The 350r is a variant of the 300 series developed by Origin Jumpworks. Designed by Andreas Lang, a limited run of prototypes were initially created and distributed to racing teams to promote the use of the 300i as a high performance platform. Met with unexpected success, Origin began constructing them for a wider customer base, though still in much smaller manufacturer runs than the other 300 series subtypes. The design is easily identifiable compared to other 300i variants because it has twin main thrusters instead of a single drive plume.
