Hello, I’m trying to build a vehicle based off crazy carts by razor, but it either has a seizure if i make the wheels small or barely drives at all.
The reason i used a-chassis was to save time
i don’t feel like scripting an entirely new script, but i’m willing to make some changes to a-chassis scripts.
