My last flight on a Skywalk D glider was on the Poison X-alps size S (70-90).
The New Xalps 3 is the wing that have won the 2017 X-alps with Christian Maurer, and third place with Paul Guschlbauer.
This new version was especially made for the X-alps with very light cloth and Dyneema risers. It’s the Hike and fly Skywalk latest competition wing.
Taking off in light wind is easy on this 7 aspect ratio glider.
I have the LM 6 in size MS (80-95) in order to compare the differences in behaviours and feeling under those gliders.
With same loadings, (92 all up), the Xalps is +2 km/h faster at trim speed. At full bar it’s also 3 km/h faster.
In turbulent and strong conditions, the Xalps 3 needs active piloting much like the Poison X-alps in size XS i had earlier.
I found out that the Poison Xalps XS handling was slightly sharper, and i was more connected to the glider by the brakes. This may be because of the smaller size.
In light thermals (-0.2m/s) i found out that the LM6 has slightly more float ability , and can stay longer in those tiny lifts.
In stronger thermals, and difficult conditions, the Xalps 3 is much more efficient. Adding a wind factor, the Xalps 3 moves forward efficiently. It has slightly more efficient performance than the Poison Xalps.
Now things were getting more serious when i activated half bar on the Xalps 3. It is fast and efficient wing for racing ! The LM6 is also a very nice glider, but racing near the Xalps 3 is a difficult task for the LM6. The Alps 3 keeps going forward in a fast glide efficiency.
I turbulent air, the overall comfort under the LM6 is quite high compared to the Xalps 3. In the same turbulent air, i needed more energy to control the Xalps 3.
In turbulent air, pushing the bar on the Xalps 3 is lighter than the LM6, but need more active piloting also. The C risers are very efficient, and can control the pitch movements quite fast. In fact at first bar the Xalps stiffens in pitch surging…but some slight roll movements are present depending on the conditions…
Ears with outer A’s have moderate stability. On bar they flap a bit. Ears with outer B’s is doable, stable.
Conclusion:
A light competition race eficient wing for sure. Needs active piloting. The Dyneema risers are very small and the attachment points to the carabiners are 0.5 cm in width surely for weight reduction ! The brake handles are also very thin (0.4 cm) and better use with glove for comfortable hours in the air. This riser configuration is extreme, for the ultimate hike and fly competition pilot.
Racing in windy and strong conditions is the Xalps 3 strong point.
X-alps athletes has already flown that glider multiple hours and i hope they can comment much better on it's overall behavior.
This is just a small idea for pilots who don't have the chance to test fly one.
