That's a different question.
One question is if the plane should face the wind. The answer is yes.
The other question is... how many speed of wind is needed to face the wind in a grass field?
Well, obviously the speed of wind needed will be high, since plane weights and it's wheels have friction, plane will not rotate except in case of a very strong wind.
This weekend I'll fly a real taildragger again but from a grass field. If there's some wind I'll do the test to see what happens
Anyway, most of the things we are discussing in this post will be adressed, since Luthier told that the taxiing behaviour will be corrected (I hope, introducing propwash and some more friction to the ground when static).
