I'm sorry if I re-asking this question but I can't find the exact same problem, that I have.
I just started to play KSP some days ago. Right now I unlocked the "Avilation" tech node, so I can build some simple airplanes. My planes are flyable, and controllable quite good, everything working right except the landing gears.
At this point i can work with two type of landing gears: LY-01 fixed landing gear and LY-05 steerable landing gear. If I using LY-01 (It is a nightmare to place this correctly) my plane starts permanently "jumping" like a lowrider from Sanandreas, and its not just annoying but don't get me recover my vessel since its leave the surface before i can press the recovery button. (<-May be some collision problem?) If i use a pair of LY-05 with disable steering and one steerable, my plane stops the "lowrider effect ", but an other problem come up. Its never can stop exactly. I know LY-05 has no brakes but I think - if i shut down the engines - its simple need to stop itself after a while, but no. My plane slow down to 5-8 m/s and after that its never stop exactly, but stop loosing impulse and go forward (or backward) infinitely. Also if I use parachutes to slow down my planes first its work but after its slow down the chutes get cut automaticly , and my plane re-accelerat to 5-8 m/s Its means two thing: 1.) I'm a genius who invented the perpetuum mobile. and 2.) I can not use my planes, since if I go to EVA, my airplane leave my kerbals and they need to run after like a comic book characters... Please help me, my Kerbals are sad.
KSP version: 1.4.4 (Linux build)
