Complete cockpit and exterior sound replacement for the Nemeth Design EC135 in Microsoft Flight Simulator 2024.
The default EC135 turbine sounds are flat, simplistic, and completely unrealistic. They lack the depth and character of a real twin-turbine helicopter. This pack replaces them entirely — inside and out — with custom sound files mixed from real helicopter recordings.
From the cockpit, hear the turbines with goosebump-inducing realism through every flight phase: cold start, spool-up, idle, flight, and shutdown. From outside, the characteristic Eurocopter twin-engine whine and rotor wash transform replays, flyovers, and external views into a true experience.
COCKPIT TURBINE AUDIO:
- Custom cockpit turbine sounds designed for the EC135
- Custom startup sequence — hear the turbine spool from ignition to idle, mixed from real helicopter recordings
- Realistic startup and shutdown sequences — each phase authentic, correctly timed
- Seamless transition from starter to turbine run — no audio gaps, no cuts
- Smooth torque transitions — pitch variation reduced to 20% of stock for realistic twin-turbine behavior
EXTERIOR AUDIO:
- Full exterior sound replacement — the iconic Eurocopter twin-engine whine for replays, flyovers, and external views
- Rotor wash, flyby, and hover audio completely reworked
- Multiple custom sound files covering every external perspective
TECHNICAL:
- ButtKicker-safe — no artificial internal bass rumble that interferes with haptic setups
- Zero FPS impact — pure sound file replacement, no scripts, no plugins, no GPU load
- No dependencies, no third-party software needed
- Works seamlessly alongside the FWX Rotor Haptic Engine
ZERO SETUP — ONE-TIME CONFIGURATION:
- Drag-and-drop installer — point it at your Community folder, click Install
- v1. 44 installer walks you through the required Package Load Order step with a mandatory confirmation dialog — no more silent installs
- Instant uninstall — delete the folder or re-run the installer, and the original sounds return
- No installation wizard complexity, no frameworks, no leftovers

IMPORTANT — ONE-TIME PACKAGE LOAD ORDER SETUP:
The v1. 44 installer walks you through this with a mandatory confirmation dialog. If you install manually or need to reconfigure, follow these steps once after installation:
1. Go to General Options > Advanced Options > Package Reorder Tool
2. Enable the tool and uncheck 'Only Scenery Packages'
3. Search for '135'
4. Move the FWX Sound Pack below the Nemeth Design EC135
5. Restart the simulator
This ensures the custom sounds take priority over the default ones
