As we getting same questions again and again, we need to make clear statement, that we will do our best to make all our hardware compatible with latest MFS 2020 as soon as possible. We already working on it and we should be ready right in time. But we need to be aware, that hardware compatibility with MFS 2020 is not enough. Most important is that aircraft developers updated their aircrafts. Then please make sure, that aircraft you want to use is compatible in first place.
More info and details will come after official release date, most probably at the end of August.
