If you experience the "prop pitch bug" in the 109E4

[Insuber]

The bug (or wrong management by the pilots?) in my case consists in the pitch going down low at coarse 8:30-1500 rpm after take off, and keeping there no matter what you do with speed and throttle. If one switches to manual and play a little with the pitch, getting rpm around 2300, and then revert to auto, it works again, but after some 20-30 seconds of hesitation. I don't have identified yet a pattern for the "wrong" behavior.

Cheers.
