Core offering

HFE International designs and manufactures small propulsion systems, engines, and accessories for unmanned aerial vehicles and small aircraft. Its portfolio centers on the patented GenPod® modular engine system (5–15 hp), DA EFI commercial engines, and Mil-Spec EFI military-grade engines, alongside authorized North American distribution of AIE UK Wankel rotary engines. The company complements its hardware with engineering services including engine dynamometer testing, fuel injection system integration, maintenance contracts, mobile engine testing, and thermal chamber qualification services.

Product overview

HFE International is a small high-tech company based in Tucson, Arizona, specializing in reliable small engines for UAV, unmanned, and small aircraft applications. The company offers a portfolio of propulsion solutions centered around three main engine product lines: GenPod® Engines (integrated systems with built-in generator, power management, EFI, fuel pump, ignition and vibration isolation in sizes 5-15 hp), DA EFI Engines (commercial-grade engines for fixed-wing and multi-rotor platforms with 10°F to 130°F operating range), and Mil Spec EFI Engines (military-grade systems using Currawong components tested to Mil-Std 810 for operation down to -40°F). The company also resells AIE UK Wankel rotary engines (40S, 80S, 225CS) featuring patented SPARCS cooling technology. Supporting the engine portfolio is a comprehensive accessories line including Volz servos, Currawong Velocity ESCs, fuel systems, air filters, and electronic components. HFE complements its product sales with services including engine dyno testing, fuel injection system services, maintenance contracts, mobile engine testing, and thermal chamber testing. The company holds ISO 9001:2015 and IPC 610/620 certifications.
