## :exclamation: About
π‘ For the upcoming v1.16 release, we are asking the Commuβ¦ nity for flight tests. This issue will be used for keeping track of all the tests from the Community.
If you're unsure about upgrading, please read the preliminary release notes on the PX4 docs. Pay close attention to the Upgrade Guide before deciding if v1.16 is right for you.

## β Why we need flight testing
π Thousands of people around the world depend on the stable release of PX4.
ποΈ Before every major release, as much testing as possible is needed to ensure that our release actually works!
π― Simply said, **more testing = better release**
π€ We would like to encourage every community member to join us in improving PX4!

Release Blockers Discussion
ESC Calibration Issues (PX4-Autopilot #24635 ): PR was updated to address discussion feedback from the last call, and is waiting on testing for @AWilkins_Ascend
Geofence Breach: Reported by Gerald during flight testing on Pixhawk 6X RT
Geofence breach behaviour different than with 1.15. Hold/Return happening behind geofence. If I recall correctly in previous PX4 versions Hold/Return happened before reaching Geofence.
RC Docs : Some boards have hardware limitations that need to be covered per board. These include SBUS, DSM, and IO inconsistencies, which we need to address. @hamishwillee we need to discuss on a call with @dagar letβs sync via discord on dates/times so we can draft a plan.
