Mini 4WD Setup for High-Speed Tracks

A fast, open layout with long straights rewards a completely different setup from a technical one, and the changes go beyond simply fitting a faster motor.

Gear for top speed

A lower ratio, or a larger wheel diameter, lets the car actually reach speed on the straights. Acceleration matters less when there are fewer corners to exit.

Reduce drag everywhere

Harder, low-friction tyres, free-spinning rollers and a clean drivetrain. At high speed, small drag losses compound over the length of a straight.

Stability becomes critical

A car at top speed hits walls harder and lands from jumps further along. Stiffer roller setup and adequate damping are what stop a fast car becoming a spectacular one.

Manage motor heat

Long runs at full output cook motors and drain cells. Allow cooling time between heats and expect performance to change as a motor warms.
