ADVANCE Iota 2 - 25




ADVANCE Iota 2 25

Here it is..The new Iota from Advance that replaces the first version.
What are the visual differences?
A very reduced line diameter with carefully mixture of unsheathed thin lines, and thin normal ones. The C’s are equipped with handles for control at high speed.

Launching the Iota 2 is straightforward with an immediate take off even loaded at top. Easy for a high B pilot.

Feeling in the air compared to the Iota 1:
The Iota 2 feels very different from the Iota 1, where the first version had a feeling of flying a playful B glider, the second version is again agile, but felt more like an oriented XC machine.
Explanation: The feedback is a balanced, calm, roll movement that used to be found on higher rated glider, but…a smooth one exactly to fit the B category. Again, i meant a roll response very comfortable for a B pilot, with the feeling that delivers nice coordinated communications for the keen pilot who was used to fly higher rated gliders. I really appreciate that feature because if i closed my eyes, even in rough air, i could sense that i am flying a high rated glider in smooth air ! So the roll feel is smooth but educational! I hope i made myself understood…which is sometimes a difficult task to describe feelings under a glider.

The brakes has a moderate length, but stil very precise in turns. The pressure is also moderate, and long flights are not tiring at all. Overall i can confirm that the Iota 2 has a very good, XC, handling feel.

Climb rate:
I flew the Iota 2 25 with the best B’s of the moment, and i saw that glider ability to climb in super weak cores like very few B glider ! It is indeed a super floater and a very good climber! It’s a complete change over the Iota 1 which was a bit difficult to climb in weak like i mentioned before. In strong air the pitch ability is nearly absent and the Iota 2 …just climb… without any weak point whatsoever.

Coping with turbulence:
Flying the Mentor 5 and the Iota 2 25, i can’t comment if one is more comfortable than the other..they are both very comfortable to fly and similar in that aspect. The Iota 2 25 seems also easier in turbulence than a Chili 4 XS for example.

Glide and speed:
Lots of pilots will read that section as if it is the most important one…But for me it’s the overall package that matters… Now really the bar is high, with amazing gliders in the B category.You probably have rated my B comparison concerning glide. The Iota 2 is no different to be with the leaders in that matter. I think above that by just a little, you will reach Sigma 10 glide performance !
The Iota 2 25, has a high trim speed, higher than a Mentor 5, Chili 4, Cumeo, if all are similarly loaded. The glide at trim speed for the Iota 2 25 seems right on top like i mentioned with the Mentor 5, Cumeo, Chili 4.

The strong point of the Iota 2 25 is the way it enters the thermals in gliding mode, and i’m just talking at trim for the moment. The Iota 2 surfs the air upward and floats forward for an efficient gliding into a moving airmass. It feels solid and just floats upward. I really liked that characteristic for a high B !
At full speed the Iota 2 25 has some 10 km/h over trim to block the pulleys. The M5, and the Cumeo could have 2 km/h faster. The glide at top speed is close to the high end mentioned gliders, but what i discovered flying the Iota 2 25 that differs is the super stability at top speed ! I mean it’s really stable, and i couldn’t know the difference in behavior between flying at trim and at top speed because it felt the same, but with a wind that increases…The C handles are a nice way to control the glider in high speed, but since the iota 2 25 is so stable at speed, i don’t see that it will be used much  ;-)  Of course in strong conditions, they will.. :-)






Ears are stable and reopen quite normally.
Induced asymmetries are soft and going keeping course is easy and also counter steering. Frontals are a bit deep, horse shoeing a bit, slightly dynamic than the M5 ones, but they open very fast, and it seems they fulfill the B certification requirements.

Conclusion:
The Iota 2 25 was mainly created for XC use with a good and educated roll feedback for any good B pilot. The overall comfort is high. The trim speed will enable efficient ridge crossings in turbulent air as well as the use of the speed bar which is light to moderate, with a more sold structure, and totally usable.
Overall gliding performance and especially climb rate are strongly implemented into this XC machine.
Video soon...
Cheers,
Ziad

PS: I’ll update my B comparison in the next days, for more details.

Skywalk Cumeo XS

Skywalk Cumeo XS 
  
After the beautiful Chili 4 XS, here’s the light version called Cumeo. 
After test flying many wings I’m now more and more convinced that even with the same glider technical details, gliders with lighter materials, will have different feel with sometimes enhanced performance or sometimes much less ! 
I’m no engineer to debate on that, but i’m positively sure and the reality of things is well shown. 
In the following review, the Cumeo will show its true identity. 
  
Launching the Cumeo is as easy as a school wing… 
  
In the air: 
I flew the Cumeo from 90 to 95. In strong conditions, 93, 95 would be superb. At 90 all up if flies beautifully in moderate conditions. 
  
Handling: 
Compared to a Chili 4 XS, with similar load the brake pressure is lighter on the Cumeo with slightly longer travel. Nevertheless, the agility is very present. I could place the Cumeo inside the thermal very precisely. The Cumeo feels more tamed and very subtle to fly than the Chili 4 XS with same load ! The Cumeo XS also gave me a high degree of flying pleasure that i could describe as (a walk in the park eating my best ice-cream ;-) ) 
  
Climb rate:   
Flying the Cumeo at 95, I could strongly confirm that it’s still a floater! In very weak conditions, the Cumeo even loaded does real catch those tiny lifts. At 90, it’s a thermal beast!  Even in wider conditions, the Cumeo still pushes forward entering those cores with ease and a smoothness feel. 
  
Glide angle: 
I flew the Cumeo XS next to the Mentor 5 S, Chili 4 XS, Iota 2 25, to conclude after many glide comparisons “and it took me a while”… That the Cumeo is definitely among the best ones in that matter especially if I want to consider top end speed glide ! 
In fact IMHO, it sits right on ‘top’ next to the glide contenders if going in a speed chase. Doing some glides in turbulent air, the Cumeo seems also very efficient, and probably slightly more than a Chili 4 XS  (slight margin) May be because it doesn’t have the pitch behavior of it’s ‘regular cloth’ sister. 
  
Speed: 
The Cumeo has a slightly increased top speed above the Chili 4 XS if both are fully loaded. 
  
Big ears are very stable. Much better than the Chili 4 XS. They reopen quickly. 
Landing in narrow zones is one of the Cumeo strong points. It can be slowed quite well. 
  
Conclusion: 
Yep…It’s a positive test…The Cumeo XS deserved it very well…It is very obvious that if a glider is relatively easy for a high B, loaded with top end performance characteristics, light to carry, handles like a dream, soft in reactions, a highly balanced B glider, and can get you efficiently on any XC would not be highly recommended. It is ! 
In today’s market, there are very nice high B gliders from different manufacturers. The top 3-4 holds a very close and sometimes insignificant difference in overall performance. But what differs is the feeling, satisfaction, and the sensations you get when you are flying a special one. I’m sure, the Cumeo will be among those ! 
Now it seems that I wrote too much…i know…Sometimes i get carried away  :-) So please forget what I just wrote ! But I will be very intrigued if you, the interested pilots, looking for a high B ‘light’ glider, would test fly the Cumeo XS from 90 to 95, and comment back… 
That would be quite interesting :-) 

  
Ps: I always mention that other sizes could be similar and sometimes could be different. Please respect the loads under any glider. A glider flown at mid weight or less will (surely) have other feeling and results. 
IMHO, I think that loading a glider beyond 75 % of its weight range will make you a pilot rather than a passenger. 
Happy flights :-)
