3Racing KIT-F109 1/10 F1 RC Kit - Tunable Circuit Racer  [KIT-F109]

Overview of the 3Racing KIT-F109 for circuit tuning

The 3Racing KIT-F109 is a 1/10 scale Formula 1 kit aimed at enthusiasts who like to dial in setup and balance. Its combination of a precision-cut chassis and focused component layout lets you tune handling for different track surfaces and driving styles.

Chassis integrity and front end control

The main FRP chassis at 2.5mm thickness and the 2.0mm upper deck form a rigid platform that resists flex while keeping mass low. The front king pin coil spring arrangement allows predictable independent movement, improving turn-in and steering feedback on smooth circuits.

Power delivery and steering architecture

Featuring a direct drive 2WD transmission, the KIT-F109 offers an efficient drivetrain with minimal complexity. The aluminum ball differential and lightweight differential joint help maintain even torque distribution, while the longitudinal servo and isometric steering geometry keep the steering crisp and communicative.

Scale appearance and aero parts

The lexan polycarbonate body reproduces Formula 1 proportions and works with front and rear wings to shape airflow. Paired foam tyres and rims provide the intended balance of grip and slide for track-style driving.

The 3Racing KIT-F109 rewards methodical builders who enjoy refining suspension and drivetrain settings to suit different surfaces and driving preferences.
