The Ultimate XC / Serial Competition Wing, Certified.
We cooked the M4 using the revolutionary recipe for the R10, but added some spice and a deliciously satisfying amount of comfort and agility in order to make a better M3: an M3 with more performance.
The M4 is a very close evolution of the M3, which has been updated by applying the latest in comp wing technology. Even if the difference is small on paper, the step forward in real performance is big.
The AR of the M4 is the same as the M3. We didn’t want to compromise the sail homogeneity, and its overall feel of comfort and accessibility in the category.
The internal structure and the rigging remain the same. It’s the perfect balance between optimisation of lines, the weight of the canopy, and the overall tension achieved for this aspect ratio.
A more efficient overall design has allowed us to increase the wing loading in order to achieve an even more cohesive feel, better precision in the turn, and more speed. Needless to say, the climb rate will remain exceptionally good, just like the M3.
The complex recipe of revolutionary new features from the R10 has been applied to the M4. Although we unfortunately can’t even tell you all of the details, everything that can be done has been done to make the wing more efficient and more drag-free while staying well within the boundaries of the EN D class.
The trailing edge remains similar to the M3 with miniribs. This helps to reduce drag by improving airflow at the TE. Also, shrink tab attachments form a clean ‘flap’ at the trailing edge.
The leading edge has been constructed in the same manner as the Delta. We replaced the mylar with nylon rods, which helps to save weight and ensures high longevity and profile form retention at this crucial area of the wing.
The line geometry and material have been optimised for a 10% drag reduction from the M3.
The risers remain the same with 12mm Cousin webbing, and feature super smooth top of the line Ronstan pulleys for easy speed bar use.
Line construction has been improved. Internally reinforced line loops strengthen the most highly stressed line junctions. Bottom loops of all riser lines are now protected in a sheath, for increased strength and durability.
The M4 is constructed from the same materials as the Delta, which has created a reduction in weight of 200g.
We have added an extra size in the range, the MS. This will reduce the gap between the optimal weights of each size. We have also extended the max weight of the L by 3kg, to 120kg total.
Diagonal ribs have been redesigned in order to provide better support to the line arrangement, especially at the Leading Edge.
