Joystick & Flight Stick Tester
Test HOTAS, flight sticks, and specialized joysticks. Check multi-axis movement, throttle quadrants, and dozens of discrete buttons.

Normal variance. Your controller is operating flawlessly.
Slight potentiometer wear detected.
Severe drift detected. Repair is highly recommended.
How to Get Started
Just three steps to run a complete controller test and understand your controller's health status.
Connect Controller
Connect your controller to your computer via USB cable or Bluetooth. If the browser doesn't respond, press any button on the controller to activate the connection.
Button Detection
Press each button in the visual interface and confirm the corresponding area lights up on screen. This helps troubleshoot unresponsive or double-clicking buttons.
Sticks & Vibration
Rotate the sticks to check linearity and drift issues; click the vibration test button to feel if the left and right motor feedback is working properly.
What would you like to do next?
Select a diagnostic calibration suite, deadzone analyzer, or high-frequency overclock tool.
Repair & Calibration
Calibrate zero-point offsets or follow step-by-step repair guides.
Game Deadzones
Calculate exact radial vs axial deadzone overlays for Fortnite, Apex, & COD.
Overclock & Circularity
Verify true hardware polling Hz stability and statistical circularity grades.
How do you calibrate a flight stick or HOTAS system?
You calibrate a flight stick or HOTAS by navigating to your operating system's USB game controller settings, selecting the device, and running the calibration wizard. Move all axes, including the throttle and rudders, to their maximum extents to register full range of motion accurately.
Recommended Actions
Start with the Stick Drift Test to check every axis at rest. A centered stick should sit near zero on pitch, roll, and yaw before you calibrate the throttle and hats.
Frequently Asked Questions
Everything you need to know about testing your controller.
Why is my flight stick pulling to one side?
This is often due to improper software calibration or physical sensor misalignment. Re-calibrating in Windows or the manufacturer's software usually fixes it.
How this test works & its limits
- This test reads your controller through the browser's standard Gamepad API — no drivers, no installs, nothing leaves your device.
- Readings depend on connection mode: Bluetooth reports at lower rates than USB. Compare like-for-like (wired vs wired).
- We measure the input reaching the browser — display lag and game-engine queues are outside this test's view.
- A clean reading now does not guarantee no drift in-game: deadzones differ per game, and wear develops over time. Use the Drift Timeline to track yours.
- This is a diagnostic, not a hardware-lab certification. For repair or RMA decisions, confirm with a second run or second tool.
All Gamepad API data stays in your browser. Zero tracking or data collection.
