Measuring top speed is an essential part of tuning your RC car.
It provides clear data on how your modifications impact performance.
Today, I will introduce the device I use for all my speed runs.
CYCPLUS GPS Cycle Computer G1

Although designed for bicycles, it is perfect for RC cars.
Since it uses GPS, you can start measuring just by placing it on the car.
There is no need for complicated wiring or external sensors.
Package Contents and Mounting

For RC car installation, I use the included rubber bands.
The unit can be easily detached from the mount for charging.
Even during high-speed runs, the mount stays secure.
Mounting Examples (DT-04 / Grasshopper)
Here are some examples of how I mount it on different chassis.


Next is the legendary Grasshopper.

Its compact size makes it compatible with almost any RC car.
It weighs only 70g, so it doesn’t affect the car’s handling.
Features and Specifications

Key specifications for RC enthusiasts:
- Waterproof: IPX6 rating (safe from splashes and dust)
- Charging: USB Type-C (convenient for field charging)
- Battery Life: Up to 55 hours of operation
The “Max Speed” memory is exactly what we need for speed testing.
Conclusion
The CYCPLUS G1 offers high GPS accuracy and reliable data for a low price.
It has become an indispensable tool for my RC hobby.
