F O Engineering has a strong background in designing and developing products and systems for the Aerospace industry. Products range from simple analog electromechanical actuator controls to high performance, redundant digital based system controls. All products are designed to withstand the harsh environments typical of Aerospace ground and flight applications, such as temperature, vibration, power conditions, EMI/EMC, etc.


F O Engineering’s extensive experience in system design and control electronics allows a one-stop-shop for electromechanical systems from concept through design, integration and production. Whether it’s a self-contained miniature motor controller or a large and complex system design, F O Engineering can help solve your problems.
