O.S. Engine 12TG-P Off-Road Favourite 1/10 Nitro Engine  [OSMG1985]

O.S. Engine 12TG-P: Tunable nitro for 1/10 cars

The O.S. Engine 12TG-P gives hobbyists a straightforward nitro option that is both economical and adaptable. It is easy to break in and modest on fuel, so you can spend more time driving and less time fussing with engines.

Practical fuel economy and usable rev range

With the ability to run around 14 minutes per tank in many setups, the 12TG keeps session length high and running costs down. The practical RPM window of 5,000 to 30,000 rpm makes it a flexible choice for varied terrain and driving approaches.

Carbs and tuning for different setups

Select between slide-valve or rotary carburettors depending on your vehicle. The slide-valve is a common pick for 1/10 on-road models like HPI Nitro RS4 and R40 to smooth throttle control, while the rotary carb helps off-road models such as the Associated GT2 and Nitro Evader tackle mixed surfaces.

Designed to drop into modern chassis

The pilot shaft design of the 12TG-P simplifies retro-fit installations into current competition-style 1/10 stadium trucks, making engine swaps less invasive.

The O.S. Engine 12TG OSMG1985 is a solid choice for 1/10 scale RC fans who want an engine that is easy to fit, tune and run across both track and trail environments.
