The .18 TM is the hassle-free way to pump up the performance in your T-Maxx or Revo monster machine... because you don't have to modify your model to make it fit! Just drop it in — and you'll instantly enjoy more race-winning speed, as well as more power for backyard bashing!
Lighter and smaller than any .21-size engine, yet the .18 TM outperforms them where it counts — on the track and on tough terrain.
The oversized head is a new 2-piece design that simplifies maintenance.
Traxxas' clutch assembly bolts right on the .18 TM with no modification required.

The manifold on the .18 TM is a direct fit into the T-Maxx; it also adapts perfectly to Traxxas E-Z Start™ Electric Starting System or pull-start systems with no modifications. |
Fins on the 3-needle, slide-valve 11K carb work to cool fuel temperature. The idle screw is positioned down inside to prevent breaking off during rugged off-road action. |
Oversize fins on the newly designed crankcase help to keep the engine cooler. |
