An American demonstrator joins the fleet

The first United States-registered H3, N361EX, appeared in October 2017 as an importer’s demonstrator in Cincinnati. The same release described deliveries to South Korea, France and China and an order from New Zealand, illustrating the type’s expansion beyond Belgium.

A small helicopter with conventional rotor controls

The H3 Sport pairs its four-blade anti-torque rotor with an automatic clutch and a governor. Dynali describes light control inputs and a cabin 1.30 m wide. The engine is modified for helicopter service, so its 135 hp rating should not be confused with an unmodified Rotax 912 ULS.

EasyFlyer, Sport and Open Air are not one specification

The figures here describe the manufacturer’s 135 hp H3 Sport. The Open Air has a different cabin treatment, while simulator packages may also include the earlier EasyFlyer. Match the selected aircraft’s documentation before borrowing weights, equipment or operating details from another version.

How the profile models it

VSKYLABS Dynali H3 EasyFlyer

Free + Pro
X-Plane 12VSKYLABS

The Dynali H3 is a compact helicopter offered in ready-to-fly and kit forms. Its side-by-side cabin and conventional tail rotor give it the familiar arrangement of a utility helicopter at a smaller scale.

This profile selects VSKYLABS Dynali H3 EasyFlyer for X-Plane 12.

The cyclic spring and damping approximate mechanical push-pull controls. The spring stays independent of airspeed. Directed aerodynamic loading is omitted. Cyclic damping adds resistance to hardware motion.

Governor selection is separate from trim; the acquired controls description does not establish an in-flight trim linkage. Local force trim is off. Autopilot following is off.

Controls and trim

Dynali documents push-pull cyclic and collective controls, adjustable friction and a rotor-sensed governor. The governor is an engine/rotor-regulation function. The preserved manufacturer and developer rotor-speed references differ, so they retain their named values and source context.

The selected implementation

The developer and manufacturer give different absolute rotor-speed references. The profile uses reported rotor percentage; the rotor-sensed governor remains separate from cyclic trim.

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.

Master gain & control system

Master gain65%

The final overall output scale applied to everything the model produces, before the device cap.

More: everything (spring, loads, effects) gets stronger together.

Less: everything softens together.

Why here: Scales overall profile strength while preserving effect balance, subject to device and output limits.

Forces

Spring strength12%

The base centring force that pulls the stick back to centre. Every other force stacks on it. Too low and the stick feels limp in normal flight; too high and it fights your hand and masks the smaller cues layered above it.

More: firmer centring that resists your hand at all times.

Less: a limper stick that leans on aerodynamic load alone.

Why here: The cyclic spring and damping approximate mechanical push-pull controls. The baseline spring is 0.12. Low-speed spring blending is off.

Developer POH systems/limitations; Cabri primary PDF110 printed7-4 or R66 section7 PDF9 printed7-7 where applicableDynali H3 EasyFlyer primary POH revision2.5VSKYLABS Aerospace Simulations Aircraft Center: VSKYLABS 'Test-Pilot': Dynali H3VSKYLABS Dynali H3. A High-Definition Ultralight Helicopter Simulation for X-Plane.
Spring deadband2%

A small neutral zone around centre where the spring stays quiet, so tiny movements at rest don't chatter. Wider is calmer but looser; narrower is more precise but can twitch around centre.

More: a calmer but looser centre with more free play.

Less: a tighter centre that may chatter at rest.

Why here: Sets travel around the centre before the baseline spring resists. Smaller values engage it sooner.

Overall aerodynamic load0%

A master scale over both sustained axis loads, applied before their independent balance. Profiles normally leave this alone and tune the two axis loads instead.

More: both axes load up harder.

Less: both axes lighten together.

Why here: The 0 gain omits sustained directed airspeed loading. Spring resistance remains independent.

Airspeed blendingFalse

Enables the low-speed spring engagement window (start/full knots above). Off, the spring is constant at all speeds.

Why here: Allows baseline spring strength to rise with indicated airspeed where the control law permits it.

Low-speed spring floor55%

How much of the spring survives at a standstill, before airspeed can build any aerodynamic force. A high floor keeps the parked stick firm; a low floor gives the loose, cable-slack feel of a parked light aircraft.

More: a firmer stick while parked and taxiing.

Less: a floppier parked stick that only wakes up with airspeed.

Why here: Sets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength.

Spring engagement start10 kt

The airspeed where the spring begins climbing from its low-speed floor toward full strength: the controls "coming alive" on the takeoff roll.

Why here: Sets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit.

Spring engagement full45 kt

The airspeed where the spring reaches full strength. Between the start and this point, centring firms up progressively as airflow builds over the controls.

Why here: Sets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.

Force tuning speed85

The indicated airspeed where aerodynamic load reaches its designed full level. It anchors the whole load curve to the aircraft's real speed range: a 172 loads up by 110 knots, a jet much later.

More: loads arrive later; the stick stays light up to a higher speed.

Less: loads arrive earlier and cruise feels heavier.

Why here: Sets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.

Centre firmness vs speed0%

How much the centring itself stiffens with speed, on top of the deflection loads. Zero keeps centre feel constant; more makes the stick centre harder at cruise and looser in the pattern.

More: a centre that hardens noticeably as you go faster.

Less: constant centre feel at every speed.

Why here: Adds permitted spring resistance above the full-blend speed. Zero removes this high-speed increase.

Centre stiffening cap2

The upper limit on speed-driven centre stiffening, so very fast flight can't wind the spring up without bound.

More: more total stiffening allowed at high speed.

Less: stiffening clamps off sooner.

Why here: Limits the squared airspeed ratio used for high-speed spring stiffening; it is not a device-force cap.

Aileron load100%

The sustained roll load from aileron deflection and airspeed, balanced independently of pitch. Together with the elevator load it sets the control-harmony ratio reviewers talk about.

More: heavier roll forces.

Less: lighter, quicker-feeling ailerons.

Why here: Roll and pitch aerodynamic scales are 1 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 load100%

The sustained pitch load from elevator deflection and airspeed, balanced independently of roll. This is the main lever behind a type's pitch weight. It does not touch aileron, spring, trim, or buffet forces.

More: heavier sustained pitch forces at speed.

Less: a lighter elevator that takes less muscle to hold.

Why here: Scales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.

Max output force55%

A cap on each steady pitch or roll force before it reaches the device, guarding against slamming or saturating the hardware in strong maneuvers.

More: stronger peak steady forces before clipping.

Less: a gentler ceiling; hard maneuvers flatten out sooner.

Why here: Caps directed-force output. Native spring effects and device limits remain separate.

Trim

Trim relief (elevator)0%

How strongly elevator trim relieves held pitch force and shifts where the stick settles. At 100%, a properly trimmed aircraft needs no held pressure, the trim-away-the-load workflow of real flying.

More: trim removes more of the held pitch force; at 100% full trim zeroes it.

Less: you keep holding force even when trimmed.

Why here: Scales supported pitch-trim relief and permitted centre movement. Zero removes pitch response.

Trim relief (aileron)0%

The same relief for roll trim. Most GA types have no real aileron trim, so this stays at zero; types with roll trim get a matching value.

More: roll trim removes more held roll force.

Less: roll trim does less.

Why here: Scales supported roll-trim relief and permitted centre movement. Zero removes roll response.

Effect gains · ground

Runway rumble0%

Rolling surface vibration from wheel speed and surface type: pavement, grass, or gravel under the gear.

More: louder surface texture through the stick.

Less: a smoother taxi.

Why here: Sets rolling texture strength, modified by speed, surface and undercarriage configuration.

Gear bumps0%

Short discrete bumps from expansion joints, ruts, and rough surface, punctuating the continuous rumble.

More: sharper hits from joints and ruts.

Less: softer ground detail.

Why here: Sets gear-bump texture during ground motion, separate from touchdown impact.

Effect gains · airframe

Stall buffet0%

Airframe shake approaching the stall and while the stall warning is active: how loudly this wing announces it is unhappy. Types with a crisp break get modest buffet and let the horn carry the warning.

More: a louder pre-stall shake.

Less: a quieter wing; the horn carries the warning.

Why here: Sets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings.

Mach buffet0%

Transonic buffet approaching the Mach limit. Meaningful for jets near MMO, zero for pistons and turboprops that never get there.

More: stronger transonic buffet near the Mach limit.

Less: a smoother high-Mach ride.

Why here: Sets high-Mach buffet strength; onset and full-strength thresholds are separate.

Flap buffet0%

Low-frequency airframe vibration with flaps extended into the airflow, in the speed window where they actually work the air.

More: a rougher ride with flaps working the air.

Less: smoother approach flap.

Why here: Sets flap buffet at the configured position and speed gates. Flap movement texture is separate.

Gear buffet0%

Airframe drumming from retractable gear hanging in the airstream. Zero for fixed-gear types, where the airframe never changes shape.

More: more drumming with the wheels hanging out.

Less: cleaner gear-down flight.

Why here: Sets gear aerodynamic buffet; movement and ground-contact cues are separate.

Stick shaker50%

The dedicated stall stick-shaker buzz, fired by the aircraft's own stall-warning system. Only types with a real shaker get a value; everything else relies on aerodynamic buffet and the horn.

More: a harder stick-shaker buzz.

Less: a subtler shaker.

Why here: Sets triggered shaker strength; inactive while the shaker feature is disabled.

Effect gains · engine, mechanical & drag

Touchdown thump20%

The one-shot kick when the wheels meet the runway, scaled by sink rate: a greaser whispers, a firm arrival thumps.

More: a harder kick at touchdown.

Less: softer arrivals.

Why here: Sets landing-impact strength; landing telemetry and response shape determine the pulse.

Reverse rumble0%

Rollout vibration while reverse thrust or beta-range props are working. Zero for types without reverse.

More: a rougher rollout under reverse.

Less: quieter reverse.

Why here: Sets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue.

Engine rumble0%

Continuous powerplant vibration following RPM between idle and full power, the ever-present reminder that something is burning fuel up front.

More: more engine through the stick.

Less: a quieter powerplant.

Why here: Sets estimated engine vibration using configured telemetry and response, not measured cockpit vibration.

Flap motion0%

Continuous vibration only while the sim reports the flap surfaces actually travelling. It follows real actuator motion and failures, not an estimated timer.

More: more vibration while the flap surfaces travel.

Less: quieter flap runs.

Why here: Sets texture from observed flap movement; a command without movement does not establish the cue.

Autopilot follow

AP follow authority5%

How far autopilot commands may physically move the stick. Kept tiny in MSFS, where a moved axis can read back as pilot input; zero disables following entirely.

More: the autopilot visibly moves your stick further.

Less: a barely perceptible follow.

Why here: Sets admitted AP-follow gain, not a percentage of travel. Runtime ownership and input limits still apply.

Stick feel

StickFeel · Trim feel enabledFalse

Whether this feature is active in this profile.

Why here: Retained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement.

StickFeel · Trim relief enabledFalse

Whether this feature is active in this profile.

Why here: Allows trim relief with supported control law and valid telemetry. Axis authorities set its amount.

StickFeel · Force trim enabledFalse

Whether this feature is active in this profile.

Why here: Governor selection is separate from trim; the acquired controls description does not establish an in-flight trim linkage. Local force trim is off. The stored latch parameters are inactive; the profile does not supply a local hold-where-left neutral.

StickFeel · G load enabledTrue

Whether this feature is active in this profile.

Why here: Allows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it.

StickFeel · Rate damping enabledFalse

Whether this feature is active in this profile.

Why here: Enables rate damping with the configured coefficients and control law.

Autopilot

Autopilot · Follow enabledFalse

Whether this feature is active in this profile.

Why here: Permits centering hold during a supported AP state, separate from following a moving target.

Autopilot · Neutral hold strength0.6

Why here: Sets admitted AP neutral-hold strength; inactive while neutral hold is disabled.

Aero

Aero · EnabledTrue

Whether this feature is active in this profile.

Why here: Enables aerodynamic cues; each still needs nonzero strength and its simulator conditions.

Aero · Max flap index1

Where this effect reaches full strength (or has fully faded, for washouts).

More: a more gradual build to a later peak.

Less: a quicker build.

Why here: Sets the final flap index for detent normalization. UP plus three detents uses maximum index3.

Aero · Min flap index1

Where this effect begins fading in.

More: the effect begins later.

Less: it begins earlier.

Why here: Sets the first flap detent that admits buffet; this is a handle index, not degrees.

Aero · Shaker enabledFalse

Whether this feature is active in this profile.

Why here: Permits shaker at supported warning conditions; the switch does not establish aircraft equipment.

Ground

Ground · EnabledTrue

Whether this feature is active in this profile.

Why here: Enables ground effects; each still needs its own strength and contact or motion telemetry.

Engine

Engine · EnabledTrue

Whether this feature is active in this profile.

Mechanical

Mechanical · EnabledTrue

Whether this feature is active in this profile.

Why here: Enables accessory cues with configured strengths and observed accessory movement.

Mechanical · Gain0

The strength of this effect.

More: a stronger effect.
