Mad Spirit TNS-B Brief for Trail and Track

The Tamiya 43529 Mad Spirit TNS-B is a ready-to-run nitro buggy designed to balance durability and tunability. It suits enthusiasts who want a dependable 4WD platform that responds well to setup changes.

FS-12FD Engine Features

The 2.1cc FS-12FD sits at the centre of this buggy, complete with a drum-type carburetor and a recoil starter for quick ignition. The unit is straightforward to maintain and tune for different running conditions.

Double-Deck Chassis Strength

This model uses the TNS-B shaft-driven 4WD layout in a double-deck frame, pairing a 2.5mm aluminium lower plate with a resin upper deck to deliver a stiff, predictable chassis feel.

Handling and Suspension Geometry

Independent double wishbone suspension coupled with oil-filled dampers keeps the wheels planted. Newly designed long-span arms, reinforced shock towers, and solid hubs improve stability when landing jumps or cornering hard.

Brake, Tank and Practical Details

The large diameter brake disc provides reliable deceleration control, while the 65cc fuel tank and choke pump provide about five minutes of run time per fill depending on use and tune.

Whether you tweak setup for track days or run it on local trails, the Tamiya 43529 Mad Spirit TNS-B gives a reliable, tunable 1/10 nitro experience.
