History & design
Integrating the electric sustainer
The Discus-2c FES first flew on 5 November 2015 with Schempp-Hirth engineer Joachim Krauter at the controls. The manufacturer had already used LZ Design's sustainer in the Ventus-2cxa. The integration brought the electric motor into the Discus-2c's cross-country sailplane configuration.

The simulator model and controls
A sailplane family with an optional nose-mounted electric sustainer.
How this profile feels
Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
Valid trim provides the configured pressure relief. Autopilot following is off.
Aircraft and configuration
Unpowered sailplane, retractable main wheel, no flaps, airbrakes and water ballast.
The two simulator editions
Standard is unpowered, while Premium adds 22 kW electric in-flight assistance. Spring elevator trim, mid-wing airbrakes and retractable gear accompany the airframe. The manual documents FES power, temperature and folding-propeller behaviour.
Later software compatibility

About the values
Strengths are normalized hardware-feel settings. They set the effect balance; hand force depends on the device and its limits. The IAS reference is a tuning value.
What the documentation establishes
Schempp-Hirth Discus-2c Unpowered: Unpowered sailplane, retractable main wheel, no flaps, airbrakes and water ballast.

Speeds and limits
InheritedThe indicated-speed references set the profile response scale; they are separate from aircraft operating limits.
Simulator integration
ReviewedThe profile targets msfs2020, msfs2024, xplane12. Add-on-specific controls use only the supported references configured by this profile.
Force-feedback settings
InheritedThe settings define the profile’s effect balance. Device output limits affect physical hand force.
Starting settings and their rationale
These configured values are starting estimates. The explanations describe what each setting controls; physical validation appears separately below.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring strength | Starting value0.64 | What it controls and whyStandard is unpowered, while Premium adds 22 kW electric in-flight assistance. The baseline spring is 0.64. Its low-speed blend reaches baseline strength at 55 KIAS. |
| Master force gain | Starting value0.85 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| Profile force gain | Starting value1 | What it controls and whyThe aerodynamic-load gain is 1 with an indicated-speed reference of 65 KIAS. This supplies speed-dependent loading alongside the spring. |
| Force tuning speed/reference | Starting value65 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |
| Spring response reference speed | Starting value55 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Aileron force scale | Starting value0.72 | What it controls and whyRoll and pitch aerodynamic scales are 0.72 and 1, respectively. They set the aerodynamic axis balance. No custom spring-travel curve is enabled. |
| Elevator force scale | Starting value1 | What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings. |
| Trim feel | Starting valueDisabled | What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement. |
| Trim relief | Starting valueEnabled | What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount. |
| Autopilot follow | Starting valueDisabled | What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel. |
| Autopilot neutral hold | Starting valueDisabled | What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target. |
| Output force limit | Starting value0.55 | What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate. |
All 44 starting settings and their rationale
The settings define the profile’s effect balance. Device output limits affect physical hand force.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring strength | Starting value0.64 | What it controls and whyStandard is unpowered, while Premium adds 22 kW electric in-flight assistance. The baseline spring is 0.64. Its low-speed blend reaches baseline strength at 55 KIAS. |
| Profile force gain | Starting value1 | What it controls and whyThe aerodynamic-load gain is 1 with an indicated-speed reference of 65 KIAS. This supplies speed-dependent loading alongside the spring. |
| Elevator force scale | Starting value1 | What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings. |

Schempp-Hirth Discus-2c Unpowered: Trigger trim uses INCREASE TACAN1 VOLUME, but this profile neither binds it nor implements the separately deferred glider button-trim feature. Estimated pitch/roll trim authorities 0.3/0; exact add-on sign, travel, units and build-specific neutral remain unqualified. Rudder trim never substitutes for roll trim.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Elevator Authority | Starting value0.3 | What it controls and whyStandard is unpowered, while Premium adds 22 kW electric in-flight assistance. Pitch authority 0.3 provides load relief and permitted centre movement; roll authority is 0. |
| Aileron Authority | Starting value0 | What it controls and whyScales supported roll-trim relief and permitted centre movement. Zero removes roll response. |
Schempp-Hirth Discus-2c Unpowered: 65 KIAS is the retained estimated tuning reference. It is not published cruise TAS, VNE, a new flight limit or a measured force threshold. Source-specific operating quantities remain attached to their original configuration and conditions.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Force tuning speed/reference | Starting value65 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |
Combustion-engine texture is disabled for the unpowered starting point.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Gain | Starting value0 | What it controls and whyCombustion-engine texture is disabled for the unpowered starting point. |
Exact configured values with software explanations. Force magnitudes remain editable estimates; disabled features retain inactive values.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring deadband | Starting value0.04 | What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner. |
| Master force gain | Starting value0.85 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| QBlend Enabled | Starting valueEnabled | What it controls and whyAllows baseline spring strength to rise with indicated airspeed where the control law permits it. |
| QSpring Minimum Factor | Starting value0.55 | What it controls and whySets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength. |
| QSpring Start Knots | Starting value25 kt | What it controls and whySets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit. |
| Spring response reference speed | Starting value55 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Airspeed spring stiffening gain | Starting value0.3 | What it controls and whyThe high-speed spring-stiffening gain is 0.3. It strengthens the permitted spring response above 55 KIAS, with the squared-speed ratio capped at 5. |
| Airspeed spring stiffening limit | Starting value5 | What it controls and whyLimits the squared airspeed ratio used for high-speed spring stiffening; it is not a device-force cap. |
| Trim feel | Starting valueDisabled | What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement. |
| Trim relief | Starting valueEnabled | What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount. |
| Force Trim Enabled | Starting valueDisabled | What it controls and whyEnables local force trim, separate from aircraft-owned trim and add-on integration qualification. |
| GLoad Enabled | Starting valueEnabled | What it controls and whyAllows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it. |
| Rate Damping Enabled | Starting valueEnabled | What it controls and whyEnables rate damping with the configured coefficients and control law. |
| Autopilot follow | Starting valueDisabled | What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel. |
| Autopilot follow authority | Starting value0.05 | What it controls and whySets admitted AP-follow gain, not a percentage of travel. Runtime ownership and input limits still apply. |
| Autopilot neutral hold | Starting valueDisabled | What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target. |
| Autopilot neutral hold strength | Starting value0.6 | What it controls and whySets admitted AP neutral-hold strength; inactive while neutral hold is disabled. |
| Enabled | Starting valueEnabled | What it controls and whyEnables aerodynamic cues; each still needs nonzero strength and its simulator conditions. |
| Gain | Starting value0.4 | What it controls and whySets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings. |
| Gain | Starting value0 | What it controls and whySets high-Mach buffet strength; onset and full-strength thresholds are separate. |
| Gain | Starting value0 | What it controls and whySets flap buffet at the configured position and speed gates. Flap movement texture is separate. |
| Maximum flap index | Starting value6 | What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3. |
| Minimum flap index | Starting value2 | What it controls and whySets the first flap detent that admits buffet; this is a handle index, not degrees. |
| Gain | Starting value0 | What it controls and whySets gear aerodynamic buffet; movement and ground-contact cues are separate. |
| Shaker Enabled | Starting valueDisabled | What it controls and whyPermits shaker at supported warning conditions; the switch does not establish aircraft equipment. |
| Stick shaker amplitude | Starting value0.5 | What it controls and whySets triggered shaker strength; inactive while the shaker feature is disabled. |
| Enabled | Starting valueEnabled | What it controls and whyEnables ground effects; each still needs its own strength and contact or motion telemetry. |
| Gain | Starting value0.3 | What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration. |
| Gain | Starting value0.3 | What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact. |
| Gain | Starting value0.5 | What it controls and whySets landing-impact strength; landing telemetry and response shape determine the pulse. |
| Gain | Starting value0 | What it controls and whySets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue. |
| Enabled | Starting valueDisabled | What it controls and whyEnables engine cues with nonzero settings and valid running-engine telemetry. |
| Enabled | Starting valueEnabled | What it controls and whyEnables accessory cues with configured strengths and observed accessory movement. |
| Gain | Starting value0 | What it controls and whySets texture from observed flap movement; a command without movement does not establish the cue. |
| Gain | Starting value0.12 | What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects. |
Limits and open questions
- Schempp-Hirth Discus-2c Unpowered is a universal starting point; exact add-on matching, edition operation and physical hand-force calibration remain unqualified.
- Autopilot movement and unknown custom trim, failure or force-input signals are disabled. Confirm the selected equipment fit and trim direction for the implementation in use.
- Force magnitudes and speed tuning are editable inherited estimates. Owner physical and installed-aircraft acceptance remain pending.
Physical validation
No physical force validation is recorded in this public catalogue for this revision. Documentary review and software checks do not establish how a particular device feels.
