Most Recent Projects


Jim has recently  finished development of the Pioneer III, a tailless, all composite, lightweight aircraft being 100lbs lighter than the wood wing Pioneer II.  The Pioneer III enjoys a 20% reduction in wing drag resulting in an excellent sailplane that can perform exceptionally well under weak lift conditions.  On its first attempt to soar under marginal thermal conditions, the Pioneer III made a 5 hour flight.  On its second flight, it flew a 60 mile round trip, being careful to stay within the limits of the FAA flight test area.  

Collaborative Projects


In 1992, he teamed up with John Roncz as principal designers for the company Group Genesis with developed the aircraft Genesis I.  Two years later the Genesis I became the first successful semi-flying wing aircraft ever built.  Twenty-six of the Genesis 2's were built.  In 1997,  Jim finally found the high quality Carbon Rod that he had been searching for that could increase the reliability of the wing spar and subsequently reduce the overall weight.  Later that year, Jim and the Genesis team built the Genesis II, the first aircraft to use Graphlite Carbon Rod in a production Aircraft.  

A Pioneer in Aviation


At the age of 37, Jim built the Pioneer II with the intent to address the needs of the amateur glider builder. The Pioneer II had a more simplified structure than the Pioneer I and had increased performance.  Jim continued to experiment with composites with the goal to completely eliminate wood from the structure. By theage of 39, Jim completed his first 'almost' fully composite aircraft, the Monarch.  Over the next 20 years, Jim shifted his focus to designing high performance, low drag airfoils to achieve lower sink rate and increase the speed range of the aircraft.

Experimental Aircraft


At the young age of 19, Jim built the XM-1, his first flying wing design inspired by the works of Chrales Fauvel and Al Backstrom.  Jim found the scale models of the unswept tailless wing concept to be superior in performance and stability when compared to conventional designs.  The initial design of XM-1 'Flying Plank', and Pioneer I were of wood and composite construction.

HISTORY OF THE MARSKE FLYING WING

About Jim Marske

 

Jim has been in Aviation all his life.  From the age of 5, he was passionate about building and flying.  In his early years he built a variety of different model airplanes from simple rubber powered designs to more advanced gasoline powered models.  As a teenager, he progressed from model building to restoring full size aircraft and had developed a strong interest in soaring and flying wings.


 GRAPHLITE

Carbon Rod 

 

Graphlite carbon redefines the performance of aircraft wing spars.  No other conventional carbon can claim the Graphlite combination of superior strength and lighter weight.
