Tamiya 43508 TNX Monster Truck 3.0 Engine RTR - Ready 1/8 Nitro Monster  [43508]

TNX introduction for rough-surface driving

For trail and track sessions the Tamiya 43508 TNX Monster Truck with a 3.0 engine is a strong contender. This 1/8 scale RTR delivers the durability and mechanical simplicity that many hobbyists prefer for serious off-road use.

Powertrain and starting gear

The core of the TNX is its .18 cu in (3.0cc) engine fitted with a dual needle slide valve carb and a race-inspired crankshaft for stable throttle control. The package includes a glow plug heater and electric starter so you can get the engine running without complex setup.

Sturdy chassis and four-wheel drive

The TGM-03 aluminium chassis provides a rigid platform while the hardened steel shaft feeding the 4WD system keeps power delivery reliable under load. The layout is designed to cope with jumps and rocky sections.

Handling and suspension tuning

With eight oil-filled dampers and a double wishbone arrangement, the TNX soaks up rough terrain and big landings. Adjustable camber and steering tie rods make it straightforward to dial in handling for different surfaces.

Appearance and finishing touches

The extended cab body comes with full graphics and decals for a finished look, paired with chrome-look wheels and V-tread tyres to maintain classic monster truck styling on and off the track.

The TNX balances a traditional nitro setup with robust hardware, making it a practical choice for hobbyists who want a tunable, serviceable monster truck that handles varied terrain.
