Information on the website is not easy to find today, but there is a brochure on this page: http://www.fk-servicecenter.com/navid.28/aktuelles.htm
The "take-off weight" is listed at 520 Kg (1144 pounds). The performance with it's 80 HP Walter Mikron looks rather good. The FK131 may be operated under aerobatic, or UL rules according to the brochure (or at least my understanding of the brochure)

B&F announces the FK131
German aircraft manufacturers B&F Technik Speyer have just announced the latest project in their “FK Classic Line”. A series of initially only 10 aircraft replicas of the famous Bücker131 Jungmann biplane of the Thirties and Fourties era of the twentieth century will be produced in co-operation with the Czech company Podesva Air.This will be a relatively exact replica of the Jungmann's "A" version with almost identical dimensions. From 1934 through 1935 the first series of the Jungmann aircraft model was equipped by Bücker with an 80 hp Hirth engine. This power plant's technical successor, the Walter Micron IIIC is still being built in the Czech Republic to this day, albeit in a technically modified form, but as an aviation certified, 2.7 litre in-line four cylinder aircraft engine. By selecting this engine for their Jungmann replica, B&F have made sure that, both the sound as well as the performance of the FK131 will be very closely similar to the original Jungmann.
The FK 131 can be certified either as a kitplane within the Experimental category, or as an ultralight aircraft! This is hardly surprising since the A-series of Jungmann aircraft were originally made by Bücker with an empty weight of just 340 kg. With its slightly modified construction of the empennage, today's lighter engine, and a number of further improvements B&F have set the ambitious goal of meeting the requirements for a certification of the FK131 in the ultralight category. In spite of the low weight of the aircraft, Peter Funk, graduate engineer and owner of B&F has designed the FK131 in accordance with the requirements for simple aerobatic aircraft.
In contrast with all other FK aircraft models that are being licence-built and marketed by the Polish company FK-Lightplanes since 2010, the limited series of FK131 aircraft will be made and sold directly by B&F to afford a favourable price. The first three aircraft will thus be available at a special price of approximately 76,000.00 Euros including 19% VAT. The remaining aircraft in the limited edition will then be sold at circa 85,000.00 Euros per aircraft.
