Features
|
- The 21TM adds more power and displacement than the 18TM — and without modification!
|
- Retrofits into the same mounting pattern, and the Traxxas clutch assembly bolts right on.
|
- The special manifolds adapt perfectly to existing pull-start or EZ-Start™ systems.
|
- Reliable, lightweight and easy to operate — and both include a 3-needle carb for more precise tuning and an LC3 glow plug.
