Dave Hadfield: “The narrow landing gear is not the problem that you read about in some books… it really does have good manners on the ground.”
This topic has come up numerous times on here. As far as I can tell, it’s a combination of: big, heavy, high powered tail draggers actually are quite difficult; Flight Simulator has some issues in the realism department here or outright bugs including ground to air transition and crosswind handling; and some controllers aren’t helping either.
I’m hopeful that this topic gets an extensive revisit by Asobo and third party developers with the Reno Air Racing update as it features the P-51 and T-6. It would be a shame if they released those iconic birds with such bad ground handling that most players can’t even get them off the ground, but also a shame if they strip them down to arcade level as the “fix”.
