[BUG REPORT] LS8-18 needs "modern_fm_only =1" in flight_model.cfg

It seems the LS8-18 in SU11 is highly unstable (unflyable?) for the few people
that have “GENERAL OPTIONS” “FLIGHT MODEL” “LEGACY” in their MSFS settings.
This seems pretty clear from feedback on the MSFS Gliders Facebook page, but
I’ve not actually tried it. FYI the “modern_fm_only” entry is missing from the

apologies - I’ve submitted bug reports in the past but I fished around and
couldn’t for the life of me remember where that correct reporting website was.
Thanks for passing it on.
