UP Trango X-race SM

UP trango X-Race SM   (The hidden beauty)

After flying practically every Trango, here’s the X-Race, the newest Trango version in its light material construction. 

The Trango X-race has a new and beautifully engineered shark nose ! Semi circular, small opening cells, with a complete unsheathed line construction. I actually never seen this kind of lines before. The lower A’s and B’s are heavily coated and feels like a plastic wire ! Of course, this new technology will surely prevent the aging process ! My friend tells me it looks like the kite lines. 

I flew that glider at 97 all up and the next day at 94 all up. I felt that the optimum weight under the SM goes around 95.

Launching the X-race is really easy and without any hanging back at all. In strong wind, the brakes are needed to stop it from surging forward. 

Before the first flight, i remembered the Trango XC3 and thought that the X-Race could bear some of its genes. It doesn’t !

The X-Race felt completely different.

Once airborne, i could sense a more compact and homogenous feel under the X-Race. This glider moves as a whole. It seems that UP did an extensive work on it’s internal structure. Because the yaw and wobbling of the XC3 in turbulent air is no more present. Instead, there’s a new feeling of a coherent, solid, compact feel under the X-race !

It resemble a bit the coherent feel of the Trango XC2(two) but with an increase in comfort and control over both the xc2 and xc3. 

The SM i received had a super short brake travel, which was probably wrongly set, because just one cm of brake pull after the pulley, activated the trailing edge. So i re-adjusted the brakes by allowing a 10 cm clearance after the pulley or the trailing edge response.

Now it was perfect ! The X-race has a moderate pressure. It’s a bit more hard then the xc3 and a bit less than the xc2 and the LM6. The thermals are felt through the brakes which is excellent for a racing machine ! The brake travel is short, linear, responsive .

The X-race with it’s 6.9 aspect ratio is an agile glider in coring thermals ! The compact feel coupled with a coherent structure and a swift, direct brake response, makes circling thermals, efficient and a real pleasure ! I could say it is more agile when circling in turbulent air than the LM6, and the Trango XC3. 

This good handling is integrated in a climbing beast ! The X-race climb showed me a superb climb rate in weak and in strong thermals. The X-race enters the thermal without pitching forward or back. It has the ability to "surf the rising airmass” ! That’s the best way to describe it, as it felt exactly like that !

Each time a thermal is caught, the X-race jumps upward like a spring with a compact feel ! 

Doing some glides in moving air showed an ability to float and move forward giving its pilot a superb glide in racing conditions at trim and at bar!  

Pushing the first bar showed a medium foot pressure and a very flat polar as it seems that the speed increases without the feeling of loosing altitude. The second bar is a bit hard to push on my X-rated 6, and the glide at top speed which is 13 km/h over trim is very competitive with a solid leading edge !  IMHO, i believe that the X-race matches the performance of the today’s best ,3 liner D gliders !

The C steering is a bit hard to pull ! At top speed the pressure is slightly less on your hands as at trim, but still a bit hard to pull. Pulling the C ball has a limiter. Controlling the glider with the C balls is efficient in moderate conditions and the profile remains clean. You can easily pull the C ball all the way when thermalling brakeless, with no event, but i found it climbs best with a little brake pressure.

Ears with outers A’s are stable. Big ears with outers A’s are little un-stable. 

While on bar, pulling the two connected outer B lines are stable and efficient.

Wing overs are easily done on the X-race with a playful character. 360’s also are quick to enter and easy to get out.
Pulling the brakes beyond the hip upon top landing, should be carefully mastered as the X-race doesn't accept to fly very slow with very low pulled brakes. But easy for good pilots to feel.

Conclusion: UP designer and the R&D team has done an amazing job with the X-race ! 

A swift handling, a solid feel, a rocket climber and impressive floater, a relatively easy to manage (high-end C) certified glider.

I believe that the Trango X-race with it’s 6.9 aspect ratio, has the highest score for the overall package of (performance/comfort/handling) in today’s C category. 

Very well sorted flying machine !  :-)

SKYWALK Chili 4 S and XS

SKYWALK Chili 4   (The powerful package) 

Yes …..They were a bit late to arrive !

 Two SKYWALK gliders with an EN-B certification. One is the S size (85-105) and the other the XS size (75-95)  Both are the new CHILI 4 as a high-end B glider which will replace the floatable Chili 3 !

Lets see what SKYWALK did with the Chili 4 who took quite a while in development. I was very curious to see what are the benefits on the B category and i was keen to see if SKYWALK did manage to keep the excellent climb of the Chili 3.

Looking closely at the glider showed a trendy approach with a shark nose, a  pure 3 line configuration, with very small minimalistic and finely tuned line width ! Some lower lines are sheathed and the higher ones are unsheathed. Putting all the lines on one hand, feels indeed very small, it looks smaller than the Mentor 4 ones.

Launching the Chili 4 XS at 92 all up is an easy task with no delay or shooting forward. A simple glider to inflate.

In the air…and already smiling… The brake pressure is exactly to my liking. Not as hard as the Mentor 4 one, nor as soft as the Rush 4 one. It has a moderate pressure with immediate short response. I could put the glider exactly where i wanted with a linear travel !  It isn’t as agile as the Tequila 4, but close enough! I can say that the Tequila has a playful handling, as it dives on quite playfully when you pull hard. 

The Chili 4 has a Joyful efficient handling. It doesn’t dive but has a “flat” corkscrew ability  :-)  !

The pilot can steer it with a much more flat performance turn ! At my all up weight, i was able to core the inside of any thermal. The agility ressembles the Rush 4 or the Swift 4 which are excellent handling gliders.  

With it’s short, linear, responsive and agile character, SKYWALK managed to fix the old Chili 3 handling problem for good !

I’m going to write now a bit about the brand new S size (80-105) flown at 100 all up versus the Mentor 4 S (80-100) flown at 95 all up. (This Mentor 4 S has only around 50 hours) And still in a very good shape and wasn’t flown beside testing and comparing in XC conditions.  Both sizes are flown 5 kg less than the top certified weight.

Gliding along the Chili 4 S with the Mentor 4 S showed a similar trim speed. Probably the Chili 4 S has a 0.25 km/h faster. Comparing the trim speed of the Chili 4 S at 100 all up and a Cayenne 5 S at 100 all up will give the Cayenne 5 a little more speed at trim . (Just for infos only) 

The top speed of both the Mentor 4 S and the Chili 4 S loaded as mentioned above has the same top speed with a slight 1 km/h more for the Chili 4 S.

What are you waiting for ?  ;-)  The glide ? .. or the climb rate ?  :-)   Lets see…

The climb rate in weak and difficult conditions gave me the impression that the CHILI 3 DNA is inserted deeply into the CHILI 4 ! 

But i think it’s much, much better…The Chili 3 was pitching back a bit before entering. The CHILI 4 has a super stable pitch entry ! I was flying for the last months the Zeno, and when the Chili 4 arrived, to be honest i was worried that i have to loose some flying days testing it…as i thought it will have this B feeling in thermal searching and performance feel  !

  I was wrong! The ability of the CHILI 4 to (slide, sniff, surf) the airmass is amazing, just like flying a higher rated glider. When all is calm above your head, you could hear the vario…Bip, bip, bip… It gives the impression to grab every bubble without the leading edge pitch and movements.

It doesn’t attack and search forward, but it climbs slowly and peacefully.  

Flew with my Mentor 4 S near the Chili 4 S, and i felt this edge in float ability as if my friend was flying his Cayenne 5 S ! Each time the thermals weakens the CHILI 4 floats better.

For sure it’s an efficient climber and here again SKYWALK has managed to keep the excellent climb of the Chili 3. 

The glide in calm air at trim and accelerated at full speed is very ,very, close to the Mentor 4 …but… 

In all the testing I have done before on the Mentor 4 and other gliders, I was always certain that if any glider could beat the Mentor 4 in glide it would be pretty awesome! 

especially in moving air !  

For example, I was pretty close to the Cayenne 5 S which eventually had the edge in overall conditions. 

Lots of pilots nowadays still ask about the glide in moving conditions… Well IMHO, it’s the BEST way to see the ability of gliders to surf the airmass efficiently…and it’s not done on a single glide where one can get a lift and other will loose it, it’s done on frequent glides, felt and seen, frequently on tip to tip glide comparisons. 

Doing those glides against the CHILI 4 S was obvious to the eye that the edge was now on the CHILI 4 side !!! 

In overall conditions, the efficiency of the CHILI 4 was tested, felt, and validated, to let me conclude that the CHILI 4 with it’s narrow edge is now the benchmark for the high-end B gliders. 

The problem for SKYWALK now is to create a more competitive Cayenne ! 

Flying in some moderate turbulence, the tips flutters a bit without any consequences. The CHILI 4 moves in turbulent air like any high-B glider.It’s not a super comfortable glider nor a difficult one to manage. It ressembles the Iota, Mentor 4 ability to control. 

Big ears are stable with and without accelerator. They open immediately without touching the brakes. 

If you pull two lines on each side, for much bigger ears, it will be un-stable (a bit). I must find something…  :-) 

Pulling one riser and holding it, doesn’t get a high sink rate and it requires a good weight shift and a little brake control to keep it straight. But so easy to handle for a high B.

Induced frontals are hard to pull in. It’s like the feeling of a two liner. Heavy pull is needed to collapse it. The reopening is average to good.

At full speed, the Chili 4 has around 13-14 km/h over trim and the leading edge still feels solid as pulling the riser doesn’t quickly collapse it.

360’s are efficient and the glider stays quite some turns to exit, so braking a bit the opposite side helps a lot.

Conclusion: What can i do when i feel satisfied with a tested glider beside a large smile ? I’ll happily write about it for you to experience my findings ! 

The CHILI 4 with it’s technical line configuration, need a good B pilot to master it efficiently, like any high end B glider and a careful approach to prepare in bad launching areas, with stones and roots. I found it best to fly the S at 101-103 all up and the XS at 91- 93 all up with no worry about the climb in weak.

Apart from that, the CHILI 4 gave me the sensation of a pleasurable flying machine with nothing but ’top’ overall performance, efficient and agile handling, amazing climb and gliding performance!

All that with a 5.65 AR (4.2 AR Projected) !   A very powerful package ! 

I’m very sure that some serious manufacturers are also aiming for excellence. For now the CHILI 4 has strongly earned its place among the best. Lets see what the future brings.

Beside doing competitions with speed tasks, I always wonder why we always look for higher aspect ratio gliders when a low AR good B can offer us tremendous amount of performance, swift handling, good passive safety, pleasurable feel and a deep happy satisfaction !   

Happy landings  :-) !
