4201

42 Series

The 42 Series air cooled two-stroke engines utilise advanced closed-loop control, optimising performance for extreme environmental conditions.

Based on the well-known S1211 and S1212 engines – which have been proven in theatre – the new 42 Series have been updated with the latest in engine technology providing a top shelf propulsion system that meets the demanding requirements of the unmanned aerial vehicle (UAV) market.

This engine series features automatic altitude and temperature compensation allowing reliable start and operation in a wide operating range.

  • 2-Stroke
  • Air Cooled
  • State-of-the-art engine technology
  • Best performance for unmanned aerial vehicles (UAV)
