I think you need to buy a power driver (with a clutch) to put it together, but other than that, no not really. It's uber durable, and after you get used to it, if you really wanted to break down a transmission at the track to change fluid in between rounds, you could.

I cannot describe how little maintance this truck is vs. how much track time you get. We run seven minute qualifiers and ten minute mains plus whatever track time you get in practice. My truck looks brand new after four race days, and the only maintenance I've done is go over it to make sure nothing is going to fall off in between rounds (it never does) and blow it off at the end of the day. I think I deglazed the slipper pad twice, and cleaned the hinge pins once.

It uses all metric hardware, well, mine did till I started building some parts for it...
