And make sure you don't use the HPI stickers that come with it. All 190mm bodies (Hot bodies, Hotworks, HPI, Tamiya, ABC Hobby, Yokomo, Protoform, Speedway Pal, etc...) will fit your TT01. A few suggestions when doing your bodies:

1) Meausre TWICE before you make your holes. Align the wheel arches of the body as much to the center as you can (so that the wheel isn't too far to the front or back of the wheel arches) and draw the holes with a sharpie or pin. (the top layer is a plastic film that you peel off later so it's not on the body).

2) Until you become a body PRO, Cut first, paint second. Reason being, a lot of NOOBS will scrape the paint when cutting (especially the wheel arches). Nobody likes a car that looks like a 3rd grader did it.

3) Use body trimming scissors AND sandpaper. Rough edges not only look horible, they're dangerous. Nobody wants a lexan cut.

4) A lil dab'll do ya. Don't spray on the paint all extra UBER thick. Unless you're going to back the primary color with something (and chances are that your local hobby shop will tell you not to because that's looked down upon in racing and most of the race), you should be able to see through the body if you hold it up to the sun. It won't look like that on your chassis tho.

I could go on, but that should get u thru. Good luck on those bodies.
