Remote Control Racing Car

SKU E2K-BOW-C-20H

Build a wooden four-wheel-drive buggy, then build the 27 MHz radio remote that drives it. A single motor turns one axle, and a rubber band belt carries the drive across to the other, so all four wheels pull. Red sends it forward, yellow backs it up.

What they'll learn

Four ideas, one car

All of it is visible in the build, from the motor through to the wheels.

Systems thinking

A transmitter sends, a receiver picks it up, and you build both.

Mechanical transmission

A small pinion turns a much bigger gear on the axle.

Mechanical systems

A rubber band carries the drive across to the second axle.

Controlled variables

Push one fixing ring tight, run it again and compare.

What's in the box

Parts for the car, and parts for the remote

  • ~20 laser-cut plywood plates, numbered ① to ⑪
  • 1× DC motor with a white pinion gear
  • 1× large orange gear and 2× white pulleys
  • 1× yellow rubber band, the drive belt
  • 2× steel shafts, 8 cm, with two orange fixing rings
  • 4× treaded wheels
  • 2× 27 MHz two-channel boards, transmitter and receiver
  • 2× button caps, red for forward and yellow for reverse
  • 2× battery boxes with knife brake switches, one per unit
  • 2× wire antennas, one for the car and one for the remote
  • 28× screws in two lengths, 4 mm and 7 mm coarse
  • 1× illustrated English manual, 24 steps

You'll need to supply: 4 × AA batteries, two pairs, because the car and the remote each carry their own battery box. Also a small screwdriver, and a pair of small scissors to trim the supplied cable ties. The manual asks that an adult be present whenever the scissors are used. No glue is needed at any point in the build.

How this build works

See mechanics in motion

Build the model, set it loose, and understand the science by watching it work.

Build

Around twenty plywood plates, one motor, two radio boards and two battery boxes. Twenty-four steps, screwed together in two screw lengths.

Play

Fit four AA cells, close the knife brake on both units and drive it. Red sends it forward, yellow backs it up.

Experiment

The manual asks for a 1 mm gap between each fixing ring and the plate. Clamp them tight instead and the axles drag. Roll the car both ways and compare.

Educator & Procurement Resources

Essential information for classroom integration and school purchasing.

Every kit starts as a box of parts and turns into something kids can actually use. Making that happen means following directions and fixing mistakes along the way. They're tackling real engineering challenges, but to them, it just feels like play.
Product safety
Children's Product Certificate (CPC)
Certified to US children's product safety requirements
Hold the car off the table, press the red button and trace how the power travels: motor, small gear, big orange gear, first axle, rubber-band belt, second axle. Then mark a start line, drive it forward for three seconds and mark where it stops. Push one orange fixing ring tight against the wood, predict what will change, run it again, then put the 1 mm gap back. Finish with the manual's own challenge: make up the rules of a race with your classmates. What it shows: one motor can drive all four wheels through gears and a belt, and how tightly the parts are fitted decides how freely they turn.
Whether you're exploring circuits in a science lab, tackling gears in a makerspace, or learning at home on the living room table, these kits fit right in. One quick tip if you're building a whole class set: build one kit yourself first, so you know where students are likely to need a hand.

Reviews

Nothing here yet — and we'd rather say so

Verified reviews will appear on this page as soon as the first Remote Control Racing Cars are built at home and in classrooms. We don't carry ratings over from other kits in the range, and we don't publish anything that isn't from a verified buyer.

If you've built this one with your class, we'd like to hear how it went — what worked, what didn't, and what you'd change.

Questions, answered

Before you build

With two buttons, and that is the whole set of controls. Red drives it forward, yellow backs it up. There is no steering: the radio link has two channels, one for each direction, so you aim the car by picking it up and pointing it. Worth knowing before you order, because the word racing suggests a track and this is not a car you can steer around one. What you get instead is a clear look at how a motor, a gear pair and a belt move a vehicle.
Yes, and that's half the point. The kit holds two 27 MHz two-channel boards: a transmitter that goes into the wooden remote you assemble, and a receiver that goes inside the car. Each unit gets its own battery box, its own knife brake switch and its own wire antenna. You're building both ends of the radio link, not a car plus a supplied controller. We don't publish a control range for it, because the same module is quoted with two very different figures elsewhere and neither has been measured properly. Pacing it out in your own space is a sensible first test.
It suits grades 3 to 5 and takes about 60 to 75 minutes. Twenty-four steps, two screw lengths, wiring into a receiver board and a gear pair that has to mesh properly, so it is one of the more demanding builds we make and not the one to start with. It is also one of the kits in the range that needs scissors, for trimming the cable ties, and the manual is explicit that a child must not use them without an adult present.
The car is 140 × 100 × 210 mm, and that height is measured to the tip of the antenna, so the body itself sits far lower than the number suggests. It is a hand-sized buggy, not a large model. The remote is 310 mm tall with its antenna up and 45 mm across the body.
4 × AA batteries, and it really is four rather than two: the car and the remote each carry their own battery box, so a single pair will power the remote and leave the car dead. You'll also want a small screwdriver and a pair of small scissors for the cable ties, used with an adult present. No glue is needed at any point in the build.
