The perfect balance!

We are learning more and more. We are learning with every prototype wing we build and analyse. We are learning about performance wings and safety on the bottom of the range. More and more we are able to combine performance and safety to a new level of balance: here is the SONATA 2!

SONATA 2 Technical Features

The SONATA 2 is not only the small sister of the SYMPHONIA 2. Because of the higher safety level it can afford a very big extended weight range to offer the pilot or the school more options. The covered lines make it easier for not so experienced pilots. The take off behaviour as well as the roll stability are excellent: a MUST HAVE for a modern wing in that class.

The feedback from active schooling with the SONATA 2 is confirming, that we reached our goal: takoff is very easy, roll stability excellent and most noticeable: the performance stands out from all others.

SONATA 2 Designer’s Note

To optimize wings in that mid A class is not an easy task. The structural stiffness is a challenge. More wing curve is not the way to go as it results in less roll compensation. So we had to invest in the internals and the line angles. In contrast to the first generation of SONATA, the SONATA 2 has 3 main lines and plenty of diagonal fingers. A very high complexity for this cost critical class of “school wings”. But the result of this effort is opening the door for not only being a “school wing”. The SONATA 2 has a delightful handling and an outstanding performance, which pleasures advanced pilots long after their first flights on the training hill.

SONATA 2 Testing

As always, our test pilots put the SONATA 2 through its paces. It pays off: safety trainers value our gliders for their good behavior during extreme manoeuvres. The same applies to the SONATA 2: it is a pleasure to test it: very unspectacular in its reactions!

SONATA 2 Weight Ranges

The take off weight on the scale includes pilot + equipment + wing.
For schooling and thermal flying it is recommended to stay in the normal range.
For high wind conditions the extended range offers more speed, energy and possibilities.

SONATA 2 risers

The SONATA 2 is delivered with the semilight riser R10.
As for every PHI wing you can choose your riser at order free of charge.

What is new? What is the difference between the SONATA 1 and the SONATA 2?

The Cell number (40) and the ground shape (flat aspect ratio) are the same. The flat area is the same, but the canopy is more flat: the projected area is bigger. We kept the naming of the first generation for a better orientation, even the SONATA 2 24 has slightly more than 24qm projected: the projected area is 24.64qm.
To enable that less wing curve, the internal structure is more complex (much more diagonals) and the main lines increased from 2 to 3. The lines material changed in the main lines from the LIROS PPSL 275 to the newer PPSLS 180 (SK99). The less wing curve is improving the roll stability.
The canopy material changed from Dominico 40D to Skytex 38 / Easyfly.
The intake shape and the air foils changed, as well as the rods are new and on top and bottom of the leading edge. This was improving the inflation during take off a lot.
The risers are more modern, have less weight and have prints all over.

Can the SONATA 2 be used for basic schooling?

Yes: even the SONATA 2 shows a very high level of performance and a very sweet handling, it is designed to be used for the very first flights on the training hill for normally talented students. In the case the students have a lower level of talent, we rather recommend the first flights to be done with the FANTASIA or SOLA.

Can the SONATA 2 be used for paramotoring?

Yes: the SONATA 2 is a very nice paramotor wing. There the evolution from SONATA 1 to SONATA 2 is most obvious. The SONATA 2 has a much better inflation behaviour and is very well roll compensating. DGAC certification is pending…


The SONATA is an A-wing with 40 cells and many technical features enabling the combination of an extremely high safety level and good performance, a precise handling and a lot of fun. The usage of 30D Dominico cloth and extra diagonal reinforcement in combination with separately sliced finger ribs offer high durability and long lasting form stability.
