A few places to begin, from the aircraft’s story to the people who fly it.
Meet the aircraft
The 412 developed from Bell's 212, replacing the earlier main-rotor arrangement with a composite four-blade system. The airframe found both civilian and military customers, and later versions introduced further cockpit and equipment changes. It belongs to the wider Huey family but has its own rotor, performance and systems context.

History & design
The EPX grows from a long utility lineage
Charles places the 412EPX within the Huey, 212 and 412 family. Bell and Subaru’s development work for Japan’s UH-2 also produced changes offered in the civil EPX, connecting a familiar airframe lineage with a newer programme.

Familiar Huey roots and a long trip home

Greg Maitlen accompanied the Arizona demonstration, which included photography, a mountain landing and a simulated engine failure. Bright sunlight made some autopilot buttons difficult to read, and Charles initially used more pedal movement than the helicopter needed.
The introduction continued with a lengthy ferry to Colorado. Mountain winds gave him another reason to appreciate the autopilot, while the absence of the optional fuel-flow display was something he noticed during the journey. By the end of the day, familiarity had grown into affection. His report balances that response with small cockpit frustrations and the conditions of the particular aircraft he flew.

A nighttime medical call brought McClendon and two nurses towards a road accident in rain showers. Information about obstacles at the proposed landing site was uncertain, and the urgency surrounding the patient added pressure. When the helicopter’s lights revealed power lines, he abandoned the approach and reconsidered how to reach the scene.
After landing, McClendon spoke with the firefighter who had been helping on the ground. The encounter changed the tone of his memory: the man was wet, tired and doing unfamiliar work under difficult circumstances. McClendon remained shaken by how close the approach had come to the wires. His recollection focuses on incomplete communication and the people involved, preserving the discomfort of the event without turning the eventual approach into a technique to copy.

Read the full account · Vertical ↗A night flight exposes a problem in the organisation
McClendon joined a programme where the chief pilot discouraged autopilot use, despite the Bell 412 having the equipment installed. Having used automation in other aircraft, he studied the manual and explored the system in clear weather. The experience made him question the assumptions that had kept it out of routine use.
Later, on a return flight around three in the morning, deteriorating visibility led him to use an instrument approach to an airport and arrange an ambulance transfer. Afterwards he concealed the autopilot use from his chief pilot, a detail that exposes the organisation’s poor climate for discussing experience. This is a different event from his power-line recollection.

The simulator model and controls
The 412 developed from Bell's 212, replacing the earlier main-rotor arrangement with a composite four-blade system. The airframe found both civilian and military customers, and later versions introduced further cockpit and equipment changes. It belongs to the wider Huey family but has its own rotor, performance and systems context.
This profile selects X-Trident Bell 412 for X-Plane 12.
How this profile feels
The spring stays independent of airspeed. Directed aerodynamic loading is omitted.
Local force trim is off. Autopilot following is off.
Cyclic damping is on. Its configured gain is 0.35; it resists hardware motion separately from the spring and aircraft stabilization.
Controls and trim
X-Trident describes its Bell 412 as a twin-turbine, four-blade helicopter on skids, with hydraulic, electrical and fuel systems and a custom four-channel autopilot. Its many modes belong to the aircraft's own guidance logic. Older improvement notes do not establish the units or meaning of a current servo target, and disabled Bridge following does not mean the add-on lacks an AFCS.
The selected implementation
X-Trident XP12 Bell412 has custom governor/failures/AP; differing summary/change-log dates do not establish current target units.
About the values
The gains are normalized profile settings. They describe the chosen effect balance; hand force depends on the device and its output limits. IAS references are tuning values rather than operating limits. Physical acceptance of this revision remains pending.
Documentary review and sources
These decisions describe the documentary basis and remaining gaps for this revision. Aircraft documentation and a starting setting describe different kinds of evidence.

Simulator integration
InheritedThe profile targets 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 value0.14 | What it controls and whyThe configured cyclic centre and damping provide nominal resistance for the selected four-bladed helicopter, separate from its guidance modes. The baseline spring is 0.14. Low-speed spring blending is off. |
| Master force gain | Starting value0.65 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| Profile force gain | Starting value0 | What it controls and whyThe 0 gain omits sustained directed airspeed loading. Spring resistance remains independent. |
| Force tuning speed/reference | Starting value120 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 value60.0 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. These stored weights do not create directed aerodynamic loading while that term is inactive. 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. |
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 value0.14 | What it controls and whyThe configured cyclic centre and damping provide nominal resistance for the selected four-bladed helicopter, separate from its guidance modes. The baseline spring is 0.14. Low-speed spring blending is off. |
| Spring deadband | Starting value0.02 | What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner. |
| Profile force gain | Starting value0 | What it controls and whyThe 0 gain omits sustained directed airspeed loading. Spring resistance remains independent. |
| Master force gain | Starting value0.65 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| QBlend Enabled | Starting valueDisabled | 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. |
| 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 value60.0 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Force tuning speed/reference | Starting value120 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |
| 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. |
| Aileron force scale | Starting value0.72 | What it controls and whyRoll and pitch aerodynamic scales are 0.72 and 1, respectively. These stored weights do not create directed aerodynamic loading while that term is inactive. 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. |
| Output force limit | Starting value0.55 | What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate. |
| 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. |
| 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. |
| Force Trim Enabled | Starting valueDisabled | What it controls and whyA local spring latch remains a reduced trim representation and does not reproduce the full four-channel AFCS. Local force trim is off. The stored latch parameters are inactive; the profile does not supply a local hold-where-left neutral. |
| 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 valueDisabled | 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 | 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 | 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
- X-Trident Bell 412; xplane12. Previously observed titles and implementation identifiers are retained; installed matching remains deferred.
- Powered cyclic with custom artificial stability. Animated rotor kinematics do not determine device torque.
- No exact add-on neutral-position contract established by the cited product source. Retain native aircraft trim handling and keep independent Bridge FTR/fixed-wing relief disabled by default; no cross-developer coefficient reuse.
- Custom four-channel AP with more than10modes; documented legacy improvements do not establish current servo-target datarefs. AP servo-follow and neutral hold remain disabled; engagement indicators are not force-demand signals.
- Bell412 XP12v5.2, twin turbine/four blades/skids, custom governor and failure systems. Store summary date2023 conflicts with changelog2024; preserve both. Actual rotor speed/frequency mapping remains unqualified; periodic gains stay off.
- 120 KIAS is an estimated feel reference, not cruise TAS or a certified limit. No invented Mach, VNE or weight scheduling.
- Read-only native telemetry for aircraft motion and accessory positions. Custom switches, display animations and mode lamps are not calibrated servo targets. No unverified LVars/datarefs or simulator writes.
- Spring 0.14; lateral scale 0.72; trim authorities 0/0; per-axis output cap .55. Editable engineering estimates, not measured hand forces. No body-rate torque, surface following or fabricated hydraulic-failure loads.
- New physical and installed-product checks deferred by owner. Existing separately recorded acceptance retains its original device, simulator, add-on and version limits. Source review does not broaden custom telemetry acceptance.
- Only actual accessory position changes drive movement texture; static drag and command-triggered kicks are disabled. Select and save an aircraft default when telemetry lacks a discriminating developer/configuration identity.
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.
