Flight sim · stick, throttle, pedals

HOTAS Tester

Reads your flight stick, throttle and rudder pedals at once and checks every axis, the hat switch and every button.

Plug in your stick, throttle or pedals and move each one — browsers only show a device to a page once it has been used.

Nothing plugged in yet?

Connect each device by USB, open this page in Chrome, Edge or Firefox, then move a stick or press a button on each one. Windows can also list them under “Set up USB game controllers” if a device does not appear.

Words on this page
Axis

One direction of stick movement, reported from -1 to 1. Each stick has two: left/right and up/down.

Deadzone

A small area around the stick centre that the game ignores, so a resting stick does not move the camera. Too small and drift leaks through; too large and slow aiming disappears.

Quick answers before you test

Why does my stick not show up?

Browsers only hand a device to a page after it has been used. Move the stick or press a button with the page open; each device on the desk appears as its own card.

How much deadzone do I need?

As little as hides the rest offset and the jitter. The bench measures both for every centring axis while you let go, and gives the smallest deadzone that covers them.

Is my HOTAS 8-bit or 16-bit?

Move an axis slowly end to end and read its resolution. The browser scales every axis to the same range, but the steps between values give the real count away.

What the result actually measures

A flight desk is several USB devices — the stick, the throttle, the pedals — and the browser lists each one with its axes and buttons but no names for them. The bench names the device from its USB ids, gives each axis a role from where it rests (a stick axis centres, a throttle sits at one end, a hat parks outside the range), then measures it while you fly it about: how far it reaches, where it settles when you let go, how much it wanders at rest, how fine its steps are and whether it jumps. It also traces the stick, lights the hat switch’s eight directions and counts every button press, catching a switch that bounces.

Measurement boundary: The browser sees the axes after the device’s own firmware and driver: software curves or deadzones set in the maker’s app are already applied, and a driver that smooths the signal hides its true resolution, in which case the bench says “at least”. Browsers list only as many axes and buttons per device as they support, so a few very large throttles show fewer buttons here than in the maker’s software. Force feedback is not tested.

How to interpret the output

Reach

How far an axis travels. A centring axis should reach both ends; a throttle or pedal should travel end to end. Under 95% means part of the range is lost — recalibrate.

Rest

Where a stick axis settles when you let go. A few tenths of a percent is normal; several percent off centre means the aircraft drifts unless a deadzone hides it.

Jitter

How much an axis wanders while untouched. Hall-effect sensors barely move; a worn potentiometer can wander by a percent or more, which a game reads as a twitchy aircraft.

Resolution

How many steps an axis has, shown in bits. 10 bits is 1,024 steps, 16 bits is 65,536; more steps mean finer control near the centre.

Spikes and bounce

A value that jumps and comes straight back is a dirty or worn sensor. A button that registers twice in a few milliseconds is a worn switch.

Troubleshooting unexpected results

A device appears as two, or not at all

Some throttles and HOTAS bases enumerate as separate devices for the base and the grip; that is normal. If one is missing, check Windows “Set up USB game controllers” and try another USB port, ideally not a hub.

The throttle is listed as an axis that rests in the middle

Some throttles have a centre detent or report a split range. The bench names the axis from where it rests; the travel and reach it measures are still right.

An axis jitters

Clean or replace the potentiometer if the maker supports it, or set a deadzone of the size the bench suggests in the game or the maker’s software. Hall-effect upgrades remove jitter for good.

Fewer buttons than the device has

Browsers cap the axes and buttons they list for one device. The maker’s software can test the rest, or map extra buttons onto a second, virtual device.

Frequently asked questions

How do I test my HOTAS on PC?

Open this page in Chrome, Edge or Firefox, move your stick, throttle and pedals so each appears, then move every axis end to end, push the hat and press every button. Each device gets its own report.

Can I test a Thrustmaster T.Flight HOTAS online?

Yes. The bench reads it like any other flight device: the stick axes, the twist, the throttle on its base and the rocker, the hat and every button, and names it from its USB ids.

How do I check my flight stick for drift?

Move the stick around, then let go and keep your hands off for a second. The rest value of each axis is how far it settles from centre; the bench flags anything over 3% and suggests a deadzone.

Do rudder pedals work in a browser test?

Yes. Pedals are their own USB device; the bench reads the rudder axis and both toe brakes and checks that each travels end to end.

Why does Windows calibration help?

Calibration tells Windows the real ends and centre of each axis. If an axis reaches only part of its range here, recalibrating in “Set up USB game controllers” or the maker’s software usually restores it.
