The XA41, also called Sbach 300, has a single-seat cockpit, 315 hp piston engine and fixed landing gear. Vertigo Design represents it separately from the tandem-seat XA42 / Sbach 342.
History & design
Sbach 300 and XA41 identify the single-seater
The single-seat XA41 belongs to the same XtremeAir aerobatic family as the tandem XA42. EASA's 2011 type-rating discussion already anticipated the combined XA41/42 designation while distinguishing the certification status of the two models. The familiar Sbach names therefore need to be matched to seat count and model identity.
EASA · CRD to NPA 2011-07, September 2011 ↗Historical naming and family relationship; the 2011 document does not establish current certification status.
Systems & details
A dedicated single-seat simulator model
Vertigo lists its XA41/Sbach 300 with a 315 hp engine and a 670 kg maximum weight. These are the developer's stated model figures. The tandem-seat Sbach 342 is a separate aircraft entry and should not supply this model's loading assumptions.
The single-seat simulator package
Vertigo’s XA41 listing supplies separate X-Plane 11 and X-Plane 12 versions and describes a three-dimensional cockpit, VR support and dynamic FMOD sounds. Those simulator editions belong to the same single-seat aircraft identity, but their availability does not by itself establish identical behaviour in both platforms. The store’s 315 hp and 670 kg model description should also remain attached to the XA41 rather than the two-seat XA42.

The simulator model and controls
The single-seat, 315 hp XA41 aerobatic aircraft.
How this profile feels
Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
Pitch-trim relief is off. Autopilot following is off.
Aircraft and configuration
Single-seat XA41,315hp, fixed gear. Distinct from tandem LivToAir XA42/Sbach342.
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.

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 value0.74 | What it controls and whyThis profile uses reversible-control loading for XtremeAir XA41. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 65 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 value0.8 | What it controls and whyThe aerodynamic-load gain is 0.8 with an indicated-speed reference of 160 KIAS. This supplies speed-dependent loading alongside the spring. |
| Force tuning speed/reference | Starting value160 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 value65 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 value1.0 | 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 valueDisabled | 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 |

XtremeAir XA41: Exact add-on trim-neutral geometry not established; relief off. Estimated pitch/roll trim authorities 0/0; 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 | What it controls and whyThe profile uses the trim behaviour configured below. Pitch relief is off, with stored authority 0; 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. |
XtremeAir XA41: 160 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 value160 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |
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 value8 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 value65 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 value0.15 | What it controls and whyThe high-speed spring-stiffening gain is 0.15. It strengthens the permitted spring response above 65 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 valueDisabled | 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 value0.1 | 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 value0.35 | 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 value3 | 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 value0.4 | What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration. |
| Gain | Starting value0.25 | What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact. |
| Gain | Starting value0.65 | 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 valueEnabled | What it controls and whyEnables engine cues with nonzero settings and valid running-engine telemetry. |
| Gain | Starting value0.12 | What it controls and whySets estimated engine vibration using configured telemetry and response, not measured cockpit vibration. |
| 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 | What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects. |
Limits and open questions
- XtremeAir XA41 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.
