The 4103 is an air-cooled, rotary valve controlled 2-stroke boxer engine with electronic fuel injection. It utilizes advanced closed loop control to optimize performance for extreme environmental conditions (hot/cold/altitude).
based on the worldwide well known 4102 engine which to date has flow more than 20,000 missions in theatre, the new 4103 engine has been updated with the latest engine technology to create a new off the shelf propulsion system which meets the demanding requirements of the unmanned aerial vehicle market. The engine features automatic altitude and temperature compensation enabling reliable start and operation in a wide operating range. Temperature: -40 to +50° C (-40 to +122° F). Altitude: 0 - 6000m (0 - 20,000 ft.).
