PyroSA Posted March 24, 2023 Share Posted March 24, 2023 KSP Version: 0.1.1.0.21272 Operating System and version: Windows 11 CPU and GPU models: AMD 5600, GTX3060 Description of the bug. Expected Behavior Wheels should roll only under power, if anything should decelerate when turning Observed Behavior Wheels, even unpowered ones accelerate the vehicle. Steps to Replicate. Build a small car with the largest wheels. Max speed should be 14m/s. Launch it on the runway. Vehicle might start rolling right as it launches, and even accelerate if it's off balance. A few swerves can cause it to rapidly accelerate - it might turns against the direction you input. Fixes / Workarounds Stick to flying A list of ALL mods. If the list is long, please consider using a spoiler window. I've encountered similar before I had mods installed Other Notes I've encountered this before with aircraft wheels as well. Seems related to suspension being compressed at an angle. Suspect it might be related to wheels being clamped to terrain, but and suspension pushing the wheel through the terrain. Every time it adds a little momentum to the vehicle. Video example: Ghost Acceleration Note, SAS is off to rule that out. Link to comment Share on other sites More sharing options...
sir_frost Posted March 26, 2023 Share Posted March 26, 2023 this is a legacy bug from ksp 1 the largest wheels use tank steering therefore they get power to their motors when turning usually the effect of the motors go down with speed. but the turning force on the wheels do not follow the speed curve. by quickly tapping A and D keys while W key is engages we can reach speeds up to 80 m/s (in my personal testing) the expected behavior would be that the largest wheels would turn by selective breaking instead or that the maximum output of the wheels would follow the speed curve.
