The MiG-15 is the "quirkiest" airplane I've ever flown. Here are a few that I recall from just 1 flight in it:
-The only flight hyds are for the ailerons. When the Russians built it, they realized they needed a way to balance the heavy elevator forces, so rather than aerodynamically balance it with an offset hinge or elevator horns, they installed a big balance weight in the tail. Flying it, when you start to pull more than 3g, the stick force gets really light. Keep pulling, and the longitudinal control forces abruptly reverse, meaning if you let go, the stick snaps all the way aft and bad things happen.
-It has a giant centrifugal flow engine which generates enough gyroscopic precession that it can actually roll the airplane upright if you do a loop and don't feed in coordinated aileron and rudder over the top.
-No fuel gauge, except for the feed tank. The feed tank lasts about 10 minutes. If you wait for the fuel gauge to come off the peg, you'll flame out at the initial.
-Really bad Dutch roll, like +/- 45 degrees of bank in the landing configuration. Relatively easy to counter, but scary if it's a turbulent or gusty day.
-No aileron effectiveness below 130 KIAS, IIRC. You touch down below that.
