The all-metal The Yakovlev Yak-52 is powered by a 268 kW (360 hp) Vedeneyev M14P nine-cylinder radial engine. The aircraft has inverted fuel and oil systems permitting inverted flight for as long as two minutes. The engine drives a two-bladed counter-clockwise rotating, variable pitch, wood and fiberglass laminate propeller. At 998 kg empty weight, the Yak-52 is responsive and very capable as an aerobatic aircraft. Yet it is also easy to fly and land. It has been used in international aerobatic competition up to the Advanced level. It is stressed to +7 and Ð5 Gs, rolls (to the right) at 180 degrees/second and is capable of every manoeuvre in the Aresti catalog. -[Wikipedia]
