I use Linux Mint 17.3 (32-bit) and saiarcot's recent FG 2018.1.1 build. So far it's working very well. (Thank you(!) saiarcot!!)
I have numerous planes downloaded with the QT launcher in the 2017 version. Every one of them works perfectly.
This version lacks the QT launcher, so one must download additional aircraft manually from "http://mirrors.ibiblio.org/flightgear/ftp/Aircraft/". OK, that's easy. I just downloaded the dhc2 (DeHavilland Beaver), long one of my favorite planes.
This thing has been enhanced since I last used it. My gosh and golly, it's beautiful! Wow. Outstanding work!
Just one problem: it won't start. I carefully followed the checklist - several times. Everything seems to work except... it never "fires". Crank and crank. Nothing else happens. After a couple of minutes, the sound of the gyros winds down and the starter switch (by mouse or keyboard "s") no longer works.
Has anyone else used this plane recently? Any idea what's wrong here? I would try to debug it, but I currently have too many other demands on me, so it would be some time before I could get into it.
