On ground, when taking off (tried it offline with a Spit 2a with the quick mission where one can take off from an RAF airfield to cross the channel and online in a Tigermoth on a server set up by a friend. Both times the same issue):
One wheel seems to stick deeper in the ground than the other making the wings very unlevel - considerably unlevel. It seems to occur particularly on the right wheel (Tiger Moth and Spit) but cannot exclude that other wheel is concerned too.
I have some doubts about the artificial horizon of the Spit 2a. Not sure if it works as it indicates most of the time a steeply inclined horizon even when I fly considerably level.
Does the ground texture when having gras turned off also this dreadful look for you?
