With the Fizz, we aim at the top place among the high performance gliders with king-post. The Fizz sets new standards with its thermalling qualities as well as its performance in faster glide mode and in cross-country flying. In 2017, the Fizz SE (SE = special edition) is available, a further refined version of the Fizz with a top-of-the-line configuration (see below). Of course, the improved finetuning of frame and sail is implemented also in the serial version of the Fizz 2017.
Today, most pilots prefer light, uncomplicated but high performance gliders. Heavy topless competition gliders tend to take the fun out of flying, and the price for these sophisticated machines is often not warranted in view of the performance gain. In 2006, our response was the kingposted high performance glider Kite. Its light handling and very good thermalling characteristics were (and still are) a source of pleasure for many pilots. The Fizz continues this development line with improved flight performance over the entire speed range, in particular at higher speeds.
The sail determines the performance of a glider. With form stable, expensive sail materials, a new wing with a thin airfoil was created, which is perfectly adapted to the flexibility of the leading edge tube assemblies. Winglets are at the sail ends. The wing has a shorter chord at the keel than the Kite, and a double surface of 90%. The leading edge tubes are stiffer at the quarter-span. The frame and cables are safe and tested components. Everything is easy and simple to inspect, damage can be repaired economically.
After delivering numerous Fizz gliders, it’s time for an evaluation, based (as always) on the feedback we receive from our customers. At this occasion, a heartfelt thanks to all of you!
Without exaggeration, we can say that our customers’ feedback has been unanimously positive. This is a bit of a (pleasant) surprise, as the reports come from very different pilots. Among the Fizz pilots, there are “young guns” flying their first high-performance glider, experienced soaring and cross-country pilots (both male and female) as well as “old eagles” beyond the age of professional retirement. They often emphasize the precise information the glider gives about the surrounding air, the benign stalling characteristics, the directional stability and well-balanced turning and the good landing properties. Nonetheless, it has to be kept in mind that the Fizz is not an intermediate, but a high-performance hang glider which requires precise and anticipatory flying. Due to the flat glide angle, the landing approach has to be set up more carefully than with an intermediate glider.
As for flight performance, we are of course fully aware that much depends on the pilot. Nevertheless: All reports mention that the Fizz is an extremely good climber. Whether in weakest thermals or in turbulent air – the Fizz enables the pilot to make the most of the weather conditions. A low sink rate and a good climbing performance, combined with an easy, well-coordinated handling, often make the difference between staying up or going down, and we hear time and again that Fizz pilots “stayed up”. When it comes to gliding against the wind, there are often wing-to-wing comparisons, also with topless high-performance gliders. And in these cases there has been quite some astonishment on both sides about how “close” the Fizz is to those expensive machines. We have no doubt that the Fizz is, also in terms of flight performance, among the very best kingposted gliders; and all this with a simple and robust construction without any load-bearing glass or carbon-fiber parts.
The Fizz is our best design so far. We are convinced that the Fizz matches the expectations of demanding recreational and cross-country pilots.
The Fizz SE is the result of our constant effort to optimize our high-performance glider. A light, transparent double surface made from ODL, extra-stiff 10mm carbon battens and an improved finetuning of frame and sail result in higher aerodynamic stability, better handling and further improved glide performance.
Thanks to many clever construction details the set up and break down of this glider is exemplary simple, and without effort.
The Fizz has the classic and time tested kingpost construction, without luff-lines, but with sprogs inside the double sail. With the VG detensioned, the side wires (flying wires) are almost tight and spring loaded. This means the steel springs act as shock absorbers in turbulence at sudden loading and unloading of the flying wires, load extremes are dampened and pilot comfort is higher. The Fizz packs short to 13.5 ft and weighs 69 lbs. The slightly higher weight results from a stiffer leading edge and the greater hook-in weight of 260 lbs. and take-off weight of 328 lbs; this allows all typical engine and electrical start systems to be used with the Fizz.
All wing tubes are 50‐52 mm, the crossbar is 60‐62 mm, the keel is 50‐48 mm Alum. 7075 , 0.9 mm thickness. Kingpost and down tubes are of the low drag Bautek profile, which is a little heavier than normal for these components but can tolerate a bit more abuse.
The hang point is up on the kingpost. The stainless steel cables are smooth without plastic coating for lower drag. Lower side cables and top rigging are 2.5 mm for extra strength and safety. A profiled Aluminum speedbar, which allows for split wheels to be mounted, is optional. From 2014, new CNC-milled brackets are delivered, adding to the premium-quality of the glider.
The Fizz too has radial wingtips, no fiberglass “sticks” to bend. This saves not only energy during set‐up and break-down, but also protects the sail ends from wear and tear, since the sail can be rolled up without fold at the end. Winglets with Velcro attachment close the wing at the outside. Improved fibreglass winglets are now part of the standard configuration. The mainsail is an all Mylar sail, made out of transparent ODL‐Laminate, the leading edge can be PX 10 or ODL. The double sail material is 180 g heavy polyester fabric in standard available colors.
The Fizz is neutral on the shoulders and easy to control on launch. The integral spring system reduces slack in the the side wires to a minimum when the VG is off; so there is no problem to set proper attitudes and balance for the start. Pilots, who like “tight” side wires for launching, can do so with ca. 3 ft pulled out on the VG.
The Fizz has a very efficient variable geometry (VG) which can increase the sail tension in flight. With loose VG the wing has more twist (remember the “Twister”), is neutral in turns and has a light, agile handling. For the first flight, half tensioned VG is recommended to avoid over controlling. Even with VG full on the Fizz can still be controlled around the vertical axle. In that configuration the wing has little twist and the best glide ratio. The Fizz should preferably be steered by short control impulses, especially at higher speeds; e.g. when winch- or aero‐towed. For a futher increase of directional stability (in particular for winch or aerotowing), an optinal tail fin can be mounted to the keel. The airstream separation (stall) is smooth and is easily controlled, so that in a thermal the Fizz can be flown very slowly with optimal climb rate.
The Fizz lands easily. It glides a long way in ground effect, especially if accelerated before, but will slow down to very slow speed; at push out time (flare time) the nose comes up by itself, increases the angle of attack and drag and stand up landings are the norm already at a light breeze.
We earned our good reputation for service over a span of more than 30 years. With a competent and trust worthy team we are able to perform all repairs and inspections timely and economically.
