I have just reinstalled Windows 10 and then MSFS, Orbx Central and then the Tutor T1 but I see neither of the files that you pointed too, and I still have no avionics. The files that you mentioned are still nowhere to be found.
The aircraft flies well, in fact it is rather fun even without the avionics but without them is a big disappointment.
I hope this will be overcome in the future.
Kind regards
Richard
