FLS Microjet (BD-5J)

FLS Microjet (Flight-Line-Series) is an improved version of the BD-5J. It has been designed and marketed as a kit by BD-Micro Technologies (BMT). Most of the components conform to the original Bede specifications, but many improvements have been made by BMT.

The first Microjet built from a FLS kit, and having flown, was Justin LEWIS's N60LC (Oklahoma City, USA). The construction was conducted between 2003 and 2010. Due to the complexity of the project, it was continuously monitored by BMT. The first flight, Justin at the controls, took place on January 27, 2011. The flight tests were completed on May 5, 2011. Justin has regularly presented his plane in aerial meetings (in the USA) since the summer of 2011.

The integration of the turbojet engine was specially designed for the FLS. It uses the PBS TJ-100 in its 265/280 lb of thrust version. This compact, lightweight turbojet, incorporating a modern FADEC, offers a good power to weight ratio.

This integration, called the Quantum Turbine Powerplant System, was done with the help of PBS, which led to the development of several engine safety features. PBS TJ-100 seems to be the main alternative for the replacement of old Microturbo TRS-18.
