    As I live in Perth, the winds are generally very strong.

    I noticed that on a simulator, when setting a strong wind ( 40 kph / 20 knots ), it was challenging to take off using a normal flight mode, however, taking off using idle up or a higher head speed made the take off much easier and cleaner, along with hovering.

    Has anyone tested this characteristic in real life?

      Higher head speed handle higher wind better... well that reads just plain wrong... but in a word yes

      what I'm about to say all depends on disk loading and size of the heli and rotorblades... but it's all relative.

      consider this, for hovering in F3C 1450 in normal conditions and 1490-1500 when it's windier.
      1900-1950 and sometimes 2000 in idleup when doing aeros.

      For more authority on the tail and cyclic and to get crisper stops and additional momentum during very headspeed taxing manouvers during 3D, higher headspeeds are desirable. It's my understanding that it gets to a point though where you are just wasting energy for no major gain. Being no professional on this subject, I'm sure Dargue's or Marco could shed some light.

      Also higher headspeed during crashes means more pieces ;)

      Interesting you mentioned the F3C , as I hovered a Hirobo Freya on Sunday when it was windy, only in normal mode, and it took the wind extremely well.

      Mind you, the local did sell me a longer flybar and heavy paddles, I think that helps.
