Just got the qualitywings 787 for p3dv4. I flew on a test flight from Incheon (Seoul) to Narita (Tokyo). But i didn't set the fms completely, i flew with basic heading and altitude modes instead. I wanted to test the aircraft's behaviour on high simulation rates because i use this feature for long range flights. When i set the 4x simulation rate, the flight director started to move left and right so rapidly and the aircraft started to roll left and right to capture it. Why could it be happened? I failed to select heading hold or heading selected? Is it because i didn't Set up the fms completely? But the aircraft's behaviour was pretty normal at normal simulation rate. 

This is a recognized problem when using the increased sim rate on the QW 787.

 

The advice from the developer is to only use increased sim rate on long, straight segments where there are no changes in altitude , speed and heading otherwise its best to resume 1x simrate.

For further advice on the QW787 , its best to look on the Flight1 forum.

Or, use the free Lorby Time Machine.

I have no problems using x4 at cruise level with the QW787. Not quite sure what might be different with heading mode, but LNAV works.

😱😱

This is a must have for me then. I was restricted to PMDG planes only because they had that feature integrated already...
