System Overview
The B100i EFI twin offers UAV operators improved reliability and power, while addressing shortcomings commonly found in 2-stroke singles. The B100i incorporates the latest engine technologies from Power4Flight, Cobra-Aero and Currawong engineering using the tried-and-true DA100 engine core from Desert Aircraft.
The engine package includes
- Cobra-Aero induction system
- Currawong self-priming fuel pump and fuel pressure accumulator
- CDI modules
- MAT and dual CHT sensors
- IntelliJect ECU and wire harness
- Starter/Generator
- Cooling ducts with active doors
- Focal isolation mount
