Please see my above comment. The devs will monitor the aircraft and its situation, making any necessary changes from there once a sufficient data sample is present.
The GR.1 has its correct engines and performance for those engines. Its not incorrect for it to have the 101.
Its using the offical manual speeds.
Not sure what issue you are referring too here, but I cant find a submitted report for it.
Invisible fuel tank bug on console has been fixed, its just pending deployment on the respective platforms.
No reports have been submitted yet on the FM. We will review and pass them as and when they come in.
