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-v1.49.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-v1.49.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 Haptic Bass Shaker Mod

  1. Connect your haptic device. ButtKicker, bass shaker or any transducer connected as a standard audio output device on Windows. Make sure it is recognized by Windows Sound settings before installing.
  2. Run the Haptic Engine 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. Enable autostart. The installer offers to register the Haptic Engine in exe.xml so it starts with MSFS 2024 automatically. Leave this enabled unless you want to start it manually.
  5. Open the GUI once. After installation, launch "FWX EC135 Haptic - Bass Shaker Mod" from the Start menu. Select your haptic output device from the dropdown. Click Save.
  6. Start MSFS 2024 with any helicopter. The Haptic Engine reads rotor RPM from SimConnect and sends pulse signals to your haptic device. Works with any 4-blade rotor helicopter in MSFS 2024, not just the EC135.
✓ Tip: tuning the pulse strength

The GUI has live sliders for pulse intensity, blade rattle threshold and low-RPM behaviour. Start at default, then adjust while flying. Changes apply in real time 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 Engine shows "No device found".

Windows does not see your haptic transducer as an audio output device. Open Windows Sound settings → make sure the device is listed and set as default or secondary output. Reopen the FWX GUI, it should appear in the dropdown.

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 [email protected] 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.
