I'm not calling this a 'bug' for certain. For all I know this is how it's supposed to work.
I'm sitting in an FM2 after starting the engine and letting it run to idle, then shutting it off.
The RPM gauge still reads 2000, after shutting down the engine. It only seems to happen while on a CV. I've tried 5 different planes and the results
were the same.
I thought that it may be because the CV was moving, but the gauge read 0 before starting the engine.
This was offline, so I don't know if it's the same online.
