TIP: Check your total flying weight by
standing on weighing scales with all your
equipment packed into your rucksack.
TIP: Remember that ballast can also
be used to adjust wing loading to the
conditions.
Weight range
Be sure to fly your glider within the certified weight range given in the Technical Specification
section. Due to EPT technology, the Yeti 4 flies well at any wing loading within this weight range. If
you are choosing between 2 sizes, choose your optimum wing loading according to your personal
preferences and the conditions you fly in.
If you prefer dynamic flight behaviour with fast reactions, you should fly at a high wing-
loading, i.e. choose the smaller model. This may be an advantage in strong, tight thermals.
The dynamics are reduced in the middle and lower part of the weight range. Flight behaviour
becomes more straightforward and many pilots fly with this wing loading because they find it
easier to centre in thermals, especially weaker and wider thermals. If these features appeal to
you, you should fly with a lower wing-loading and choose the larger model.
The Yeti 4 reacts to weight changes only by slightly increasing or reducing trim speed, with
little noticeable effect on glide performance. You can therefore choose the size completely
according to your own flying style.
Extended weight range
The Yeti 4 has an extended weight range. This enables suitably experienced pilots to enjoy
dynamic flying in stronger conditions or to reduce weight by carrying a smaller-sized glider. The
Yeti 4 is certified EN A in both normal and extended weight ranges.
Overload
The EN 926-2:2013 describes the weight measurement with: “All weights are subject to
an acceptable tolerance of ± 2kg”. Therefore a slight overload of the wing would be within EN
