AH has a TV commercial now? Anyone got a link?
Welcome to Aces High! This is a fun game with a very good community in it. An easy plane to learn to fly in... depends there are a couple planes that can be considered very easy in one category of flight and difficult in another, it all depends on what you want to focus on. What I would find difficult in learning how to fly in this game with the P51D is a couple things. First is one that all single-enging fighter have in this game, and that's engine torque. An easier way to take off and land is with a two-engine light/fighter aircraft, in regards to eliminating the single-engine torque problem. Try the P-38 for some takeoffs and landing on your own, in my opinion it's one of the easiest fighters to land and take off, light or heavy. And speaking of light and heavy and the P51D, that plane in my opinion does not like to be heavy and/or slow and/or low. If I'm flying on the deck and doing a lot of maneuvering, I prefer the P51B, the P51D really likes the altitude and really shines above 15k. If you're just practicing landings and takeoffs and some low altitude maneuvers, I recommend trying a light (25-50% fuel, no ord) P51B or a light P51D is similar enough if you want to stick with it.
The Training Arena in this game is great resource, take advantage of it and the awesome people there to help. They'll repeatedly watch you turn the pristine runway into what looks like the surface of the moon until you get it right, and even let you shoot them down all in the name of making you a better shot.
