This is a Single User arcade-style racing platform for, dekstop or notebook, set on the official HFCC RC circuit.
The platform focuses on driving, training, and getting familiar with the track layout.
It is designed for free driving, improving consistency, comparing lap times, and most of all: having fun.
In Short
In this Single User game you can run race simulations of up to 20 laps.
All lap times are shown in an overview on the left side of the screen.
The game calculates your total race time and stores your best total race time
(BTOT) locally in your browser.
When telemetry is enabled, the game will show the message
"Recording stopped. Save (Y/N)?" in the top-left corner when you stop driving.
This allows you to save a race session to your computer and replay it later using
the L (Load) function.
The on-screen dashboard provides additional information such as lap data,
speed, averages, and other driving metrics.
Using a RC Dongle and transmitter
You can use your regular RC transmitter together with a standard receiver.
The RC dongle is connected to the receiver in the same ports normally used for the steering (th) servo('s) and or ESC. The dongle receives the electrical signals (from the small connectors) that would normally go to the servos and converts them into digital data.
The dongle is then connected to a desktop or notebook computer using a USB-C cable.
Once your transmitter is switched on, the calibration software will guide you through the setup process,
allowing the game to correctly interpret the steering and throttle signals for use on the track. The settings on your transmitter can be adjust the amout of steer etc.

What not
- Keyboard steering is not support in this version
- Mobile phones and tablets are not supported.
- It 0.91 there is no support fort calibrating and or playing with a gamepad.
- Safari is currently not supported
- There is no Multi user mode
- Car setup cannot be adjusted
First Time Setup
- Open the start screen or main menu.
- Select Calibrate Controller.
- Follow the on-screen calibration instructions.
- The calibration data is stored locally in your browser.
During calibration, keep the steering and throttle completely still
in the indicated position when you press Enter.
The current input position will be stored as the neutral reference.
Calibration can only be started from the menu.
During a race, recalibration via a key is not possible.
Note: With some transmitters, you may need to use
REV (reverse) on steering or throttle for correct behavior.
You can also fine-tune your transmitter just like a real RC car,
using settings such as D/R (Dual Rate), expo, and endpoints.

Controller (RC Transmitter)
The game is designed to work with standard RC transmitters and receivers.
The steering and throttle outputs from the receiver are connected to the USB dongle,
just like they would normally be connected to a servo or ESC.
The dongle converts the RC control signals into inputs that can be used by the game.
HFCC dongles are compatible with standard RC transmitters and receivers for RC cars.
- Steering – Analog steering input
- Throttle – Analog throttle input
- Brake – Analog brake input (if supported)
Race Start
- A countdown with three sound signals is played before the start.
- Throttle input is disabled until the third countdown signal.
- After the countdown, a random start signal is played within 2 seconds.
False Start
- Applying throttle before the start signal triggers a False Start.
- Moving the car between the third countdown signal and the start signal is also detected as a False Start.
- A warning message is shown on screen.
- The engine sound is muted immediately.
- Press Enter to restart the start procedure.
Race Flow (After Start)
- The race becomes active with lap and sector timing.
- After the final lap, a finish phase starts with automatic deceleration.
- A game over screen is shown with the race results.
ST (Start position-to-Finish-line Time)
-
Reaction time at the start is an important factor for fast racers.
The ST value, shown separately above Lap 1, allows you to see
your reaction time and the time it takes to reach the start/finish line.
ST is part of the Total Race Time.
Telemetry
-
During each race, telemetry data is automatically recorded in your browser.
When you stop driving, you can choose to save this data and replay it later.
- Automatic telemetry recording during races
- Replay and analysis of driving sessions
- Tracking of speed, steering, throttle, and brake inputs
Audio
- Engine sound
- Countdown sound
- Start signal sound
- Finish sound
- False start warning sound
Data Storage & Privacy
The game runs entirely in your browser.
All data is stored locally on your computer in the browser(1), including controller calibration,
zoom settings and best total race times (BTOT).
Local data is stored using your browser’s built-in local storage feature.
This allows your settings, telemetry data, and best times to be remembered between sessions.
No data is sent to or stored on any of our servers.
The game does not collect, upload, or track any personal or gameplay data.
HUD (On-Screen Information)
- Lap counter – Current lap number and total number of laps
- Sector timing – Individual sector times for each lap
- Speed display – Current vehicle speed
- AVG speed – Average speed per completed lap
- TOP speed – Highest speed reached during the session
- ST – Start-to-Finish time (Lap 0, included in the total race time)
Laps, Sectors & Validation
- Each lap is divided into multiple sectors using checkpoints
- All checkpoints must be passed for a lap to be considered valid

Questions & Answers
Why does the track use a 2D helicopter view?
The platform is designed as a training tool.
A top-down helicopter view makes the true layout of the track clearly visible
and shows exactly how the car moves through corners and transitions from one
corner to the next.
This view allows you to immediately see the consequences of your actions,
especially when reviewing telemetry data.
From a driver’s-eye or standing position, the track is always seen at an angle,
which visually distorts corner shapes and distances.
Even if the brain corrects for this distortion, the result is a less precise
understanding of the racing line.
When you learn a circuit from a helicopter view first, the brain can easily
translate that knowledge back into a 3D driving perspective.
This makes the helicopter view the most effective and neutral reference for
training, analysis, and consistent lap improvement.
- Why is a gamepad not supported yet?
-
A gamepad uses a fundamentally different way of controlling input.
Gamepads have very short joystick travel, which makes them far too direct.
A small thumb movement already results in a very large steering, throttle,
or brake input. Even a minor correction can cause an extreme steering action.
We are investigating whether limited gamepad support could be added in a
future version purely for fun or accessibility. However, the main goal of
the platform is to train fine motor control using RC transmitters.
- Why is there no keyboard support?
-
Keyboard input is digital: a key is either on or off.
You cannot press a key “a little bit”.
When you press a steering key, it instantly applies 100% steering input.
To compensate, you would have to rapidly tap keys to guide the car through
corners. At the simulated speeds in RCCT, this results in either full throttle
or full braking, making the car physically unstable and unrealistic.
This breaks the driving physics and makes proper control impossible.
