Hello Guys, I logged into this forum, because I need help to safely achieve my own ground speed record with stock parts, but there is one problem, which occurs no matter which craft you use. If you finally reach damn high speeds, over 2000ms, You have the problem, that you collide into the terrain. To solve that problem which already occurs at 800 m/s you can put your aerodynamic quality to minimal, then you can achieve speeds over 2000ms easily with sepatrons. But when you start to slow down, you crash into the ground again, but how can you fix that? I already put everything on the lowest settings and put some back to see if it's changing something. What can you do about it? Suggest me Mods or other solutions to fix that. Stratzenblitz75 already posted something about it: https://forum.kerbalspaceprogram.com/index.php?/topic/160697-the-speed-of-ground-a-study-into-how-ksp-terrain-colliders-handle-land-vehicles-with-high-magnitudes-of-velocity/
