you know what this is its a monster truck a crd monster truck well its where the chassis comes from. note before reading more the suspension isn't that flexable one because for some reason when the rotators phisical form is changed it just stops it don't work no more. two to many small parts makes it hard add something and if you wanna try and fix it so it can flex then go ahead i don't mind if you re-upload it. also this to me is a low detail version to me but I don't know when but I will start a high detail with maybe to many parts idk. last thing if you want to make a body for this then go ahead it would be cool to have a veriety of bodys and for any one that watches the monster jam competions the max-d chassis if you want i can make but it may slow down the high detail version.
