-===== Variants =====
+===== Operator Adjustment & Field-Service Ethos =====
-Hydra engines follow a numerical designation corresponding to cylinder count.
+A defining feature of all Hydra engines—V-Series and later F-Series—is the
-All early-war variants use a **V-configuration** by default, with select V8 and
+**operator adjustment screw** built directly into the throttle linkage.
-V12 models offered in **X configurations** for aviation or confined spaces.
+RRCC designed this deliberately, believing that a person who buys an engine
+should be able to **access its full capability** if they choose to accept the
+tradeoffs.
-  * **Hydra-4** – ~120 HP class
+From the factory, every Hydra is tuned to RRCC’s conservative standard
-    * Compacts, light machinery, small generators, Lynx (economy trims)
+(approximately 60% of the engine’s true capability), ensuring long service life
+under harsh conditions. Turning the adjustment screw allows the owner to take
+the engine **up to the recognized industry maximum**, with the understanding
+that increased performance may shorten the engine’s overall lifespan. So long as
+the screw remains within the marked RRCC range, warranties remain valid; beyond
+that point, the engine is the owner’s to command as they see fit.
-  * **Hydra-6** – ~200 HP class
+This philosophy comes from necessity, not marketing. Emberstone’s frontier
-    * Standard sedans, mid-range civilian vehicles, small tractors, utility craft
+conditions demanded machines that could be **repaired by anyone**, anywhere:
+soldiers in mud-soaked trenches, caravan drivers on unmarked roads, settlers a
+week’s ride from the nearest workshop. RRCC considered a machine worthless if it
+could not be kept running with nothing more than basic tools, spare parts, and a
+bit of ingenuity.
-  * **Hydra-8** – ~280 HP class
+Hydras were therefore built with:
-    * Performance cars, armored utility vehicles, medium trucks, naval auxiliaries
-    * Optional X-formation for aircraft or tight hull compartments
-  * **Hydra-12** – ~400 HP class
+  * **Accessible components** that can be removed in the field
-    * Heavy trucks, early armored vehicles, industrial equipment, small locomotives
+  * **Oversized tolerances** to survive improvised repairs
-    * Optional X-formation for aircraft and submarines
+  * **Replaceable modules** shared across multiple engine sizes
+  * **Clear markings** for safe adjustment, tuning, and emergency operation
-  * **Hydra-16** – ~600 HP class
+This approach later helped the F-Series boxers gain rapid acceptance. While
-    * RRCC *Dragon* luxury motor-carriages, heavy locomotives, surface ships, experimental craft
+smaller and less powerful than their V-Series cousins, they embodied the same
-    * Also used in dual-tandem arrangements for naval and rail applications
+RRCC philosophy: if the operator can reach it, they should be able to fix it,
+tune it, and—when needed—push it harder to get themselves home.
+In Emberstone, a vehicle that cannot be repaired on the roadside is considered a
+failure of design. RRCC ensured Hydra would never suffer that reputation.

+===== Variant Families =====
+Hydra engines fall into **two parallel families**:
+  * The original **V-Series** → larger, taller, more powerful; the Industrial War workhorses.
+  * The later **F-Series** → compact boxer engines introduced mid-war for small vehicles, carts, and generators.
+Both follow a numerical designation based on cylinder count.
+----
+===== V-Series (Original Hydra Line) =====
+Early-war standard. V-configuration unless otherwise noted.
+  * **Hydra-2 (V2)** – ~60 HP class
+    * Light generators, handheld machinery, microcars
+  * **Hydra-4 (V4)** – ~120 HP class
+    * Early Lynx (first model years), heavy generators, compact machinery
+    * Phased out of Lynx in favor of the F-Series once released
+  * **Hydra-6 (V6)** – ~200 HP class
+    * Sedans, mid-range civilian vehicles, small tractors, utility craft
+  * **Hydra-8 (V8)** – ~280 HP class
+    * Fox series trucks (heavier trims), armored utility vehicles, medium haulers
+    * Optional X-configuration for aircraft or tight hulls
+  * **Hydra-12 (V12)** – ~400 HP class
+    * Timberwolf trucks, early armored vehicles, locomotives
+    * Optional X-layout for aviation/naval constraints
+  * **Hydra-16 (V16)** – ~600 HP class
+    * *Dragon* luxury motor-carriages, locomotives, ships
+    * Also used in tandem pairs for naval and rail applications
+The V-Series remains RRCC’s flagship line, used wherever torque, longevity, and
+sheer displacement matter more than compact dimensions.
+----
+===== F-Series (Flat / Boxer Engines) =====
+Introduced in the later years of the Industrial War after internal RRCC research
+demonstrated the need for a **compact, low-profile, easy-to-service engine** for
+small craft, trench equipment, and utility vehicles.
+All F-Series engines are **air-cooled boxer style**, running cooler and smoother than
+their V-Series equivalents at a cost of less power than the V series.
+  * **F-2** – ~40 HP class
+    * RRCC tune: ~25 HP
+    * **Primary engine for:**
+        - Motorcycles
+        - Portable generators
+        - Pump units
+        - Small tools
+  * **F-4** – ~80 HP class (Industry Standard)
+    * RRCC tune: ~60 HP
+    * **Primary engine for:**
+        - Mules / trench carts
+        - Fox Mini / Kei-style light trucks
+        - Early Lynx after F-Series release (economy trims)
+        - Small boats, runabouts, industrial carts
+  * **F-6** – ~120 HP class (Industry Standard)
+    * RRCC tune: ~100 HP
+    * **Primary engine for:**
+        - Lynx sedans, wagons, and Utes
+        - Mid-range Fox trucks (standard trims)
+        - Light service vehicles and small cargo haulers
+The F-Series gave Emberstone its first true “people’s engines”—compact, easy to
+maintain, smooth-running, and extremely forgiving.

+==== Civilian Vehicles ====
+  * **Lynx (post-F-Series release)**
+    * Standard trims: **F-4 / F-6**
+    * Premium trims: optional **V-4 or V-6** early on, later standardized to F-Series

+    * Specialty heavy-duty builds: **V-12** (rare, custom contracts)
+  * **Timberwolf (1.5-ton+ trucks)**
+    * Always V-Series: **V-8, V-12**, or paired configurations
+  * **Dragon Motor-Carriage**
+    * **V-16** only; signature RRCC flagship engine
+==== Military & Industrial ====
-  * **Military**
+  * **Mules / Trench Carts**
-    * Transport trucks, field generators, armored carriers
+    * **F-4** standard
-    * Early tanks (often using twin smaller Hydras for redundancy)
+    * Tuned for torque and low-speed grunt
-    * Bio-electric drive systems in locomotives and trench rail networks
+  * **Generators**
+    * Early: **V-4**
+    * Post-war and late-war refit: **F-2 / F-4** for compactness
-  * **Civilian**
+  * **Early Tanks & Armored Cars**
-    * RRCC automobiles of all classes
+    * Often twin **V-4** or **V-6** for redundancy
-    * Farm equipment and power tools
+    * Later models adopt **V-8** and **V-12**
-    * Estate-built machinery standardized around Hydra dimensions
-  * **Industrial**
+  * **Bio-Electric Drive Systems**
-    * Factory power units
+    * Twin-engine arrangements (commonly dual V-4 or dual F-6)
-    * Portable and fixed generators
+    * Engines run generators, not drivetrains directly
-    * Marine propulsion on river craft and coastal vessels
+    * Popular because vehicles can “limp home” on one engine
-Hydras became the unofficial benchmark for "standard Emberstonian engineering":
+  * **Marine & Rail**
-simple to service, durable, and forgiving.
+    * **V-12**, **V-16**, and dual-engine configurations
+    * Hydras became the backbone of early river craft and post-war locomotives
