Read this Development report by IndiaFoxtEcho Visual Simulations:
Development of the DCS: G.91R has entered an exciting new phase. The project is no longer focused solely on individual features. The flight model, engine, cockpit systems, hydraulics, fuel system, weapons and damage simulation are working together as one aircraft.
IndiaFoxtEcho Visual Simulations’ goal remains clear: to recreate the distinctive personality of the G.91—a compact, responsive and remarkably versatile tactical jet that is easy to enjoy, but rewarding to truly master.
Flight Model
The DCS: G.91R features a fully custom External Flight Model built around the aircraft’s individual aerodynamic surfaces. Wings, tail, fuselage, flaps, landing gear and airbrakes all contribute independently to the forces acting on the aircraft. This allows configuration changes, asymmetric loads and local damage to affect handling naturally.
The model includes progressive stall behaviour, wing drop, autorotation, spin tendencies, ground effect and transonic changes. Control effectiveness and aerodynamic damping evolve with speed and airflow, helping the aircraft feel light and agile without becoming artificial or predictable.
The result is a jet that communicates with the pilot. It rewards smooth flying, but it can also become demanding when pushed beyond its limits.
Orpheus Engine and JATO
The Bristol Siddeley Orpheus simulation has continued to mature. Engine response is influenced by altitude, airspeed, inlet conditions and pilot handling. RPM and Jet Pipe Temperature evolve progressively, while aggressive manoeuvres or poor inlet conditions can produce compressor disturbances, surges and flameouts. Abnormal operation is also transmitted through cockpit vibration, giving the pilot physical feedback before the instruments tell the whole story.
The G.91R/1B now includes a complete four-rocket JATO installation. The system has its own electrical controls, READY indication, ignition sequence, cockpit vibration and jettison logic. Each rocket contributes thrust from its actual location and orientation on the aircraft. Lighting four JATO rockets beneath a small tactical jet makes for one of the most dramatic experiences currently available in the module—and certainly one of the loudest.
Aircraft Systems
IndiaFoxtEcho Visual Simulations has also made major progress on the electrical, hydraulic, and fuel systems. Cockpit controls are connected to the systems they operate rather than acting as isolated animation triggers. Electrical buses, switches, relays and circuit protection determine whether equipment is genuinely available.
The hydraulic simulation now supports flight-control servos, landing gear, flaps, wheel brakes, emergency braking and accumulator-powered emergency functions. Loss of electrical power does not necessarily prevent a mechanical control from moving, but it may prevent the associated system from responding.
The fuel system now models the main tanks, pumps, transfer paths and supply logic, allowing fuel delivery to the engine to depend on the actual state and configuration of the system rather than on a simple global fuel quantity.
Normal and emergency operation are therefore becoming meaningful parts of flying the aircraft, rather than simple scripted events. Cockpit instrumentation has expanded alongside these systems, including engine, trim, flap, airbrake, hydraulic-pressure, fuel and flight-condition indications. Cold-and-dark and hot-start configurations also establish the aircraft's appropriate initial state.
Weapons with Period Personality
Weapon development has concentrated heavily on the G.91R/1B, currently the most complete test platform. Its internal guns, bombs, podded rockets and externally mounted rockets follow their dedicated cockpit circuits, selectors and release sequences. Bombs can be released individually or together, while rocket firing supports single, automatic and grouped modes with correct left-right sequencing.
Ground firing is inhibited by the landing-gear microswitch, while selective, salvo and emergency jettison functions follow their own operating rules.
The Nord AS-20 adds an entirely different kind of challenge. This early manually guided missile requires the pilot to launch, visually track and steer the weapon all the way to the target. It is demanding, unconventional and extremely satisfying when everything comes together. The R/4 also retains its dedicated Sidewinder capability, while the PAN, R/1B, R/3 and R/4 continue to receive separate equipment and system configurations appropriate to each version.
Structural Damage
The structural damage model has progressed from preparation into active integration. Instead of relying only on generic damage thresholds, the aircraft tracks loads acting on important parts of the airframe. High-G manoeuvres, asymmetric stores, excessive speed with flaps extended and battle damage can progressively reduce structural integrity. Damage can therefore influence the aircraft before complete failure occurs. A damaged wing or control surface may change the way the aircraft flies, forcing the pilot to adapt and carefully bring the jet home.
What Comes Next
The next stage of development by IndiaFoxtEcho Visual Simulations will focus on the PHI navigation system and ADF, while further expanding the pressurization and oxygen systems. Development of the damage model will also continue, extending beyond the aircraft structure to progressively include the surrounding systems and their interactions.
The G.91 is becoming much more than a small vintage fighter. It is shaping into a lively, hands-on tactical aircraft with guns, rockets, manually guided missiles, emergency systems—and four JATO rockets waiting beneath the fuselage.
Looking for a persistent war where every sortie, strike, and rescue operation leaves a lasting mark? Check out Vector Strike, a dynamic 24/7 multiplayer campaign built to deliver hardcore tactical warfare without the server lag.
What Makes Vector Strike Unique?
Engineered for Pure Performance: Forget the server stutters and lag spikes common in script-heavy campaigns. Unlike traditional servers that overload DCS with complex, CPU- and RAM-intensive Lua scripts, Vector Strike runs on a purpose-built external platform. By processing heavy campaign logic, AI tracking, and dynamic territory calculations off the main game thread, pilots enjoy silky-smooth frame rates, high tick rates, and uninterrupted flight even during massive multi-squadron battles.
Networked IADS & Dynamic Air Defense Takeovers: SAM sites don't sit with search radars blaring. They share a live sensor picture across Early Warning networks, go dark to ambush intruders, drop emissions against incoming HARMs, and deploy short-range point defense to shoot down incoming ordnance.
Capture & Repurpose: SAM sites are capturable tactical objectives. Soften an enemy site and insert ground troops via helicopter to secure it. The "Tech" troops then repurpose that SAM site to work for the aggressor. For example: If REDFOR captures a BLUEFOR Patriot battery, that exact battery instantly re-arms, links to Red’s EWR network, and starts locking and engaging Blue jets to lock down the airspace for the advancing frontline.
Combat Search & Rescue (CSAR) with True Impact: Ejecting spawns a live pilot unit at your crash site. Rotary-wing crews can coordinate via the in-game CSAR menu, pop smoke, extract survivors under fire, and deliver them back to friendly airfields or FARPs to restore vital role-based pilot lives.
Living Logistics & Frontline Conquest: Objectives only fall when ground forces move in. Interdict automated supply convoys, level enemy industrial complexes, sling-load supplies to forward FARPs, and air-assault infantry squads directly into contested zones to capture and hold territory.
Cockpit-Integrated JTAC & Real-Time EWR: Coordinate seamlessly from the cockpit using intuitive F10 radio menus and chat commands to request laser designation, IR illumination, 9-line CAS coordinates, and artillery fire-for-effect.
Live Interactive Ops Dashboard: Plan your next sortie using the real-time web dashboard at vectorstrike.org, complete with live NATO tactical symbology, active threat rings, kill feeds, and detailed pilot leaderboards.
