As for tumbling, it’s not really an issue on beginner\int gliders. They are inherently very stable machines. For that matter even a sensibly tuned topless glider at the looser VG settings is also quite resistant to tumbling. The very nature of weight shift flight means that we get a lot of feedback from the air we are flying through. This can have the effect of throwing us around a bit sometimes, but once you stab past this perceived annoyance, you will realise that this is one of our greatest assets as a hangie – We can get a really good idea of what even the smallest pocket of air is doing.

So, short of acros or flying directly into severe mechanical turbulence (lee side of a mountain in strong winds), don’t stress too much about tumbling. By the time you are in a glider that this might be an issue you will have a lot more experience under your belt and will probably be able to explain this concept better than I have attempted to here.
