, and Tilt advance values.  Set the Roll center value  to 1500.

Also, open the Roll Travel and Tilt Travel Sliders Fully.

8. After removing the propellers from your multirotor, connect the the battery to your main power connector and turn on your Radio.

 

9. Click the camera mount on check box.  At this point your camera mount should become active.  The roll should go to the 1500 position you set earlier and you should be able to move the tilt with your transmitter control.  The mount will not provide any compensation yet.

10. Set your multirotor on a level table.

11. Manipulate the Roll center (in the setup client) and Tilt control (on your radio) until the mount is perfectly level in both the roll and tilt axis.  We recommend the use of a bubble level for this.

12. Prop up one side of the landing gear of your multirotor so that the roll axis is approximately 30 degrees from level (the specific amount is not important)

13. Adjust the roll calibration value until the mount returns to level. Use negative values to get the mount to travel the opposite direction.

14.  Repeat steps 12 and 13 for the tilt axis.

15. If your camera mount does not keep up with the movements of your multirotor, try adding Tilt Advance and Roll Advance.  This will help speed up the movement of your mount.  Keep in mind that too much tilt or roll advance will result in a mount that wobbles around a lot.  Use the least amount of tilt or roll advance required.

16. The HoverflyPro camera compensation also has travel limiting for the Roll and Tilt axis.  Move the Roll/Tilt Travel sliders inward to reduce travel.

17. Be sure to SAVE YOUR SETTINGS!!!

    Hi guys, just a matter of curiosity regarding the roll and tilt advance function.  With respect to the speed of the HFP gimbal control reactions is the lowest roll or tilt advance setting operating at the fastest possible HFP ability?  I probably have not got a proper understanding of how this works at this point so forgive me if this is a dumb question.

    Higher Advance numbers result in faster servo movement. However, numbers that are too high will also result in jitters and camera mount wobble.

    Advance isn't a setting that makes the HoverflyPro go faster (it's going as fast as it can all of the time). It's a setting that tries for force the servos to respond faster to the commands the HoverflyPro gives them.
