I just have the old G2 sim. You can probably pick one up cheap. I think its fine for practicing and trying stuff out. The "wind" isn't very realistic. Actually, if you type in a good cross wind, but with no gusts, it acts about right. But the gusts are rediculous. Its like flying in a tornado.
I always had trike gear on my Stiks. And if I ever get another one, it will have trike gear. I just love the way they land with trike gear, nose high. We would do touch and goes and never touch the nose gear to the ground.
I don't understand the big fuss about tail draggers. They aren't that big of a deal. I say that, but I've been flying for nearly 30 years. But I don't remember having that much trouble with them, ever. I'll say this. Some tail draggers like you to 3 point them and some land better on the mains. I don't know why. I don't know what the difference is. They are just different that way. My Cap232 lands great on the mains, but don't try to 3 point it. My Chipmunk loves to 3 point.
