DA 100 EFI UAV Engine comes with state of the art electronic fuel injection.

A special magnet configuration mounts in the prop hub and allows the prop to easily flip for a no-fuss start.

A single 3 cell Lipo battery of 1500mah or larger capacity powers the ECM. At full throttle, the total power draw is only 12 watts (1 amp).

Alternator System Options

400W Starter Alternator

This 3 phase brushless alternator direct drives on the engine crankshaft. The stator mounts to the crankshaft casing. The rotor spins on the crankshaft.

The system can be paired with a 500 W Power Management Unit, with an integrated starter controller, allowing the engine to start remotely. The PMU provides three lines with a chosen voltage in the range: 24 – 28 VDC at 12.5A or 350W max, 12 – 15 VDC at 9A or 108W, and 4.8 – 8 VDC at 8A or 42W.

Configurable with LiIon, LiPo, LifePO4, SLA, NiCad, NiMH, and Lead Acid Battery.
