A few places to begin, from the aircraft’s story to the people who fly it.
Aircraft and simulator background
The UH-12 developed from Hiller's Model 360. Nemeth's aircraft background records its first flight in 1948 and its subsequent military and civilian utility roles. The piston-powered family also served as the H-23 Raven, with the B model used prominently in training.

History & design
From the Model 360 to the Raven
The developer's background traces the UH-12 to Hiller's Model 360 and dates its first flight to 1948. The H-23 Raven served utility, observation and medical-evacuation roles during the Korean War. Later variants continued in training and scout work, with the H-23B identified as a training helicopter.

Rotor-Matic and early utility work
Hiller’s early experiments progressed from counter-rotating rotors to a single-main-rotor design, using the J-5 testbed to address stability and control. The Hiller Aviation Museum dates UH-12 certification to 1948 and records more than 2,000 built. Its Rotor-Matic system placed small control paddles at right angles to the main blades; cyclic inputs changed those paddles to help control the rotor.
The type’s utility work included Valerie André’s aeromedical evacuation operations in French Indochina and Raven service in Korea. The museum’s published performance table is specifically for the OH-23D, so its 250 hp engine and weights are not used here as UH-12B specifications.

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 | What it controls and whyNemeth's product title names the UH-12B and support for MSFS 2020 and 2024. The baseline spring is 0. Its low-speed blend reaches baseline strength at 32.5 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 value0.35 | What it controls and whyThe aerodynamic-load gain is 0.35 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 value32.5 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 value1 | What it controls and whyRoll and pitch aerodynamic scales are 1 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 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. |

Hiller UH-12B Civil Utility: 65 indicated knots is the inherited control-feel reference; it is not cruise TAS, a flight limit or a measured load threshold. Speed scheduling remains an editable estimate.
| 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. |
| QSpring Start Knots | Starting value9.1 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 value32.5 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
Hiller UH-12B Civil Utility: exact trim axes, mechanism and portable telemetry contract are unresolved in the inspected source. Trim feel, trim relief, force trim and hydraulic centering are disabled for this generic choice.
| Setting | Starting value | What it controls and why |
|---|---|---|
| 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 whyNemeth's product title names the UH-12B and support for MSFS 2020 and 2024. Local force trim is off. The stored latch parameters are inactive; the profile does not supply a local hold-where-left neutral. |
| Autopilot follow | Starting valueDisabled | What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel. |
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 value0.02 | What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner. |
| 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 value1 | What it controls and whySets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength. |
| Airspeed spring stiffening gain | Starting value0 | What it controls and whyAdds permitted spring resistance above the full-blend speed. Zero removes this high-speed increase. |
| 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. |
| Elevator Authority | Starting value0 | What it controls and whyScales supported pitch-trim relief and permitted centre movement. Zero removes pitch response. |
| Aileron Authority | Starting value0 | What it controls and whyScales supported roll-trim relief and permitted centre movement. Zero removes roll response. |
| GLoad Enabled | Starting valueDisabled | 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 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 | 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 value1 | What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3. |
| Minimum flap index | Starting value1 | 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 | What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration. |
| Gain | Starting value0 | 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 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
- The source also describes military observation history; this manually selected fallback is restricted to civil utility/training and does not cover a weapons configuration.
- Generic airframe starting scope; exact installed add-on matching, custom signals and device operation remain unqualified.
- Force magnitudes and scheduling are inherited estimates. No physical calibration or certification is claimed.
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.
