Excerpt: The Praga E-210 was a four seat, twin engined touring aircraft built in Czechoslovakia in the late 1930s. It had an unusual pusher configuration .

It was unusual in adopting a pusher configuration, with two engines close to the fuselage driving small propellers. Its layout was thus much like that of the Carden-Baynes Bee, its almost exact contemporary though a much smaller aircraft. The wing of the E-210 was made in a single piece, a wooden structure built around two spars and plywood covered. The leading edge was significantly swept, but the trailing edge was straight. The ailerons were steel framed and fabric covered. Between them and the engines were Schrenk type landing flaps. The 85/95 hp (63/71 kW) Walter Minor four cylinder inverted in line engines were cantilevered from the rear spar on steel frames, with fairings both above and below the wings. The flat sided fuselage was built on a steel tube framework, narrowing to the rear. The r... More: http://booksllc.net/?id=25643271
