04/30/2011. Remarks by Walter van Tilborg: "The J6 Fregata was a design of Jaroslaw Janowski of Lodz in co-operation with Wojciech Jeriorski. The J6 configuration was very similar to Janowski's earlier designs, but it featured larger wings to allow operation as a motor glider and was available for amateur construction. The aircraft was registered SP-P046 and piloted by Jerzy Kedzierski it first flew on December 15 1993, powered by a 39 hp Mosler
CB-40 engine.

Re-engined with a 52 hp J&AS 3PZ-800 three-cylinder engine (modified Honda BF45 marine engine), it was first flown on July 19, 1995. It was lost in an accident a year late, July 16, 1996, by which time the second prototype was flown, registered SP-P049. This featured a more conventional two wheel landing gear.

From 1998 onwards, it was marketed via J & AS Aero Design in Poland and a small number of aircraft were completed, reportedly five: both prototypes, c/n 003 (SP-8056), c/n 004, and c/n 005 (registered in the USA as N105JJ). In 2005 all J6 rights and some components were acquired by BAE Systems for use in the development of its HERTI (High Endurance Rapid Technology Insertion) long-range reconnaissance UAV (Unmanned Air Vehicle)."
