Copter-4.3.6 released!

Copter-4.3.6 has been released as the stable/official version and can be installed using MP, QGC or can be directly downloaded from

The changes vs 4.3.5 are in the ReleaseNotes and also copied below.

  1. Bi-directional DShot fix for possible motor stop approx 72min after startup

This fix is critical for vehicle using bi-directional DShot that could be flying 72min after startup because the chance of failure is about 30%.

Note that this does not affect the more common regular DShot which many vehicles use. Only Bi-Directional DShot (which provides RPM feedback from the ESCs to the autopilot) is affected.

As always thanks again to our beta testers for their help in testing this new release!

Hi @kangdeugil,

Txs for the report. I tried to reproduce the issue in SITL (with Copter-4.3.6) but I could not. This doesn’t mean there isn’t a problem, it’s just that I couldn’t reproduce it.

The log you’ve posted is very short. Maybe this is from the wrong flight?
