1. Mechanical & Airframe Effects¶

Effects driven by the mechanical state of the aircraft (engine vibration, moving surfaces and doors, damage, hydraulics) in the order they appear under the Mechanical\Airframe section of the Settings tab. The badge lines and sub-setting tables are generated from the application’s settings catalog, so they always match the app.

1.1 Controls Lock¶

MSFS · All devices

For aircraft with a control lock (gust lock): while the configured sim variable reports the lock engaged, TelemFFB holds the controls firmly in place.

Sub-setting	Sims	What it does
Controls Lock Simvar	—	Sim Variable for control locks
Invert Controls Lock Simvar	—	Enable if variable ON means Control Lock is OFF

1.2 Heli Engine/Rotor Rumble¶

DCS BMS MSFS XP · All devices

Helicopter engine and rotor vibration, driven by rotor RPM and blade count.

Sub-setting	Sims	What it does
Heli Engine/Rotor Rumble	—	peak rumble intensity for helicopter engine/rotor effect

1.3 Afterburner Rumble¶

DCS BMS MSFS XP · All devices

Rumble while the afterburner is lit, scaled by afterburner stage where the telemetry provides it.

Sub-setting	Sims	What it does
Afterburner Rumble	—	Max intensity of afterburner rumble effect

1.4 Engine Rumble - Shake Telemetry (IL-2)¶

IL2 · All devices

IL-2 exports its physics engine’s own computed engine-shake amplitude and frequency. These effects (one for props, one for jets) render that telemetry directly: startup lope, roughness, and damage arrive in the shake automatically. They are an alternative to the RPM-based rumble effects below: enable one or the other, not both.

Sub-setting	Sims	What it does
Shake Boost	—	Factor applied to “Engine Shake Amplitude” from game telemetry

Sub-setting	Sims	What it does
Shake Boost	—	Factor applied to “Engine Shake Amplitude” from game telemetry

1.5 Propeller Rumble¶

DCS IL2 BMS MSFS XP · All devices

RPM-driven piston-engine and propeller vibration. The two RPM/intensity pairs work together: at the Low RPM value the effect plays at Low Intensity, ramping toward High Intensity at the High RPM value. These are not floor values: below Low RPM (engine start, shutdown) the intensity keeps increasing above Low Intensity.

Tip

High-frequency vibration feels stronger than low-frequency vibration at equal intensity, so the High RPM intensity should be set lower than the Low RPM intensity.

Sub-setting	Sims	What it does
Engine Rumble Low RPM	—	low RPM threshold for low rpm intensity setting
Engine Rumble Low Intensity	—	peak intenstiy of engine rumble at low RPM threshold
Engine Rumble High RPM	—	high RPM threshold for high rpm intensity setting
Engine Rumble High Intensity	—	peak intensity of engine rumble at high RPM threshold

1.6 Jet Engine Rumble¶

DCS IL2 BMS MSFS XP · All devices

Turbine rumble scaled by engine power, at a configurable base frequency.

Sub-setting	Sims	What it does
Jet Engine Rumble	—	Intensity setting for the jet engine rumble effect
Jet Engine Rumble Freq	—	Frequency in Hz of the engine rumble effect

1.7 Canopy Motion¶

DCS XP · All devices

Vibration while the canopy is opening or closing.

Sub-setting	Sims	What it does
Canopy Motion	—	Peak vibration intensity when canopy is moving

1.8 Damage Effect¶

DCS IL2 BMS · All devices

A short bump in a random direction, at randomized intensity, each time the aircraft takes damage; some hits land harder than others by design.

Sub-setting	Sims	What it does
Damage Effect	—	Peak intensity of damage effect shake

1.9 Flaps Motion¶

DCS IL2 BMS MSFS XP · All devices

Vibration while the flaps are in motion.

Sub-setting	Sims	What it does
Flaps Motion	—	Peak vibration intensity when flaps are moving

1.10 Fuel Boom/Door Motion¶

DCS · Joystick

Vibration while the refueling boom receptacle or door is deploying or retracting.

Sub-setting	Sims	What it does
Fuel Boom/Door Motion	—	Effect while fuel boom/door is deploying/retracting

1.11 Gear Buffet¶

DCS BMS MSFS XP · All devices

Aerodynamic buffet from extended landing gear, growing with airspeed between the low- and high-intensity speeds.

Sub-setting	Sims	What it does
Gear Buffet	—	Peak intensity for gear drag buffeting effect
Buffeting Frequency	—	Frequency of buffeting effect (Hz)
Min Intensity Speed	DCS, BMS, MSFS	Minimum intensity (low) speed for gear buffeting effect
Max Intensity Speed	DCS, BMS, MSFS	Maximum intensity (high) speed for gear buffeting effect

1.12 Gear Motion¶

DCS IL2 BMS MSFS XP · All devices

Vibration while the gear is in transit, with clunks at the ends of travel.

Sub-setting	Sims	What it does
Gear Motion	—	Peak vibration intensity when gear is moving

1.13 Speedbrake Buffet / Speedbrake Motion¶

DCS BMS XP · All devices

Buffet while the speed brake is deployed, and vibration while it is moving.

Sub-setting	Sims	What it does
Speedbrake Buffet	—	Peak intensity for speed brake buffeting effect

Sub-setting	Sims	What it does
Speedbrake Motion	—	Peak intensity for speed brake motion effect

1.14 Spoiler Buffet / Spoiler Motion¶

DCS BMS MSFS XP · All devices

Buffet while spoilers are deployed, and vibration while they move (motion effect currently F-14 only).

Sub-setting	Sims	What it does
Spoiler Buffet	—	peak buffeting intensity when spoilers deployed

Sub-setting	Sims	What it does
Spoiler Motion	—	F14 Only, peak vibration intensity when spoilers are moving

1.15 Stick Shaker¶

DCS BMS MSFS · Joystick, Pedals

A stall-warning stick shaker: the distinct high-frequency square-wave shake of the real device, separate from the aerodynamic AoA/Stall Buffeting. In MSFS it triggers from the sim’s stall warning; DCS/BMS use the configurable AoA threshold.

Sub-setting	Sims	What it does
Stick Shaker Intensity	—	Enable stick shaker stall warning device
Shaker AoA Threshold	DCS, BMS	AoA at which stick shaker activates
Shaker Freqency (Hz)	DCS, BMS	Freqency in Hz of the effect

Wing Fold Motion	—	Effect while wing-fold is deploying/retracting

1.17 Low Hydraulic Pressure Effect (Experimental)¶

DCS BMS MSFS · All devices

Simulates the heavy, sluggish controls of a failing hydraulic system: as the HydSys telemetry value falls from the configured threshold toward zero, the damper, inertia, and friction forces ramp from their normal values toward the levels configured here.

Sub-setting	Sims	What it does
Hydraulic System Threshold	—	“Hydraulic System Integrity” (HydSys in monitor) value to consider “low”. Forces will start increasing below this value
Damper	—	Damper force when hydraulic system pressure reaches 0
Inertia	—	Inertia force when hydraulic system pressure reaches 0
Friction	—	Friction force when hydraulic system pressure reaches 0

Note

Requires the damper/inertia/friction overrides to be enabled, and headroom left in them; if your base forces already sit at 100%, there is no room to increase them. To set the threshold for a new aircraft, observe the normal HydSys value in the Monitor tab and set the threshold below it.

Warning

Increase these forces carefully; too much inertia or friction can cause motor instability and a protective shutdown.

1.18 Vibration from Telemetry (FlyInside)¶

MSFS · All devices

For FlyInside helicopters in MSFS: renders the vibration data exported by the FlyInside flight model directly. See FlyInside Helicopters.

Sub-setting	Sims	What it does
Vibration Intensity	—	Intensity of Helicopter Vibration (from external flight model) Max intensity controlled by Constant slider in Configurator
Vibration Expo	—	Force exponential value. 0 = linear gain, at 0.5, it rises 2x as much in the low end. Negative values decrease force up to 1/3x.
