IMPORTANT NOTICE – HEXH2O PRO v2 owners using PAYLOAD RELEASE:

Posted on July 5, 2017

UPDATE 11/7/17
We can now confirm DJI have acknowledged the bug and have confirmed they will be addressed in the next N3 flight controller firmware released.
———-

We have found that the latest version of the DJI N3 flight controller (version 1.7.1.5) when used with the channel expansion kit (used for our payload release system) can result in the servo becoming unresponsive when trying to activate the payload release.

After testing we believe this is caused by the latest onboard SDK support released with version 1.7.1.5. This issue has been reported to DJI.

We are recommending that HexH2O PRO customers using the payload release system should keep the N3 flight controller on version 1.7.0.0 until DJI have addresses the issue.

You can downgrade the N3 firmware version via the DJI Assistant Software.
