NEW · MAY 2026 Sound v1.49 + Haptic v1.53 + Bundle v1.49

The turbine spool-up is now interruptible by the starter switch at any moment, matching real EC135 behaviour. Engine 1 and Engine 2 are now fully independent for asymmetric start, shutdown and single-engine taxi. New installer with editable Community-folder path picker and clean Apps and Features integration.

FWX EC135 Enhancement Mod: Sound

v1.49

Turbine Sound Enhancement Mod Current · NEW
May 2026

New

  • Interruptible startup sequence. The turbine spool-up can now be aborted at any moment by switching the starter off, matching real EC135 behaviour. No more committed startup once you flip the switch.
  • Fully independent dual engines. Engine 1 and Engine 2 are now completely separated. Asymmetric start, asymmetric shutdown, single-engine taxi: each engine plays its own sound layer.

Installer

  • New installer with editable Community-folder path picker and improved auto-detection.
  • Clean Apps and Features integration for proper Windows uninstall.

v1.46

Turbine Sound Enhancement Mod
April 2026

Fixed

  • Turbine startup sound now plays reliably from cold start. Under certain audio configurations the FWX startup sound in v1.44 could fail to engage, causing MSFS to fall back to the default sound.
  • AI helicopters (AI Traffic) now correctly receive the FWX sounds.

Improved

  • Significantly leaner installation (278 MB instead of 433 MB) and faster installer.

v1.44

Turbine Sound Enhancement Mod
April 2026

New

  • Installer now shows an explicit Package Reorder dialog. On some Steam installations the FWX package has to be loaded above the stock EC135 package, and the dialog now explains this step so it can't be missed.
  • Updated product description and requirements mention the load-order note up front.

Fixes

  • Addressed the load-order case reported by some Steam users where the FWX audio was not audible after installation.

v1.41

Turbine Sound Enhancement Mod
March 2026

New

  • Full cockpit and exterior turbine audio for the EC135 in MSFS 2024.
  • 13 active engine WAVs, 20 non-engine WAVs, custom startup sequence.
  • Tuned pitch variation for a smoother, more realistic turbine response under torque changes.
  • ButtKicker-safe, no internal cockpit bass rumble.
FWX EC135 Haptic - Bass Shaker Mod

v1.53

Haptic Engine Current · NEW
May 2026

Installer

  • New installer with editable Community-folder path picker and improved auto-detection.
  • Clean Apps and Features integration for proper Windows uninstall.

Unchanged

  • Sound and impulse characteristics identical to v1.52. This release only refines the install experience.

v1.52

Haptic Engine
April 2026

Maintenance

  • Maintenance release. Minor internal adjustment, no functional changes compared to v1.51.

v1.51

Haptic Engine
April 2026

New

  • Auto-close: the Haptic Engine now exits automatically when MSFS 2024 is closed. No more background processes after you quit the sim.
  • Stability and performance refinements across SimConnect reads and device output.

v1.42

Haptic Engine
March 2026

New

  • SimConnect-based rotor impulse generation reading GENERAL_ENG_PCT_MAX_RPM:1.
  • Pause detection via ctypes, the only reliable method in MSFS 2024.
  • Autostart via exe.xml.
  • GUI with live pulse strength, rattle threshold and device dropdown.
  • Works with any 4-blade rotor helicopter in MSFS 2024, not restricted to the EC135.
