Pff, damn weather ....
Nevertheless I couldn't resist
Took her out for a spin with factor thr at 0.466 bit she still dropped but now very slow
So lowered the factor even more to about 0.420 and it holded alt very well
I still quite impressed how it flies in strong wind and holds it position.
For the record, I'm using R37
Here the graph from the logging. (It was very windy!)
