O.S. Engines® 12TG Engines

Features

ROAR-legal for racing and ready to deliver up to 14 minutes of run time per tank!

Easier to install (and retro-fit) than sidewinder engines — and more powerful, too.

Versions available for popular 1/10 scales, including the HPI Racing® Nitro RS4 or R40, Associated RC10GT2 and all DuraTrax Nitro Evader vehicles.

On-road 12D slide-valve carb and off-roaders' 12E rotary carb feature 2-needle tuning for easy set-up and finer-pitched needles for longer-lasting settings.

Exclusive ABL™ (Advanced Bi-metallic Liner) lengthens racing life, but shortens break-in time.

Tornado head offers wider fins for better cooling and the cost savings of standard plug use!

Rear-exhaust design comes to 1/10 scale racing!

It's not just for 1/8 scale anymore. The O.S. 12TG brings the extra power and installation ease of rear-exhaust power plants to American club racing — for a price that makes buying O.S.'s best the racer's most affordable option! Off-road, on-road, indoor, outdoor, recoil or manual start — there's a 12TG for every racer, and more performance and ease for every one.

O.S. fit, finish and quality in every component, from the long-wearing ABL sleeve and knife-edged conrod to the large-diameter crank and easy-to-adjust 2-needle carb.

The O.S. T-1040 Tuned Pipe (LXHGK5) — the perfect power pair-up for all three 12TGs! (Available separately.)
