FK-12 Comet with Jabiru 3300 engine
Aerokurier Magazine of June 2006 ( ! ) reported the following relating to Comet D-MOBS.
""Andreras Lehmacher has equipped his FK 12 Comet with the six-cylinder Jabiru 3300 (120hp/88kW). The air sports aircraft office of the Deutscher Aero Club has awarded a Provisional Airworthiness Certification to the re-build, and the flight trials have been running for several weeks. It was clear after the first hours in the air that the Australian engine was a good fit for the agile biplane. It now climbs at 1,500ft/min at 120km/h, and at 2,400 rpm it advances at 155km/h."" with thanks to Aerokurier magazine.
UPDATE 1.9.09 - Andreras Lehmacer has contacted me and confirmed the above news item and also that two other Comets have now modified with Jabiru 3300 engines, these are D-MUZZ and D-MVML - Thanks to Andreras.
