I thought you could choose warm engines?
Also these aircraft are hard to turn because they are tail draggers they have poor ground handling. Update they are reworking ground physics.
AA does work but only for close objects kind of pathetic for a flight sim
, but they are going to implement new aa software.
Ground colours are a tough subject at first I preferred the previous ones like you but now I am waiting for the dynamic weather to be installed before I jump to conclusions as I reckon that's why they made them a bit lighter.
