    Spaceplane???

    whenever i construct a spaceplane, it usally likes to pitch up to 90 degrees and stall.
    or, on a good landing one time using the plugin gear, at -4 m/s down, as soon as i disengaged mechjeb the aircraft did a baackflip and crashed.
    could someone tell me what im doing wrong?
    maybe give me a good plane?
    Pm me if you need help in KSP.

    I believe the forward drag on the aircraft is greater than the rearward drag. Naturally, drag forces will flip it over. I\'ve had this problem countless times. It could also be that your center of gravity is not in line with the center of lift.

    My go-to plane would be this: [spoiler][/spoiler]
    It uses Tosh\'s cart plugin for landing gear, which works marvelously. I\'ve never had a problem, and it has a decent range of about ~40km

    Hope I helped.

    Sounds like your plane\'s center of gravity is waay behind the wings. Either move the weight forward, move the wings aft, or both.

    Not yet, that I know of. I usually find it through trial and error.

    I learned by trial and error, and ironically my first success was designed to be a failure. You never know what may work.
