I flew a hurricane and a La-5 yesterday. I was able to taxi but getting properly aligned on the runway was still near to impossible from within the cockpit.

Problem 2 is still unsolved. I'm pretty sure you can set waypoints but I was unable to so far.

Problem 3 arose when I noticed that unless I make constant adjustments, my plane doesn't fly straight in any manner. Although a plane supposed to be trimmed before taking off, it still refues to fly in any manner of a straight line when I leveled out and released my stick.
