@Jonathan, I installed the DHC-6 through the aircraft center in the qtlauncher a few days ago. I show three variants (wheel, float and ski). It doesn't say YASim or JSBSim. It is not giving me any prompt to update. Do you know what I should be seeing, a YASim and JSBSim variant, each with the three undercarriage choices or is it now only suppose to show the JSBSIm version?
Edit:
I noticed you it was committed 5 hours ago, maybe it takes awhile to show up in the launcher?
