I was flying the Ranger (the stock one provided in the craft files) but every time I fly it to space (I fly up at about a 30 degree angle), one of the airintakes ends up getting more air than the other side, and the other engine just stops, then for some weird reason, I cannot turn off the other engine that is still running until a couple of seconds after it happens. Also, when I fly the Lander (the stock one provided in craft files), It always ends up tipping over and tumbling when I am on full throttle, This also happens with RCS off at about half thrust. Finally, the Endurance engines. The endurance engines could use a bit more power, especially considering people will put landers and rangers on it. When I was flying it at full throttle with just two landers and one ranger on it, my orbit around kerbin was only changing by about 0.1m/s
