The DA 150 EFI UAV Engine is a 150 cc engine featuring an electronic fuel injection system that delivers the correct fuel mixture and spark timing for stable operation, including high-performance 3D flights. The engine control module is powered by a single 3-cell LiPo battery of 1500 mAh or greater capacity, with a maximum draw of 12 W (1 A) at full throttle. Designed for professional UAV use, the system supports efficient operation across a broad RPM range.
A 500 W starter-alternator option directly drives from the crankshaft, with the stator mounted to the crankshaft casing and the rotor spinning on the crankshaft. This can be paired with a 500 W power management unit (PMU) with integrated starter controller for remote start capability. The PMU provides three configurable outputs: 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. The system is compatible with LiIon, LiPo, LiFePO4, SLA, NiCad, NiMH, and lead acid batteries, and custom alternator solutions are available on request.
