Janowski J-3 Eagle
J-3 Eagle was the third, after Prząśniczka J-1 and J-2 Polonaise amateur single-seat aircraft, designed by Jaroslaw Janowski.
The aircraft of wooden construction featured Wortmann airfoil with flaperons all along the trailing edge, wingtip fuel tanks and composite landing gear legs. The aircraft was powered in succession by a modified Porsche car engine, a Rotax and a BMW R100 engines.The J-3 Eagle (Orzel) was produced using the pod-and-boom pusher arrangement, with a top-mounted engine and conventional landing gear similar to the J-1, and a T-tail stabilator and shoulder-mounted cantilever wings similar to the J-2. The wings used a 19% thick laminar airfoil and could be easily detached for ground transport.
A single example was built by Witold Kalita, J. Janowski and Marian Smith, for whom the aircraft was the intended. The J-3 Eagle was built from sketches, and no blueprints or plans of any sort were ever produced.
When Marian Nowak emigrated from Poland to Canada he took the J-3 with him. He flew the aircraft for 250 trouble-free hours, regularly making 375 mile commutes. However, he decided to take advantage of the detachable wings and transport it by trailer when he exhibited it at the EAA convention at Oshkosh in 1980 as the first amateur construction from the Eastern Bloc.

The Eagle initially flew with a 35 HP converted Porsche automobile engine, but Mr. Nowak also flew it with a Rotax 503, a Rotax 447, a 69 hp BMW motorcycle engine, and finally a water-cooled 3 cylinder Suzuki auto engine. Eventually Mr. Nowak sold the airplane, and the new owner tied it down outdoors where it unfortunately deteriorated beyond airworthy condition. The Transport Canada database listed it as last registered to Wieslaw Pawelkiewicz in April 2002, operating at Burlington, Ontario. It was donated to the Polish Aviation Museum in 2003 by the last owner, Wieslaw Pawełkiewicz of Canada.
