The Spartan Edition lowers it without touching what matters: the engine inside is exactly the same INFERNO Gen 2 as the Premium.\u003c\/p\u003e\n\u003cp\u003eWhat changes is how you set it up. The \u003cstrong\u003eSpartan Electronics board combines the trigger board and FCU in one unit\u003c\/strong\u003e, and Wolverine tune it through the trigger itself — a system they call \u003cstrong\u003eLive Fire Tuning\u003c\/strong\u003e. You hold the trigger while connecting the battery to enter programming mode, then step through settings by firing into a chronograph. Dwell steps down with each pull until you see FPS drop, you double-tap back up one, and you are done. It takes under a minute and needs no app, cable or computer.\u003c\/p\u003e\n\u003cp\u003eUnderneath the electronics, this is the same Gen 2 platform Wolverine built to solve what the industry calls the open-bolt problem. Open-bolt engines waste no air and tune easily but make the hop awkward; closed-bolt systems reverse that trade. By running an \u003cstrong\u003eindependent poppet and nozzle from a single solenoid\u003c\/strong\u003e, the Gen 2 sidesteps the choice — and gains around \u003cstrong\u003e10 to 15 per cent efficiency\u003c\/strong\u003e over the previous generation in the process. More shots per fill, and a hop that stays where you set it.\u003c\/p\u003e\n\u003cp\u003eThe presets cover what most players actually change. \u003cstrong\u003eThree fire mode options\u003c\/strong\u003e — semi\/full-auto, semi\/three-round-burst, or semi\/semi. \u003cstrong\u003eEight rate-of-fire presets from 10 to 33 RPS.\u003c\/strong\u003e \u003cstrong\u003eTwelve dwell presets.\u003c\/strong\u003e Simple, robust, and with nothing to go wrong in the middle of a game.\u003c\/p\u003e\n\u003cp\u003eIt drops into a V2 M4 gearbox with no modification, leaving your receiver and furniture untouched.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eDrop-in HPA engine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGearbox\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eV2, M4 cylinder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGeneration\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eINFERNO Gen 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eDesign\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSingle solenoid, independent poppet and nozzle — hybrid open\/closed bolt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eElectronics\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSpartan board — integrated trigger board and FCU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eTuning\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eLive Fire Tuning, set through the trigger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eFire modes\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e3 presets: semi\/full-auto, semi\/3-round burst, semi\/semi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eRate of fire\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e8 presets, 10 to 33 RPS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eDwell\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e12 presets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eEfficiency\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eApproximately 10-15% improvement over previous Wolverine systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eInstallation\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eDrop-in, no gearbox modification required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWolverine Airsoft, USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eGood to know before you buy\u003c\/h2\u003e\u003cp\u003eThe engine is identical to the Premium Edition — the difference is entirely in the electronics.
