B100i UAV EFI Engine System

B100i EFI Engine System Overview

The newest addition to the Power4Flight portfolio, the B100i EFI twin offers UAV operators improved reliability, power, and configuration flexibility, while addressing the 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 the B29i and 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 Currawong ECU or Power4Flight IntelliJect EFI.
