B comparison UPDATE.
UPDATE with the Buzz Z5
I have simplified a bit this B comparison, and added the ‘more fun and pleasure to fly B glider, as many pilots don’t always search for + 0.xy in LD on a B rather than “higher fun factor ” glider.
Also i threw some C’s and D’s to give an idea…
Most easy to fly in difficult conditions (most comfortable) :
1-AD Rise 2 M = Atlas X-Alps S = Buzz Z5
2-Hook 3 25 = Base M
3-Sprint EVO= Eden 5=Advance E7 26 = Kantega XC2= Ion 3 S = Atlas S= Infinity 4 S = Swift 4 SM = AD Rise 2 S Superlight
4-Rush 3 = Mentor 3 S = Summit XC 3 S = Iota 26 = Triple Seven Rook 2 SM = Ikuma 25 = Skyman Cross country S
5-Mentor 4 S = Tequila 4 = Rush 4 = Windtech Bali = Skywalk Aruba 3 S = Carrera Plus S = Mentor 4 Light XS
6-SM-Blacklight = Nevada = Sky Atis = Comet 2 S= Swing Mistral 7 S
7-Mentor 2 = Lightning S
8-Chili 3
9-Carrera S, M
Climb rate in very weak conditions (float-ability)
1-Carrera Plus S @ 91 = Chili 3 S @ 98 = Infinity 4 S@ 90 = UP Kantega XC2 S @ 90 = U-Turn Blacklight SM @ 98 = Atlas X-Alps S @ 92 & M @ 102 = Swift SM @ 90 = Skyman Cross country S = Buzz Z5 SM @ 88
2-Nevada = Rush 4 SM @ 90 = Mentor 2 S (Still Efficient) = Tequila 4 SM = Mentor 4 Light XS
Hook 3 = Eden 5 = Carrera S, M =Triple Seven Rook 2 SM = Lightning S @90 = Arriba 3 S @ 92.
3-Mentor 3 S @ 95 = AD Rise 2 M = Atlas S @ 90 = Base M @ 90 = Rise 2 S Superlight @ 90 = Iota 26 @ 95 = Windtech Bali @ 95= Mentor 4 S @ 94
4-Summit XC 3 S @ 93 = Comet 2 S @ 88 = Ion 3 S @ 95 = Ikuma 25 @ 94.
5- Sky Atis 4 = Advance E 7 26 = Swing M7 S @ 92
Climb rate in OVERALL conditions for XC flying (difficult ,weak, or strong) .
“Relatively moving conditions”
1-Carrera Plus S @ 94 = Chili 3 S @ 98 = Carrera S, M =Triple Seven Rook 2 SM @ 93 = Swift SM @ 92
2-Nevada = U-Turn Blacklight = Rush 4 SM = Mentor 2 S (Still Efficient) = Mentor 3 S ( it is very dampened) = Tequila 4 SM = AD Rise 2 M = Atlas S = Base M = Rise 2 S Superlight = Atlas X-Alps S & M = Mentor 4 S = Buzz Z5 SM .
3-Iota 26 = Windtech Bali = Arriba 3 S @ 92 = Ikuma 25 @94 = Skyman Cross Country S
4-Summit XC 3 S @ 93 = Comet 2 S = Ion 3 S
5-Hook 3 = Eden 5 = Sky Atis 4= Advance E 7 26 = UP Kantega XC2 S = Infinity 4 S = Swing M7 S = Lightning S @90 (These gliders have a superb climb in calm conditions away from the valley breeze. Differences are very small .Its up to the pilot !)
Glide in “OVERALL” conditions (upwind, downwind, racing in difficult conditions) Or “efficiency” ! Done in active air.
1-Carrera S, M = Mentor 4 S = Iota 26 = Carrera Plus = Rook 2 SM = Mentor 4 light XS
2-Mentor 3 S = Chili 3 S (Differences between 1-2 are insignificant ! )
3-Rush 4 = AD Rise 2 = Swift 4 SM = Ikuma 25
4-Nevada 26 (must be loaded at 100 ) = Windtech Bali = Hook 3 = Tequila 4 SM = Mentor 2 S = Arriba 3 S = Skyman Cross country S = Buzz Z5 SM
5-Blacklight SM (loaded) = Ion 3 S = Sky Atis 4 M = Swing Mistral 7 S = Atlas X-Alps =AD Rise 2 S Superlight = UP Summit XC3 S size (M&L could be different) = Atlas X-Alps S =UP Summit XC3 S.
6-BGD Base M = UP kantega XC2 S = Rush 3 M = AD Rise 1 = Infinity 4 S = Eden 5 = Comet 2 S = Atlas S = Advance E7 26 ( The differences are small with ± half a point in L/D max, in “relatively moderate conditions” . (Racing in stronger conditions will show bigger differences)
Fun feel : “pleasure to fly, “agile” and higher overall fun feeling” IMHO
1-Tequila 4 S @ + 91 kg = Arriba 3 @ 90 all up
2-Base M @ + 91 kg / Infinity 4 S @ + 89 Kg = Swift 4 @ + 91 Kg / Atlas S / Sky Atis 4 M @ + 95 Kg / Swing Mistral 7 @ +92 Kg / Mentor 2 S @ +95 Kg / Comet 2 S @ + 93 Kg / Mentor 4 XS / Skyman Cross country S = Buzz Z5 SM @ 90.

C & D gliders:
This grade is to say how busy a glider is, in strong conditions, or the one that’s more difficult to manage, comparing to the B category.
Since this is a very delicate comparison , i must point out that the glider that has quicker authority on the brakes like the Triton 2 will enable a good pilot to keep it swiftly overhead. Some doesn’t have that quick response and in strong conditions they won’t keep the pilot as busy, but he will be the ‘passenger’ for a short lapse of time …
The grade doesn’t indicate the one that recovers easier or harder !!Only that keep you busier ! Most will have easier recovery than the higher graded !

The Eden 5 has less top speed of 3-4 km than the others.
The Hook 3 is very comfortable to fly with a very interesting glide angle. The climb in smooth conditions is fair.
The Mentor 3 is much easier than the Mentor 2, and its efficiency is in those turbulent glides where it will have less pitch movements and little better glide.
The Mentor 4 has better glide than the Mentor 3 especially in head wind racing. Flying the M4 at 60 % of the weight range will give you a very good climb in weak.Flying it at top, will loose the ability to float in weak climbs.
The Ikuma is a comfortable glider with nice handling. The overall performance is is in the mid of the High B category.
The Iota has a very good glide similar to the Mentor 4, It has a nice climb similar to the Mentor “3”.
The Chili 3 S “still” has the best climb rate and a very nice handling in homogeneous conditions. But with a very long brake travel.
The Advance E7 26 is the most confidence inspiring rock solid glider of the cat. It reminded me of the low B cat in comfort.
The BGD Base is a confidence inspiring, solid glider.The climb and handling are very good.
The Atis 4 has a bit roll movement and need some active piloting in the high end B’s.
It has a fast trim speed, much like the M3 and Chili 3. Long brake travel are needed to let the glider respond in turbulent conditions.
The UP Kantega XC2 S is a very nice wing to fly .It has nice handling and also superb climb overall being also very accessible.
The Swing M7 S is a delight to fly. It dives a bit into turns. It is fast enough for a B, and has enough performance. Not really a floater but a nice glider overall.
The Rush 4 has a very good glide . It is an overall good, very solid B glider, but its trim speed is around 38 km/h and especially the top speed which is low for the cat around 51 km/h .
The fastest are Mentor 3, XC3, Mistral 7…But it is around 55 km/h max.
The AD rise 2 M has the BEST ratio Performance/Comfort in flight !
The Tequila 4 SM is like a precious gem ! combining agility/performance/accessibility!
The Infinity 4 has a very light and nice turning behavior! It has a low trim speed , and the climb rate even loaded is outstanding!
The Comet 2 S give a nice feeling under it. It has a very nice handling .
The Windtech Bali has a respected glide angle. It needs slightly active piloting in big air.
The Atlas S has everything to make its pilot very happy,with a good feeling of passive safety. The X-Alps version of the Atlas has more performance overall, especially in climb.
The Arriba is slightly more dynamic than the Tequila 4 and a pleasurable glider to fly.
The Rook 2 is a well balanced high performance B glider, with nice handling and efficiency.
The Mentor 4 light XS is a sublime glider ! light, agile, performance oriented, a complete XC B glider.
The Cross Country S is agile, easy to fly, has nice performance, efficient ears, light to carry, a sweet glider to keep for adventure bivouac and XC flying.
The Buzz Z5 is a docile, fairly agile B glider with everything from excellent float-ability, to good glide for the low B category to get you on far XC's. If you want it more efficient to get close to some high B's, just load it, sit back ,relax and enjoy the smooth ride Smile .
Conclusion: The Carrera has now two very serious competitors, the M4 and the Iota in pure gliding power.The Carrera still climbs better “in real conditions” than any B in this table.
The Carrera plus climb is even better than the original version only in weak and moderate conditions.The more the headwind, the original version cut forward more efficiently but if you are loaded on the plus version ,and using the first bar, it would be difficult to be beaten even on some higher rated gliders Wink ...
The AD Rise 2 is very comfortable to fly with a superb glide for the high B category .
The Rush 4 like the Swift 4 has nearly the glide of the Mentor 3 but with lesser speed. It's an overall efficient glider in difficult conditions where it could cut through turbulence and have a very solid and compact feel coupled with a direct handling.
The Mentor 4 has now the best glide in difficult conditions among the similar aspect ratio B’s very close to the Iota and the Rook 2. The climb in very weak conditions still favors the Mentor 3 S similarly loaded.
The Atlas X-Alps is an easy “all rounder” with very good performance especially in weak climbs and low saves.
The Buzz Z5 is more agile than the X-Alps and slightly less than the Tequila 4. It is more comfortable than the T4, and will keep you slightly busier than the X-Alps. The overall package of usability and performance is superb.
I’m certain that a good pilot can break an XC record with ANY of those superb B gliders from above !
Please pick the one that will make you feel happy under it ….The rest is up to you !
Cheers,
Ziad
