Hi all I never posted anything on here before but I have 2 MST and never had a problem out of them but to answer your question I crashed one of them and and couldn't find a MST chassis so I got the turmoil and all of my MST parts fit just find. But you will save your self alot of trouble if you just convert your MST to a brushless one. That I call the MSTe that is much fast and more powerful and a blast to run. Just a thought !!!!
