The DA 215 EFI UAV Engine from HFE International is equipped with an electronic fuel injection system for accurate fuel delivery and ignition control. A magnet assembly in the prop hub allows quick manual starting, and the engine control module operates from a single 3-cell LiPo battery of 1500 mAh or greater capacity. At full throttle, power draw is 12 W (1 A). The DA 215 EFI is designed for consistent performance in a variety of UAV operating environments.
Alternator options include a 200 W power management unit (PMU) that provides regulated outputs of 12–15 VDC at up to 200 W and 4.8–7 VDC at up to 42 W, with an optional 24 V configuration. A 500 W starter-alternator is also available, driving directly from the crankshaft and pairable with a 500 W PMU with integrated starter controller for remote starting. This PMU provides outputs of 24–28 VDC at up to 350 W, 12–15 VDC at up to 108 W, and 4.8–8 VDC at up to 42 W. All systems are compatible with LiIon, LiPo, LiFePO4, SLA, NiCad, NiMH, and lead acid batteries. Custom alternator configurations can be specified upon request.
