Requirements

Installing the Turbine Sound Enhancement Mod

  1. Close MSFS 2024. Make sure Microsoft Flight Simulator 2024 is fully exited before installing. If it is running, the Community folder may be locked.
  2. Download the installer (.exe). Open the download link from your Stripe confirmation email and save FWX-EC135-SoundPack-Setup-v1.52.exe to your desktop or downloads folder. You can re-download up to 3 times by entering your email and order number. No ZIP, nothing to extract.
  3. Run the installer. Choose Install when prompted. Double-click FWX-EC135-SoundPack-Setup-v1.52.exe. When the installer opens it offers two options. Pick Install. Windows SmartScreen may ask for confirmation. Click More info → Run anyway (the installer is not code-signed yet, it is safe).
  4. Confirm the Community folder. The installer auto-detects your MSFS 2024 Community folder for MS Store and Steam. If you use a custom location, point it to the correct folder manually.
  5. Read the Package Reorder dialog carefully. From v1.42 onward there is an explicit dialog about package load order. On some Steam installations the FWX package must be placed ABOVE the default EC135 so the new sounds take priority. Check the box to confirm you read it.
  6. Finish the install. Click through the remaining screens. The installer just copies files; no Python or Visual C++ runtime is required, and there are no drivers to set up.
  7. Start MSFS 2024 and load the EC135. Start a free flight with the EC135. Start the engines. The new turbine should be audible immediately.
⚠️ Steam users: Package load order

If the new audio is not audible after installing, the package load order inside MSFS needs adjusting. Inside MSFS go to Content Manager, find fwx-ec135-sound and make sure it is loaded above the stock EC135 package. Restart MSFS.

Installing the FWX Helicopter Rotor Blade Haptic

  1. Connect your haptic device. Any shaker or transducer connected as a standard audio output device on Windows. Make sure it is recognised in Windows Sound settings before installing.
  2. Run the installer. Choose Install when prompted. Double-click FWX-RotorHaptic-Setup-v1.53.exe. No ZIP, nothing to extract. When the installer opens, pick Install. Same SmartScreen confirmation as above.
  3. Pick your installation folder. Default is C:\Program Files\FWX\RotorHapticEngine. Accept or change it.
  4. Start MSFS 2024 with any helicopter. There is nothing else to install and no separate program to open.
  5. Open the FWX Control Center from the toolbar and go to the Haptic tab. Pick your device from the list and press Apply & Save. That is the only setup step - and it is done inside the simulator, in mid-flight if you like.
  6. Fly. The rotor arrives in your seat or through your controls, on every helicopter in MSFS 2024, turbine or piston - not just the EC135. It comes preset for the common types.
✓ Tip: tuning the pulse strength

The Haptic tab of the FWX Control Center has three sliders - volume, bass and pulse strength - plus a test pulse button so you can check it on the ground. Start at the default, then adjust while flying. Changes apply straight away, without a restart.

Troubleshooting

The new audio is not audible after installing.

Package load order. Inside MSFS → Content Manager → make sure fwx-ec135-sound is loaded above the stock EC135 package. Restart MSFS. This is the #1 issue on Steam installations.

The Haptic tab shows no device.

Windows does not see your transducer as an audio output device. Open Windows Sound settings → make sure the device is listed and set as a default or secondary output. Then close and reopen the FWX Control Center panel; the device appears in the list.

SmartScreen blocks the installer.

Expected. We are not code-signed yet (code signing is €250/year, planned for a future release). Click More info → Run anyway. The installer is safe, it only writes to your Community folder and Program Files.

I bought it, where is my download?

Check your spam folder for the Stripe email with the download link. If it is not there, email support@fwx-simaviation.com with your order number and we'll resend it within a few hours.

Uninstall

Run the same installer (.exe) you used to install. Each FWX installer doubles as its own uninstaller. When it opens, choose Uninstall instead of Install.

The uninstall is straightforward: just run the installer file you already have. There is no ZIP to manage, no Windows registry to clean by hand, and no Control Panel step.
