DA70

The INF Inject DA70 is a lightweight 70cc UAV engine built with precision CNC-machined 6061 and 7071 aluminum. Featuring INF Inject’s proprietary electronic fuel injection (EFI) system, it delivers up to 65% better fuel efficiency along with automatic altitude compensation and fuel injection overheat protection. The engine uses a single power supply for the entire system and supports both 24V and 48.5V starter/alternators for onboard power generation.

Designed for easy integration, the DA70 includes automatic throttle control, positive locking commercial connectors, and seamless autopilot compatibility. Each engine is calibrated and test-run before shipment, with full telemetry via TTL 9600 baud and onboard SD card logging (or a no-logging option). Non-branded configurations are also available to support OEM requirements.
