Hello Soarscale. My solution to the “sailplanes crash if started from ground” is to give the sailplane a jet engine, but no fuel. See the DG-808S or the Ka6E from MSFS 2020 sailplane
I do not know this method. But, after I found one solution for a problem, I normally do not search for alternative solutions.
I think Alex Marko and his Kinetic Assistant are the best thing that has happened to “Glider, sailplane, soaring” up to now. See Kinetic Assistant - Touching Cloud [OFFICIAL MOD PAGE]
If you like, please look into this program. He uses SimConnect and C# programming language to give the sailplane totally new capabilities. At the “bit shuffling” end of programming the question “how do you make SimConnect communication as realtime as possible” is open. On the “big project” end of programming the visualization of thermals is open. The CumulusX! program of Peter Lürkens does visualize thermals with flying birds. First his program does place thermals at realistic places by itself, give the thermals a “live”, that is thermals creation, getting stronger, later getting weaker again and disappearing. Second he has these soaring birds that circle in the updrafts. I really love these birds!
If you have FSX:Steam - it is real cheap at Steam - you can install the freeware and payware version of CumulusX! to play with the birds yourself. See Peter Lürkens' Flight Simulator Tools
Peter Lürkens has also the WinchX! program that has animation for the winch start of sailplane. This animation is only eye candy. But MSFS 2020 is a lot about eye candy …
Summary: I suggest things that we had in FSX. This is perhaps not “revoltutionary” like simulation one of Elon Musk’s rockets in MSFS 2020. But simulation is about doing the well know stuff in a realistic and pleasant way. WinchX! and CumulusX! are the best starting points for that.
