Refined Performance in a Compact Unit

The O.S. Engine OSMG2082 21TM with Revo Manifold delivers a measured boost in power while staying compact enough for popular chassis. It is a practical upgrade for those wanting smoother midrange and top-end control.

Mounting and Starter Compatibility

The 21TM shares mounting and clutch dimensions with several Traxxas platforms, so fitting is typically straightforward. Manifold options cater for both pull-start and EZ-StartTM systems to suit workshop preferences.

Tuning Detail with 3-Needle Carburetor

With a 3-needle carburetor, the engine offers nuanced control of fuel and air for precise running. The included LC3 glow plug helps ensure consistent ignition and easier starting in a range of conditions.

The 21TM suits tuners and racers who want a compact, easy-to-fit engine with reliable ignition and detailed tuning capability.

What should I check before first run?

Confirm mount bolts and clutch alignment, fit the supplied LC3 glow plug, and use a conservative needle setting for the initial break-in runs to protect the engine.

Is the OSMG2082 suitable for 1/8 scale cars?

The 21TM is a smaller displacement engine than typical 1/8 scale powerplants; it is better matched to 1/10 and smaller platforms where its size and weight are advantageous.

How do I know when to change the glow plug?

Replace the LC3 glow plug if starts become sluggish, idling is unstable, or if fuel consumption increases noticeably. Regular checks during race weekends are recommended.

Are there common upgrades to pair with this engine?

Upgrades often include higher-flow air filters, tuned exhaust manifolds, and lightweight clutch parts to get the most from the engine while keeping reliability in mind.
