12TG Engines

OSMG1986

OSMG1989

The ideal engine for getting into nitro!

The 12TG is economical, easy to break in – and makes any vehicle ROAR-legal. The 12TG consistently delivers up to 14 minutes of run time on a single tank of fuel.

Available with or without pull start, and comes with either a slide-valve or rotary carburetor.
Steer 1/10 scale on-roaders to the slide valve carb-equipped 12TG; it's a great drop-in for the HPI Nitro RS4 or R40.
The 12TG with rotary carb will boost performance in off-roaders such as the Associated GT2 and DuraTrax®'s Nitro Evader.
The 12TG-P features a pilot shaft, which allows for a no-mod retro-fit into today’s top-level competition 1/10 scale stadium trucks.

Quality construction features such as an ABL sleeve and easy-to-tune 2-needle carb make the .12 TG a great choice for the beginner!
