Ah... I was not getting that it needed to be postive (which should have been obvious from the name). I tried it with a negative amount with the same result, so I'm off to try the positive variety.thanks

Making progress.With this:[contact_points]point.0=3, 400, 150, -139, 3000, 0, 2.5, 0.0, 0.3, 2.5, 0.60, 0.0, 0.0, 7.0, 0.0, 0.0point.1=3, -800, 150, -139, 3000, 0, 2.5, 0.0, 0.3, 2.5, 0.60, 0.0, 0.0, 7.0, 0.0, 0.0point.2=3, 400, -150, -139, 3000, 0, 2.5, 0.0, 0.3, 2.5, 0.60, 0.0, 0.0, 7.0, 0.0, 0.0point.3=3, -800, -150, -139, 3000, 0, 2.5, 0.0, 0.3, 2.5, 0.60, 0.0, 0.0, 7.0, 0.0, 0.0static_pitch = 0.0static_cg_height = 135.00It now doesn't go into the ground, but will sit momentarily before bouncing up a bit and then rolling to a crash. So, I'm attempting to widen the contact points to see if this helps.Sad that one must use contact points that are so far from the model.

Ok, figured out that I had to super-size the MOIs. Now she won't bounce just jitter a litte.Main thing is that she won't crash immediately so you can easily move from place to place.You guys were right on the money with the static_cg_height... I thought it was the height of the CG above the zero point, but now realize it's really the distance from the CG to the ground.Now when ACES comes out with a rocket air file or warp drive, we'll be set, haha.
