Schneider Boomerang ES-60 Arrow / Super Arrow



The ES 60B Super Arrow was developed from the Standard Class single-seater, the ES 60 Series 2 Boomerang, and the ES 59 Arrow; the Boomerang was designed in 1964 for competition flying, and the first of two prototypes made its first flight on 28 November 1964, followed by the second on 24 December that year. These were followed by six ES 60 Series 1s built in 1966, and 28 ES 60 Series 2s completed in 1967 and 1968, plus a few more built since then, this differing from the Series 1 in having the height of the plywood-covered fin reduced by 3in, and a lengthened sideways-opening Perspex cockpit canopy; later production Series 2s had the nose lengthened by 2.5 in, a larger monowheel and an adjustable seat back for the pilot. The Boomerang soon made its mark in contest flying, and for a time held all the Australian national speed records over 100km, 200km and 300km triangular closed circuits, at speeds of 54mph, 55mph and 59mph respectively.
The Boomerang was succeeded by the ES 60B Super Arrow, also designed for competition flying, which first flew in prototype form on 22 September 1969 and which was awarded a C of A on 31 October that year. It was the same as the ES 60 Series 2 Boomerang but had the conventional tail unit of the ES 59 Arrow with an unswept, fixed tailplane mounted at the base of, and forward of the fin instead of the Boomerang's swept-back 'all flying' tailplane, the halves of which were mounted separately on the fin about one-third of the way up, being secured by automatic spring-loaded bayonet couplings. In both cases the tailplanes were cantilever wooden structures with plywood and fabric covering, that of the Boomerang having a trim tab that also acted as an anti-balance tab, the fin being ply-covered and the wooden rudder fabric covered. Apart from their tailplanes, the two types are of the same wooden construction, with a cantilever highset one-piece wing with a laminated beech spar at the 50% chord line, a moulded plastic leading edge and birch ply covering back to 60% chord; wing tip 'bumpers' are fitted. There are no flaps, but metal scissor-type air brakes with epoxy-bonded wooden flanges are fitted at 55% chord; the wooden ailerons are plywood-covered. The ply-covered semimonocoque fuselage has glassfibre fairings, and the non-retractable monowheel has an expanding shoe brake; unlike the ES 59 Arrow, there is no nose skid, but there is a spring steel tailskid. The pilot sits under a sideways-opening jettisonable Perspex canopy, and has adjustable rudder pedals and seat back; the customer specifies what instruments are fitted, and oxygen and radio can also be carried.
