It consisted of a 90 cc McCulloch chainsaw engine with a direct drive 61 cm (24") wooden prop, producing a quoted 77 lbf (340 N) of thrust the rate of climb was about 150 ft/min (0.76 m/s) and flight duration was limited by the small fuel tank and engine overheating after several minutes. In 1979, a powered backpack called the Motolotnia - White Eagle, designed by Jerzy Kolecki, became available for sale. Soarmaster standard FLPHG power unit Jerzy Kolecki Later, he added wheels to the aircraft and by the end of 1979, there were almost 100 competing companies selling powered ultralights (microlights) but very few were foot-launchable. Then on July 27, 1976, John Moody demonstrated ultralight aviation at the annual EAA fly-in convention in Oshkosh, Wisconsin, with a foot launched McCulloch 101 powered Icarus II in front of thousands of spectators, starting the modern ultralight aviation revolution in the United States. Moody opened the throttle and ran until he lifted from the frozen surface of a lake west of Racine, Wisconsin, and he flew for 30 minutes. On March 15, 1975, John Moody successfully added a 12.5 hp (9 kW) West Bend engine with a 71 cm (28 in) propeller to an UFM Easy Riser biplane hang glider designed by Larry Mauro.

During 1967, Barry Palmer built what is likely the first weight-shift powered trike aircraft. It is now estimated that a modern flexible Rogallo wing hang glider requires at least 6 hp (4 kW) at the prop shaft and about 45 lbf (200 N) of thrust just to maintain level flight. However, the engine was quite underpowered and the craft could not achieve flight. It was powered by a 7 hp (5 kW) West Bend engine and mounted on top of a Rogallo-type flexible wing hang glider the propeller was 3 feet (1 m) in diameter and was made of balsa wood, covered with fiberglass and mounted in pusher configuration.

In 1963, and during his free time, aeronautical engineer Barry Palmer built and experimented with a foot-launched powered hang glider at Bloomfield, Connecticut. Hang gliding record holder Don Mitchell fitted his Mitchell Wing B-10 with a motor, though the pilot still had to use their legs as undercarriage, an arrangement which persisted until he designed the B-10 Mitchell Wing. Differently, a rigid biplane designed also by teenager Taras Kiceniuk Jr., the Icarus II was a foundation for a modification in Larry Mauro's UFM Easy Riser biplane that started to sell in large numbers Larry Mauro would power his tail-less biplane one version was solar powered, called the Solar Riser. The Icarus V flying wing appeared with its tip rudders and swept-back style wing was used as a base for some powered experiments.

Surprisingly, what really launched the powered ultralight aviation movement in the United States was not the Rogallo flexible wing but a whole series of rigid-wing motorized hang gliders.

Inventors from Australia, France and England produced several successful microlight motor gliders in the early 1970s and very few were portable wings. These early experiments went largely unrecorded, even in log books, let alone the press, because the pioneers were uncomfortably aware that the addition of an engine made the craft liable to registration, airworthiness legislation, and the pilot liable to expensive licensing and probably, insurance. For a second time in aviation history, during the 1970s, motorization of simple gliders, especially those portable and foot-launched, became the goal of many inventors and gradually, small wing-mounted power packs were adapted. While powered microlights (ultralights) developed from hang gliding in the late 1970s, they were also a return to the type of low-speed aircraft that were common in the earlier years of aviation, but which were superseded as both civil and military aircraft pursued more speed.
