Copter-4.4.0-beta5 available for beta testing

Copter-4.4.0-beta5 has been released for beta testing and can be installed using Mission Planner or QGC’s “Beta firmwares” feature. Alternatively the binary can be manually downloaded from

Changes vs -beta4 are in the ReleaseNotes and also copied below.

  1. Autopilots specific changes
    • SIYI N7 support
  2. Bug fixes
    • DroneCAN airspeed sensor fix to handle missing packets
    • DroneCAN GPS RTK injection fix
    • Notch filter gyro glitch caused by race condition fixed

This is very likely to be the last beta before the official 4.4.0 release. In fact we thought it was ready for release but then discovered the Notch filter gyro glitch issue and wanted to include this fix.

All feedback is very much appreciated!



Thank you Randy for all your’s and the team’s work to allow me to have fun and enjoyment with these contraptions
