R44 SkyLabs XPlane can't wind up the throttle

Hi Folks, I had everything working brilliantly, Xplane11 R44 Puma Pro controls VR all good. Now, using wing sweep to wind up throttle, it gets to 60/70% then drops back. Seems Govner working but even past 80% Gov doesn’t pick up. I thought maybe the slider on the throttle might be faulty but all works fine in calibration. I reloaded R44 - same. Plane all up to date and I understand not to reinstall to fix these things. Any suggestions…? Anything I can delete to reset ? With thanks from the most frustrated guy in Essex :slight_smile: and thank you … A clue - R66 has no glass cockpit working and experiencing the same issue…
