NOVA Sector S

NOVA Sector S 
After 10 years, NOVA finally released their new C replacement. A flat aspect ratio of 6.0, unsheathed lines all over and  a 3 line configuration setting. 
The factor 2 is made with light fabric and the S size weights around 4 kg.

Launching the light cloth Sector is easy in all conditions. Those light gliders can launch even without touching the A's ! 

I flew the Sector S at 95, 96 all up. This load enabled the Sector to be quite taught and efficient in all conditions.
IMHO, Its better to put the exact pressure in a car wheel in order to take corners at high speed. Any less pressure in those wheel won’t give you optimum efficiency. It’s the same with gliders they will perform much better (when they reached their optimum shape design) by loading them precisely. I think 95 is a good balance under the Sector S size. 
Of course the Sector S can be flown at mid-weight, but will loose it’s inside pressure flying it in turbulent air, as all other gliders do in it’s category.  

The brakes have medium pressure  until 15 cm of pull then they are slightly heavier. The Sector S at my loads need 2 (two) centimeter of pull, to turn it !  The Sector is an agile glider that doesn’t dive in turns even when lowering the brakes while circling. It tries sometimes to get out of the turn if the brakes are released, and some weight shift would be also quite beneficial in tight small cores.  

I flew next to a Delta 3 MS and Alpina 3 S in order to know the overall performance of the Sector S. In weak thermals, ( less than 0.5 m/s) the Delta 3 MS and the Sector S are very close in climbing ability. 
You can look at the C comparison as it has been updated with the latest C wings for small details if you wish…

In well built thermals, I mean over 2 m/s, the Sector jumps upward like a powerful but well mannered horse ! It really climbs very fast ! I think it has one of the best climbing ability in those thermals like a high end C ! It doesn’t pitch back, it does very slightly pull you into the thermal with power ! I personally like that behavior ! Some pilots would like the calm surge behavior of the Alpina 3, some would like the ones on the sigma 10 or the slightly sharper one on the Sector S. 

In turbulent thermals, i found that the Sector behave like a small energetic kid. The risers are more nervous than the S10 in translating the airmass. Don’t understand me wrong, the Sector quality of telling you what’s going around is quite nice for sensible pilots. The informations of the air are transmitted mainly by the risers. I was finding the Delta 3 to be quite tame to my personal taste in feel under the glider. Some pilots over-heree loved the Delta 3 soft feel ! It’s about taste…The Sector is more informative. 

NOVA did mention that the Sector S is between the Mentor 5 and the Triton 2. I think it’s quite accurate, but i have to add, with a slight shift toward the Triton 2 S in feel underneath the Sector 2 which i think shares its DNA.  If you think that the Mentor 5 is quite lazy to your taste, you will find an interesting feel with some tasteful but quite manageable spices under the Sector 2. 
This has been said, i have to add also that the Sector 2 remains in the middle of the C class in terms of piloting level. It’s an easy C for a pilot who already has two full seasons on a hot B. 

Gliding properties:
For an aspect ratio of 6, the Sector S glide angle angle is similar to the Delta 3 MS at trim and especially at full bar, with 1 km/h faster on the Sector S if both gliders are similarly loaded. Trim speed is similar. 
Gliding in turbulent air, is as efficient on the Delta 3 as it is on the Sector S !  
The Sector S ridge racing and gliding in thermo-dynamics is quite efficient ! 

Big ears have moderate stability and reopen without pilot input on the S at 96 all up. 

Conclusion: The trailing edge look quite weird and wavy…but it could be a design for efficiency… The Sector S is an informative wing that shows you what the air is doing, but middle C glider in terms of piloting level. 
The strong point is the climb in good thermals, that showed me an impressive search toward the lift. A very good glide angle for the C category, at trim and especially at full bar, fast enough, handles well. 
A strong contender in the C category for sport class competitions, and interesting XC potential for sure !
This is only my opinion. Make your own !

Hi Ziad ! Thanks a lot for your article ! Very interestikng as usual, plenty of informations on wing behaviours !
I would like to know... How would you compare Sector to Queen 2 and Lynx ?
Thanks for your answer
