When I open my helicopter project in the Aircraft Editor (which has
engine_type = 3 in the engines.cfg), only piston and turboprop elements can be
selected in the Engines type dropdown. When saving the aircraft in the editor,
it ends up setting engine_type = 5 in the cfg file. Is this expected behavior,
why has the heli-turbine type disappeared?
Hello @aenbacka , I just tested it and the Helo-
turbine is in the list. The value is set to 3 when we select and save the
config. 
Can you send us your
project to investigate ? [http://devsupport.flightsimulator.com/t/how-to-report-a-bug-or-

crash/77) Regards, Boris
I also now tried to create a new aircraft project, as well as open the sample
Cabri G2 project; also in these cases I have only Piston and turboprop in the
dropdown list.
Hi @aenbacka , I was able to reproduce this using
the category “Helicopter” instead of Aircraft. Indeed, this is an issue and
this will be reviewed. Thank you for pointing this out 
Regards, Boris
Hello, Any updates on the timetable for this fix. Currently it makes
development somewhat a challenge when the correct type cannot be used. Is the
only alternative to edit the files in a texteditor and compile with
fspackagetool?
Hello @aenbacka , No news on this subject for now. I will keep you updated.
Yes, the only workarround at this moment is to edit the cfg and to use
fspackagetool.exe to build your package. Regards, Boris
