Both products together, at a discount: authentic twin-turbine audio AND physical rotor feedback through your seat. For the Nemeth Design EC135 in Microsoft Flight Simulator 2024.
Hear every blade pass from the cockpit. Feel every blade pass through your seat. This is the complete EC135 experience — two complementary products designed to work together, developed by the same pilot, tuned to not interfere with each other.
Save over 15% compared to buying separately.
WHAT YOU HEAR — Sound Enhancement (included):
- Complete cockpit and exterior sound replacement
- Independent twin-turbine audio — each engine spools up individually during startup and shutdown
- Custom startup sequence mixed from real helicopter recordings
- Realistic startup and shutdown sequences with correct timing
- Smooth torque transitions — pitch variation reduced to 20% of stock
- Seamless transition from starter to turbine run, no audio gaps
- Full exterior sound replacement — iconic Eurocopter twin-engine whine for replays, flyovers, and external views
- ButtKicker-safe — no internal bass rumble that would interfere with the Haptic Engine
- Zero FPS impact
WHAT YOU FEEL — Rotor Haptic Engine (included):
- 4 physical impulses per rotor revolution — matches the real EC135 4-blade main rotor
- Real-time SimConnect integration — reacts instantly to rotor speed changes
- Low RPM startup: individual blade thumps, slow enough to count
- 30-50% RPM: irregular blade rattle of hanging blades
- Full RPM: smooth continuous bass pulse matching the rotor disc frequency
- Rotor brake feedback with gradual deceleration
- Auto-shutdown when MSFS exits, auto-silence in menus and loading screens
- Camera-aware, engine-state-aware, loading-screen protection
ZERO SETUP — ONE INSTALLER:
- Single installer for both components — install once, both products configured
- Guided Package Load Order dialog with mandatory confirmation (v1.45) — no silent installs
- Prerequisites self-check before installation begins
- Autostart registration via exe.xml for the Haptic Engine
- Independent uninstall — remove either component separately without affecting the other
- Installer runs with administrator privileges for guaranteed write access
LIVE RPM GUI (Haptic component):
- Real-time RPM display with impulse visualization
- Volume, bass, and impulse strength controls
- Device selection dropdown for multi-output setups
- All settings saved between sessions
Designed exclusively for the Nemeth Design EC135 (Local Legend 21) in Microsoft Flight Simulator 2024. The Haptic Engine works with any helicopter in MSFS 2024 — built around the EC135 but the rotor impulse function is universal.
Developed and tested by a real-world helicopter pilot (PPL(H) R22/R44) with thousands of hours in flight simulation.
Free updates — new sound content and haptic improvements included at no extra cost as MSFS evolves. New sound content is already in development for an upcoming update.
Featured on SimFlight, Threshold, MSFS Addons, MSFS Gateway, Sinclair Design, AVSIM, and r/MicrosoftFlightSim.

IMPORTANT — ONE-TIME PACKAGE LOAD ORDER SETUP:
The v1.45 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. Open MSFS 2024
2. Go to General Options > Advanced Options > Package Reorder Tool
3. Enable the tool and uncheck 'Only Scenery Packages'
4. Search for '135'
5. Move the FWX Sound Pack below the Nemeth Design EC135
6. Restart the simulator
This ensures the custom sounds take priority over the default ones
