O.S. ENGINES 0.21ci TM Nitro Engine suit REVO 3.3 - OSM12241
Overview
This is the O.S. Max .21 TM Engine with the Revo Manifold (also fits Traxxas Slayer). This engine will be a direct drop in for the Traxxas 2.5 and 3.3 Revo or the Slayer Pro, but requires the OS 23818430 Ball Link. The .21 TM will adapt directly to the Traxxas EZ start or pull start systems. The O.S. .21 TM engine is for serious racers and backyard bashers alike that are ready for some major power.
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 pullstart or EZStart™ systems.
- Reliable, lightweight and easy to operate – and both include a 3needle carb for more precise tuning and an LC3 glow plug.
