is in fact and this is difficult to find these videos, but the fact remains that it is not normal that simple grass can completely stop the taxiing of an S-25 the wheels are too big.
other planes could also taxi easily on the grass but not for the purpose of taking off just simply taxiing.
What if we had to analyze dynamic behavior on other types of terrain? ice or mud?
I wish DCS would just make him walk on the grass with a little friction but see a plane that stops completely on the grass and ridicule the wheel and it's not realistic.
