Complete cockpit and exterior sound replacement compatible with the Nemeth Design EC135 for 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.
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.
Features:
• Custom cockpit turbine sounds – designed to be compatible with the EC135
• Custom startup sequence – hear the turbine spool from ignition to idle, mixed from real helicopter recordings
• Realistic turbine startup and shutdown sequences
• Authentic cockpit and exterior engine sounds
• Smooth torque transitions – pitch variation reduced to 20% of stock (realistic)
• Smooth torque transitions with reduced pitch variation
• Seamless transition from starter to turbine run – no audio gaps
• No internal bass rumble – ButtKicker/transducer safe
• Full exterior sound replacement — the iconic EC135 twin-turbine whine for replays, flyovers, and external views
• Full exterior sound — replays and external views come alive
• Drag & drop installation – copy folder to Community, done
• Simple drag-and-drop installation
• No dependencies, no third-party software needed
• Instant uninstall – delete the folder, original sounds are back
• Instant uninstall — delete folder, default sounds return
• Multiple custom sound files – compatible with the EC135
• No FPS impact – zero GPU load
• Free updates – we keep improving the sound as MSFS evolves
