This Traxxas engine is for modelers who are looking for a higher performance than a .12 size engine in their 1/10 scale kits, like the Nitro Stampede, RC-10GT or GTX. This is the Non-Pull Start Version.

One Assembled Engine without Pull Starter, one Air Cleaner (black rubber with black foam element), one Full Instruction Book and Parts Exploded View, one Traxxas Decal Sheet, and one Installed Glow Plug (standard long--no idle bar)

1/10 scale kit to put it into
5%-20% Glow Fuel

Note: Traxxas engines run much hotter than other engines (O.S., ASP, Thunder Tiger, etc) Because of their running temperature, Traxxas recommends using their Top Fuel (#TRAP5010) and their glow plug (#TRAG3230) to run the engine cooler.
