When i spawn it using a cheat it stays upside down
try finding one somwhere the game spawns them if they aren't upside down there - problem fixed!, i don't take responsibility for cheated bugs(yes i cheat but i don't know what is going wrong unless i have specifics on where or how you spawn them)
Oops! i found a problem with this mod i probbably uploaded a old versoin of the dart so look for the new file called "dart ver 1.1" for the working version(if you downloaded this before you would have noticed it upside down, that was a old problem i fixed by moving the wheels to the wingtips)
