The Schwing 88 is a high performance sport glider that has been designed with a performance envelope that closely mimics the efficiency and speed of contemporary competition gliders.
The Swing 88 was designed by James Hammond who is one of the most successful glider designers in the world today. There probably isn’t a slope or hill where we slope flyers go that hasn’t been flown by one of his designs! And for good reason, his planes just fly so well. The Schwing has gone through a lengthy design program that has resulted in a re-design of almost every component, including wind tunnel testing of new wing sections.
So... How does it look ?
The finish is clean and clear, lines are crisp and colors deep. The level of completion is high, wipers as well as the brass control horns are installed and the servo bays are heavily reinforced with carbon. The openings for the wings electrical connections (green MPX connector size) have been made, and the aluminium incidence pins are installed.
Lets take a look at the specifics:
The sections are the latest development from James’s highly successful original airfoil designs and to quote James: “It took a while to get there and a huge amount of testing, because I wanted a series of sections that would make slow speed handling even slower, and high speed capability even faster.”
Designed to reflex as well as to droop, the airfoils used on the wing were specifically conceived with all round sport flying in mind and hence are unusually aerobatic too! The descending thickness, optimally cambered sections will let you go from really slow landing speeds with the flaps down to blistering passes with a little reflex, yet the plane will thermal away in light air in conditions you would not normally try, well, most of us anyway! The optimization for the rear area of the wing allow a smoother transition when in camber or reflex, try aerobatics with elevator and the whole trailing edge of the wing linked with a little reflex as well as camber and you will be amazed. Those that want to get every last bit of performance will find that permanently coupling with the elevator is actually a very efficient way to fly this plane; some call it a ‘live wing’. It was by design! Large ailerons, large flaps and a semi elliptical wing planform each add to the overall performance of the plane. Spars are impressively huge for this wing which is always a telling indication of what this wing is designed to do! Constructed with copious amounts of carbon and glass, hollow molded around a balsa core, these wings are stiff, torsionally as well as laterally.
Like all of the Aeroteam airframes, the Schwing 88 has a large joiner. Massive is the only way to describe this part. It’s just over 35 x 12mm and can handle acro and light DS
Aeroteam Sine Wave Spar:
Used in several military aircraft, the Sine Wave Spar has been adapted for the first time to a model sailplane wing, and has frankly amazed us with its low weight, and ultra high strength. Unlike a conventional spar the Sine Wave Spar adds terrific torsional strength and yet actually weighs considerably less than the older non-optimized spar. Now to be used in all Aeroteam sailplanes, the Sine Wave Spar is a lighter and far stronger upgrade that raises the technology level yet another notch and could be a game changer in model sailplane technology.
The beautifully contoured fuse is strong, light, stiff and slim! Carbon reinforcement gives all important stiffness in the boom. The electronics area is 2.4 GHz friendly with access to the radio and ballast through a conventional slide-on hatch type canopy. The long nose area accentuates the pretty lines but also provides plenty of space to easily balance the model without resorting to shoehorning lead in every nook and cranny! The pushrods are of excellent quality and are pre-installed in the fuse.
Again the airfoil was specifically designed for the tail plane and this time for maximum control response with minimum deflection. At 10%, the tail plane section is thicker than is the norm but the infinitesimal increase in drag is easily offset by the increased control response for less deflection. The tails are set 0-0 degrees to the wing. To further increase the efficiency, pitch control is accomplished by using an elevator. No wobbly all moving tail and the elevator is driven by either an optional ball raced bell crank from a servo in the fuse, or where ultimate control is required, a servo can be placed in a hatch through the fin to give solid elevator control. We felt the hatch was important, as any bell crank mechanism will need to be maintained at some point. The tails remain removable for convenient transport or storage.
The Schwing can carry 8, 19mm diameter x 35mm brass slugs in the fuse and 2 long round brass bars in the wings, a total of just under 900g. We found it just loves the weight! It wasn’t long ago that a 3m competition plane carried that much weight, but things have moved on!
