O.S. MAX-21TM Revo .21 Nitro Engine with 11K-R Carburetor
From
$299.99
The O.S. Max-21TM (Revo) Off-Road Engine W/11K-R Carb 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.
Includes the 11K carb that most 21TM owners end up upgrading to anyway- no need to spend the additional ~$100 later.
