Description
DA 215 EFI UAV Engine is fit 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 no-fuss starting.
A single 3 cell Lipo battery of 1500mah or larger capacity, powers the ECM. Peak current draw is only 2 A.
Alternator System Options
CHPS-MX 1500 W Power Management Unit
The Currawong Cortex Hybrid Power System (CHPS-MX) pairs with the alternator to supply up to 1.5 kW on a 50 V rail, plus programmable rails of 12-28 V at 250 W, 5-12 V at 100 W and 12-18 V at 75 W.
Its hybrid design can deliver power from the generator, the battery or both at once.

500W Starter Alternator
This 3 phase brushless alternator drives direct on the engine crankshaft. The stator mounts to the crankshaft casing. The rotor spins on the crankshaft. The starter alternator weighs 1.4 kg (3.1 lb).
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 Lilon, LiPo, LifePO4, SLA, NiCad, NiMH, and Lead Acid Battery.
Custom Alternators
Custom options are available upon request.

System Testing
The system is tested to numerous standards- from sea level to 10,000 foot altitude, and the engine is rated for ambient temperatures from 5°F to 150°F (-15°C to 66°C). HFE International also offers engine dyno testing for customer engines and maintenance contracts for fleets in service.
Frequently Asked Questions About the DA 215 EFI UAV Engine
The DA 215 EFI produces 13.6 hp (10.2 kW) continuous at 6,000 RPM and up to 15.3 hp (11.4 kW) at 7,500 RPM, with peak torque of 16.9 Nm (12.4 lb-ft) at 4,500 RPM, measured with the stock muffler. It runs from 2,000 to 8,000 RPM, with average brake specific fuel consumption of 524 g/kWh (0.86 lb/hp-hr).
The standard DA-215 is a carbureted engine built for radio-controlled aircraft. HFE International converts it to electronic fuel injection for unmanned aircraft, adding an engine control module, fuel pump and ignition tuned for UAV duty. The EFI system corrects for altitude and cylinder head temperature, protects against overheating, logs data on board and reports telemetry over CAN bus and RS-232. The specifications on this page are for the HFE EFI version.
Any grade of pump gasoline, mixed 40:1 with Red Line two-stroke oil. There is no heavy-fuel option for the DA 215 at this time. For JP-8 or Jet A operation, HFE International offers custom heavy-fuel design and consultation. Contact HFE to discuss your requirements.
A 3-cell (3S) or larger LiPo battery. The ECM draws up to 2 A at peak, and each 1,000 mAh of battery capacity gives roughly one hour of running.
Yes. The optional 500 W starter alternator drives directly on the crankshaft and pairs with a 500 W power management unit that includes a starter controller, so the engine can start remotely. The PMU supplies three lines: 24 to 28 VDC at 12.5 A (350 W max), 12 to 15 VDC at 9 A (108 W) and 4.8 to 8 VDC at 8 A (42 W). The starter alternator weighs 1.4 kg (3.1 lb). For higher loads, the CHPS-MX power management unit supplies up to 1.5 kW on a 50 V rail. Custom alternators are available on request.
Yes, as an option. The Mil Spec EFI package uses Currawong premium EFI hardware, is rated from -10°F to 120°F (-23°C to 49°C) and runs 400 hours between overhauls. The Currawong ECM is tested to MIL-STD-810 and adds cold-temperature operation to -40°C (-40°F), EMI and ESD filtering and RF shielding. Contact HFE International for configuration and pricing.
