Strange new speed "problem"
I have used this aircraft for a long time and always found setting prop and throttle lever around +/- 75% would give a steady cruise of about 230/240 knots. In the last three flights my speed goes through the roof even with very high vertical speeds set. I have to set the throttle back to less than 50% in the cruise!
Very odd. It is the same aircraft I have always used with no updates I am aware of.
