B100i UAV EFI Engine System

Description

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. All the benefits of B50i remain, plus the following key features:

  • Power Density: 40% higher power/weight than B50i
  • Low Vibration: Opposed twin layout for greatly reduced primary vibration
  • Reliability: Four-bearing crankshaft and high rod/stroke ratio for reduced stress
  • Flexibility: Dedicated PTO, dual spark option, side induction, and stock or quiet mufflers.
  • Compatibility: Readily integrates with flight control systems; available with CE367 ECU or Power4Flight IntelliJect EFI.
