Design
    
The SB-10 is a cantilever shoulder-wing monoplane with a steel-tube structure fuselage and it used the wings from the earlier SB-9 Stratus.[1] The two crew sit in tandem in an enclosed cockpit with a Plexiglas canopy, and it is fitted with dual instrumentation.[1] The landing gear is a sprung retractable monowheel with a tail bumper.[1] The wingtips are interchangeable and two types can be fitted to give a 26m or 29m span.[1] The wing center section, its main spar and wing shells of 8m length were built using carbon fiber, a first in civil aircraft structure manufacturing.
