The Concept:

It’s the “ultimate” 3 Liner.

We questioned whether or not the replacement of the M4 should be a 2 liner or a 3 liner. Developing the LM5 for the X-Alps helped us making the decision. The 3 liner option was more appealing in many ways.

We are confident that the M6 is going to be a classic: It is our best ever 3 liner for keen XC and competition pilots.

New Features:

• A completely new structure; based on the architecture of the Delta2, but adjusted to work on a sail with a higher AR.
• The higher flat AR of 6.9 gives better climb performance. We used a high arc to help the sail’s tension in order to give the wing more cohesion and very importantly to keep good roll authority in the turn. The result is precise handling, without the feeling of flying a wing with more AR than the M4.
• The M6 features SharkNose technology. The forgiving nature of the profile at low and high angles of attack sharpens the handling and gives a high level of spin resistance. This allows the pilot to make deep brake inputs when necessary to adjust the turn and bank angle as required.
• At low angles of attack the SharkNose profile gives more solidity or collapse resistance than a ‘classic’ profile as used in the M4. This improves the True Performance making it more useable in turbulent conditions and due to the stability of the chord, the pilot will be able to fly more efficiently.
• Flying the M6 on the rear risers is also more intuitive than with the M4. The feeling on the Cs is more linear and the effect on the wing is more progressive and effective.
• Thanks to the good stability and the good testing behaviour, we were able to extend the top speed by a few kph.
• Line drag optimisation: 22m total line length and 19% saved, compared to the M4.
• Max glide improved by 0.7-0.8pt and the glide at the max speed of the M4 has been improved by at least 1pt!
• Advanced 3D shaping, to improve the airflow on the LE, and MiniRibs to reduce the drag at the TE.

Your M6 and SIV

The M6 was certified with the use of additional collapse lines for accelerated manoeuvres only.

The M6 is a new generation wing which incorporates our latest technology from the LM5 and Enzo2. Alongside the SharkNose, one of the developments we have incorporated is moving the A tabs further away from the leading edge and deeper into the chord. This makes the wing more collapse resistant; more solid, stable and confidence inspiring.

It is possible to perform SIV training with the M6, in fact we strongly recommend it. Trim speed symmetric and asymmetric collapses using the A risers to deflate the wing as normal are possible. However, we strongly recommend to not perform full speed symmetric and asymmetric collapses with the A risers alone. All other manoeuvres however, are possible.

Pulling the A risers or collapse lines is an artificial way of simulating real life collapses. In real-life collapses the M6 behaves in a similar manner as any other wing in the same category, however, to induce a full speed collapse that conforms to the EN certification requirements it must be done with the use of additional collapse lines. When you induce a full speed side collapse without using collapse lines the results may be different than during certification because the canopy pre-accelerates*, further increasing the artificiality of the test. Using collapse lines reduces the amount of pre- acceleration, this makes the collapse more in line with certification requirements. Collapse lines need to be mounted accurately, with attachment tabs sewn into the nose of the wing, but since they are not supplied with the wing we strongly recommend to not induce full speed symmetric/asymmetric collapses at all.

*Pre-acceleration is when the glider accelerates before collapsing. Imagine flying at full speed and pulling an A riser to induce an asymmetric collapse (remember using the A riser is already an artificial way of simulating real life collapses). With the A’s further back in the chord, instead of deforming and folding immediately, the side that you pull actually accelerates first (because of the reduction of AofA), thus momentarily causing a turn in the opposite direction. Therefore, at the point of collapse because everything is not in line – slight turn, slight roll/yawing action in the other direction – collapses are even more artificial, with potentially a greater kink angle, more chance of shock re-inflations and possibly more dynamic reactions. Such collapses are outside of the requirements of EN certification and do not represent the majority of real life collapses.
