NIVIUK Artik 4 25

 











 NK delayed all my ordered gliders . Artik 4 probably in + 8 months … !! or never...
It was an obvious and clear message. Thank you … :-)
Got many supporting emails… Two pilots even offered to send me their gliders (Really grateful) …
Or an immediate purchase from anywhere in the planet, thanks to all the superb friends in the social media network !
One option taken :
The ARTIK 4 25 is here  :-)
OLivier Nef designs with the Artik 1/2/3 was very good .
First impressions on the Artik 4 seems interesting ...  ;-) 
NIVIUK Artik 4 25

I had received many emails concerning this glider, and i got one against all odds…for a test flight.

I spent time comparing it with one of the best C glider of the moment in terms of climbing and gliding.

The Artik 4 25 launches very easy .It doesn’t shoot forward and stays gently above the pilots head.

Once in the air, the Artik 4 gave me this immediate confidence inspiring feel, ( pillow feel ) , which is becoming more and more difficult to find in today’s C category.

First thermal and the Artik 4 quickly follow the pilots commands in a smooth and obedient circle…The feeling underneath is surprisingly comfortable !

The brakes are relatively medium to short on the size 25 , flying it 90 all up with moderate to light pressure, linear ,precise ,and the Artik 4 can be described as quite agile !
I could place the Artik 4 in the tightest thermal !
Suits perfectly my taste in turning ability and brake feel .

Despite having only 2 lines on the A, and B, risers, the Artik 4 is very coherent and move as a whole structure, without any weaknesses to the airfoil. The energy retention when going for wing overs is very good ! The structure seems very solid !


Gliding performance:
Despite it’s easiness in flight and the superb handling, the Artik 4 gave me the surprise of the year in gliding power !

Going head to head with another high C glider (A 5) at trim speed for about 12 km, showed an equal trim speed and glide with a slight favor to the Artik 4 ! ! (Video soon )
…At second bar the Artik 4 has a speed around 54 km/h at 1000 ASL.

The glide and speed at full bar matches exactly the Alpina 2 SM i have here. (same loadings)

As for the climbing ability the Artik 4 showed me a potential only found on the high C’s . It climbs in the weak thermals (- 0.2 m/s ) as the A5 does… Low saves are indeed saved with the A4 Smile
I sensed that the key is let this glider fly at trim even in the weakest thermals especially when facing the valley breeze. It seems to be more efficient hands up.



Big ears are stable, and a great way to get down if coupled with bar. Wing overs are a delight.The pilot can get over the glider on the second wing ! 360’s gets you down real quick. The Artik 4 will put it’s pilot or the new comer from a B glider in his comfort zone but don’t forget the strong energy retention .


My earlier mishaps with NIVIUK about refusing to sell me the A4, did in fact put lots of suspicions in my mind …It was easy to purchase one…even from the Esquimo people Smile
Honestly…I never thought it will have this complete package !
I don’t know why NIVIUK was trying to hide that glider !
The administration must trust more their R&D creations … Wink

Conclusion: I’m writing this last paragraph , and i’m still thinking of this well sorted glider…
NIVIUK has built an easy C with a high “fun” factor !
It has a moderate aspect ratio, cool handling, crazy performance in this (medium) C segment.


UPDATE:

Pushing the bar at max speed looses a bit in glide, and the flying in strong conditions needs active piloting as the structure snakes around.
