ADVANCE Sigma 11 - 22 & 24

ADVANCE Sigma 11 24

I received two Sigma 11 in sizes 22 and 24. 

Launching behavior on the S11 22 at 85 all up, and on the S11 24  at 94 all up is about the same. The glider rises effortlessly in light wind and when the glider passes 80 % it accelerates a bit. A touch on the brakes to keep it overhead is needed and the take-off on both sizes is quick.

At first, let's talk about the size 24.

The S11 size 24 (85-100) flown at 93 all up, flies well at that weight in all conditions, and later I found out that at 97 would be great in strong air. The overall movements of the S11 seem more dampened than the S10, especially the pitch behavior. The S11 pitch seems very calm and neutral in 80 % of the conditions.  The roll movement is also quite more dampened than the S10. Overall its seems to give very little in pilot demand for the C category. I think after test flying the Alpina 4 MS, the S11 24 overall movements are even calmer in the moderate conditions I flew in.  

While the S10 had a little spice, the S11, 24 is calmer in moderate conditions. 

The brake pressure is on the moderate side, slightly less pressure than the Delta 4 and much less than the Artik 6. To describe the linear feel and brake travel to the other C’s, I could say, that the Alpina 4 and the S10 had slightly longer brake travel, the Artik 6, 23 has shorter brake travel, than the S11, 24.  

The brake authority is high on the S11, 24 as the pilot can swiftly carve the glider in the air, and it is difficult to miss a thermal core. 

In biting through the air the leading edge seems to slow just a little before entering at 93 all up, but it enters with high efficiency. At 97 I found that the S11 24 has even a better efficiency into the wind.

Gliding next to a Delta 4 MS at 93 all up, I could confirm that the S11 24 at 93 has the around 95 % the same gliding power at trim and even at the S11, 24 top speed with overlapping pulleys.  The Delta 4 MS had still one centimeter to push. Like the S11,24 goes to 100, and 7 kilos were missing!  then the top speed will increase if loaded at the top. 

Again and again, gliding with very good C’s confirmed my findings that the S11, size 24 shares equally the best gliding of the C category. 

The climb rate of the S 11 size 24 flown at 93, in weak air seems also very good, as I was also next to my friends on their C gliders trying to see if there are any differences. Under the S11 the movements in very weak air ( +0.2 m/s) are very little in roll and pitch, and concentration is needed to feel the rising air.

 In stronger cores, it seems that the S11, 24 climbs also really well, among the best C’s in that matter.   

S11 size 22, 75/87 flown at 85 all up with a Genie light 3 M.The take-off is very easy as the glider inflates really well even in nil wind. In stronger wind, it goes up fast and a dab on the brake is needed to keep it overhead. The turning behavior with the Genie 3 is excellent. An excellent turning ability I can say! I could turn very tight with high precision. The smaller size of course is more dynamic in turns. One day the conditions were really tough at higher altitudes, and in turbulent strong cores, I felt that the S11 size 22 has a slight front pitch and the controls on the brakes lighten a bit even when pulling them at waist height sometimes.  A good high B pilot reported that day when flying next to me that the conditions were quite demanding and weird. The S11 kept a solid structure in those bad conditions without even a single collapse. But it kept me busy in the air, and I could have preferred a higher authority and linear “harder feel” on the brakes rather than a light feel, to control it in those specific and strong conditions.  I thought that I must top land and take another C to compare, but I was high and far to get back. 

The C steering system is very easy to use and very efficient to hold the glider movements in a moderate active air while on the bar! The leading edge seems more resistant to collapse than the S10 and it felt so smooth. I let the glider fly in front of me many times, without any issues. The induced frontals and asymmetries on the size 24 are easy to recover. Big ears are stable and reopen alone on both sizes.  The top speed with overlapping pulleys is around 14 km/h over trim.  For more information, I did update my C comparison for both sizes. 

Conclusion:  The Sigma 11 doesn’t have long rods, yet it is compact enough especially the size 24 in moderate to strong air. The overall solidity is more present on the new version. The handling and overall feel seem tamer in moderate air. The size 22 needs a bit more pilot control in heavy weather.  The turning abilities are superb, and the pleasure feel is high. The difference in brake authority between the S 10 and S 11 is that the S11 turns quicker with the less applied amount of brakes. The overall feedback is slightly less on the S11. Overall, it is a smoother glider to fly. I need to fly the size 24 more on strong summer days in order to be more precise, but the snow is still covering our high mountain range.  A light, compact to pack, high-performance C glider is awaiting you to test fly it :-) 

BGD Base 2

BGD Base 2 M

After the Cure 2 EN-C here is the new Base 2 from BGD. The new generation BGD gliders seems to be developed with very good software, a new designer ‘Tom Lolies’ and it seems that they are quite different from the past creations.

My friend lends me his new glider, and I flew it from 92 to 96 all up.  Launching the Base 2 in nil wind requires a steady pull. It slows a bit at 45 degrees, and a little more pull to get overhead. The inflation in more than 5 km/h is easy and the take-off is immediate. 

I flew the Base 2 on several occasions, and once with the company of two Rook 3 MS at the same load for all 3 gliders! 94,95 all up. 

The brake pressure is on the moderate side. A bit longer than the Rook 3 or the Rush 5  but reactive and linear.  The turning behavior is quite good, with good agility for a high B while having a very calm character.  I could turn the Base 2 inside any thermal while lowering slightly further the brakes in order to get a tight radius. Overall, I can say it has a very balanced turning ability, with no diving in turns and relatively a flat turn.  At 95 all up, I could apply only 15 cm of the brake, and guide the Base 2 in an efficient flat turn, in weak conditions. 

In weak thermals, it seems that the Base 2 has a very good float ability, that enables it to climb really well in the weak stuff even loaded at max weight!   Facing a mellow valley breeze the pitch movements are absent and the Base 2 rises effortlessly and moves forward in the airmass. In stronger conditions, the Base 2 pitch back a little but still climbs very well when I flew it at 92 all up.  That’s is why I felt that the Base2 needs to be loaded at the top all the time for good efficiency in the air, and while loading it, it still delivers one of the best climb rates in the high B category.  The glider feels big, and very calm, even near the top and that’s why loading it at max felt much better.  

Talking a bit about the pleasure in flight, I can say that the Base 2 handling and brake authority allows a newcomer to the high B category to understand and cope better under that machine while having fun. As for expert pilots who desire a direct feel and more dynamics on a high B, they will still feel the reactive brakes but probably will miss a shorter and sharper feel. But I think 90 % of high B pilots would be very happy with the handling and turning behavior. 

The Base 2 comfort in roll and pitch is very high! I sensed that I’m flying a low B glider in that matter. The Base 2 despite the 5.7 AR, absorbs very well the turbulence and the overall movements in active air are present, informative, very dampened, and very calm. The Base 2 delivers a smooth ride all along in XC condition.  The Rook 3 has more pronounced feedback in overall conditions.  It resembles the Rush 5 in calm behavior. 

The trim speed with the same loading as the two Rook 3 beside me is slightly higher on the Base2. The gliding in moving air done more than 4 times and 5 km glide while the Rooks pushed slightly on the bar to match my trim speed, showed me exactly the same glide as my reference in the high B category. The full-speed glide of the Base 2 which seems to have a shorter distance between pulleys, has the same top speed as the Rooks. The glide at full speed showed me also very close gliding results after 5 km the rooks arrived 5m higher…So practically the same and insignificant. 

While at bar, it seems that the C steering is quite smooth, efficient, and easy to use, and I was able to control the glider quite well with total tranquility in most conditions. 

Big ears are easy to hold, stable, efficient, with around -3m/s with bar. The releasing of the ears will enable the Base 2 to reopen by itself in a gradual and smooth way. 

Conclusion: With the new Base 2, the BGD team has succeeded to raise the level of their products as they did on the Cure 2. BGD managed to produce a very comfortable high B, with good handling and top-end overall performance in both climb and glide. I believe that those new high B’s can get their owners to new dimensions and long XC flights while being easy and relaxing to fly. That combination of performance and accessibility is the strong point of the Base 2, and I think it will be quite interesting and rewarding for pilots to test fly it.  But please remember to load it at the top or even at 96 to feel the efficiency in overall conditions. 

BGD Base S at 85 all up

A few words flying the Base 2 S at 85 all up with the new Genie light 3. 

My friend just got him, but as he was busy today, I had the privilege to test fly it! :-) 

The Base S rises easily without any hardpoint. Take-off is immediate. 

I flew in some difficult stable conditions below the inversion, and then I got some two good thermals that pierced the inversion. I will mainly comment on the handling of the S size. The brake travel is moderate, not too short nor too long. A bit longer than the 777 R-Light S. A Bit less than the Swift 5 S, and more firm. 

The pressure on the brakes is firm and not moderately light like the Swift, but very linear and precise. The Base 2 S is more dynamic to fly than the M size which is logical. That little more dynamic feel is what I really wanted from the Base 2 M!  Incredibly perfect feedback and agility! The feedback comes from the risers, not the brakes, in a polite way that enables the high B pilot to follow the movements. 

Getting the super narrow thermals was super-pleasurable, as I could place the Base S exactly where I wanted. The pitch movement of the leading edge is super neutral, with the feeling that the Base 2 S is going through that airmass quite efficiently!  I like that trim speed, quite fast for a high B! The accurate feedback and the glider response in the airmass feel like a higher-rated glider!   In all those tricky, and turbulent conditions I never had any tip collapse. I think flying the Base 2 M or S at max load is the way to go. I didn’t feel any problem in weak thermals, and I felt that I’m gliding quite efficiently at that load. 

Ozone Alpina 4 S and MS

 I already test flew the Alpina 4 in ML size, a bit further down in the posts. 

Here are the S and MS sizes.

I flew both sizes, the S at 85 and the MS at 93 all up. The difference between the A4 and the Delta 4 MS for example is a better launching behavior, mainly due to the lighter materials. The A4 rises better than the Delta 4. The maneuverability and agility are the same, but probably the Alpina 4 has a slightly smoother feel, and the brake's authority seems lighter and felt a bit more linear. 

The overall performance is the same as the Delta 4 in the same size, and also the speed. The S size feels naturally more dynamic, and quite agile.  In turbulent air, the A4 seems to inform the pilot smoothly and accurately better the airmass than the Delta 4. Perhaps it is the light materials, but for me, I was really satisfied by the steering ability and feel of the A4. The differences are really small but noticeable...

Triple Seven King 2 MS (80-97)

Triple Seven King 2  MS (80-97)

The King 2 is Triple Seven 2021 EN-D glider with an aspect ratio of 7.0 

Rods are everywhere from the leading edge to the trailing edge, even on the tips! A selection of thin unsheathed lines all across the gallery. 

Very little openings on the shark nose leading edge all across the span.

The A risers on that King 2 are shorter than the B and C ones. 

Inflation in nil wind is a challenge! So difficult to get it overhead. I tried to move my hands 20 cm higher, holding the lines. When doing so, pulling upward toward the sky as if you are helping the leading edge to rise is the best option to do. Now it is a little bit better. You need a long take off if there’s no wind! 

Inflating the glider at more than 15km/h and holding the lines higher is good. A slow rise that fills the cells and Hop you go.

Flying the King 2 MS at different loads showed me afterward that 97-98 is the optimum weight to fly it.  So i flew the King 2 MS at 97-98 in different conditions with my X rated 6 harness.

In the air the King 2 brake authority depends on the roughness of the air, when it is moderate, the King 2 can be steered perfectly into the core. The King 2 has a relatively short brake travel to steer it in the air. It is not very linear, but agile. I mean it turns quite fast if you apply the brakes, with a short no very linear feel through them. The pressure on the brakes is moderate and harden a bit after 20 cm, but I didn’t use it on all my flights. 

When it is strong disorganized and turbulent, the energy inside the glider will prevent a coordinated and swift authority on the brakes. It needs more time and application to replace it into the core. But overall it is ok. I can confirm that in most moderate air, the King 2 is an agile glider for its 7 aspect ratio.

The trim speed is very fast! In fact the trim speed at 97 matches the speed of the M7 MS (80-95) at 94 with the pilot pushing almost half the speed bar !!!  It is fast. 

Flying it in very weak thermals next to the M7 was a bit difficult to maintain the same height as it is really fast at trim to catch those very light thermals. Slowing it on the brakes won’t really matter. It is better to let it fly. But overall it stays quite ok in super light conditions waiting for the next well-built thermal to go higher. In stronger thermals, the King 2 climbs really fast. The fast trim speed helps a lot in entering that updraft quickly and move upwards slightly better than the M7. 

Gliding in the very calm air next to a similarly loaded M7 showed a little difference in gliding power for the King 2, knowing that the M7 was accelerating to match the King 2 trim speed. That difference in calm air is very little. At full bar in calm air, the same differences occurred. It is only in moving air and in headwind good XC conditions, that the King 2 showed its potential. 

Moving forward and digging faster the airmass and upward rising through the air is toward the King 2.   

The top speed is around 58 km/h taken at 900 ASL. The pressure of the speed bar is slightly hard on the second bar, but still fair. 

The B/C system can be used with ease while applying the speed bar. Smooth and efficient.

The King 2 can be considered a relatively comfortable EN-D glider. It needs more active pilot control than a Mantra 7 for example, but less than the Peak 5 for sure. And also, probably slightly less than the Zeno. 

The King 2 work in itself in turbulent air. It pitches forward slightly but doesn’t go far ahead. The roll movements are also present but comfortable close enough to a Zeno. 

Ears are doable with the outside A’s and are stable. with good sink rate. The re-inflation needs a pilot application to pump them out. Ears are also doable with the C3, and also efficient, and reopen quickly. The sink rate in both A’s and C’s are around 2.5 m/s with a little bar. 

Wing overs are super high, as it can loop only after the second turn!!! Lots of energy ! 

Conclusion:  The King 2 is made for big air and XC conditions. I don’t think any pilot will fly that glider only in very weak and stable air…It will do fine, but that’s not its strongest point. The King 2 potential is for those big windy days,  high bases, and fast transitions. The 3 line configuration of the King 2 helps a lot in getting that compact feel in strong and rough air which isn’t present yet on 2 liners. 

The overall performance of the 3 liners EN-D King 2 is reducing a little bit more the big gap of performance between the 3 liners and the 2 liners.
