Cobra Canopy

[Chief 0]

I am about to try a Cobra 190 canopy. It is not the size I question, but the make. Is anyone familiar with a Cobra and any secrets to pass along before I jump it. The canopy is not known at the local DZ, hence I must solicit the help of my on line DZ friends. Thanks and Stay Safe!

[SkymonkeyONE 3]

never heard of a Cobra.

I've done some searches and all I could find was a company called SkyDepot, but their website is dead.

The cobra canopy is a square platform of 9 cell, flying and sizes similar to sabre, manufactured by Atair and sold in the past by Winchester Tecnologies - Sky DEpot in USA with sales of the canopys Alpha

Personally, I've never heard of it.

Five out of nine dropzones in the Netherlands do not have them - all cater to students.
Might you be speaking for Atair instead of on personal title?

[PhreeZone 15]

Or might they just be popular out side the Netherlands? Europe is a big country... PdF is popular in a lot of the western parts... Atair is popular in Eastern Europe from all accounts.

Flight Concepts is popular in its geographic area here in the States... but go outside that area and no ones heard of it. PdF will not sell its canopies to America so its basically unheard of here while its popular in Europe.

And tomorrow is a mystery

Thanks Dan, the information is useful. I look forward to jumping it Wednesday. I shall let you know how it flies. Again, thanks. . . . Bill

[roq 0]

I know and I tried the European Spark canopies. In my country there are some to fly.
The Spark is similar to sabre in Aspect Ratio and Glide ratio but that I know the Spark is better than the sabre in special in opennings.
The fabric of the Spark is ZP Gelvenor like the Atair canopies.

I certainly am no expert; I tried to limit my statement to what I know, after four years and only one dropzone outside of my own country.
Europe certainly is a big place, at over 30 countries :]

There are couple of Sparks in finland and even couple in our dropzone. What i've heard from people (never tried one myself) is that the openings can be quite painful. I heard from one Spark owner that he had to install pocket slider into that before the openings calmed down. Of course, openings can be user/canopy individual specific.

It can happen, but in my country all spark owners (models student 230, 190 and 170 that I know) they speak about very good and soft opennings. Such as I verified in test.

"Such as I verified in test. " Thanks, you are the first to have personal first hand experience with this canopy. I will reply/post after I jump it. Hopefully, this week end. Thanks . . . Bill

Saw one in flight used by Skandinavian jumper. She had around 1000 jumps, so hardly a beginner, but the thing just didnt want to surf/plane out. She crash landed all the time. I wasnt impressed by the glide or flying of this Spark,r eally.

However, Performance Variables (or Atair on their behalf) makes Contrail,which is one of the best flying 9 cell elipticals I saw. Faster than Stiletto but very smooth and with excellent glide! Very much like Impulse/Cobalt or the (S-African) Hurricane that also pretty much impressed me.

[Chief 0]

Thanks for the information (with hesitation) I will jump it this week end. At least now with the information I can plan for no plane out and a hard landing. Thanks . . Bill

As a former Spark owner I can confirm that the openings are awfull from time to time. By rolling the 4 tunnels from both sides into tight roll and tucking that next to the center cell and pulling the slider over the opening of the center-cell and rolling the tail TIGHT it can be made to open semi-softly - the openings are still fast but they do not hurt

When you get to know the packing and don't mind the ocasional slam the canopy is a very nice "first canopy" - very nice glide and flare, just a little bit lighter front riser pressure than the Sabre and overall very nice canopy to fly - I liked mine very much - oh, and the fabric is the same nice-to-pack one the Cobalts are made of, so no wrestling with the canopy when packing.

Thanks Kari; I certainly appreciate your first hand knowledge. Typical Cleveland, Ohio weather - it is raing today so I must post pone jumping the Cobra until Sunday. Stay Safe . . . . Bill

Does Bobby have the Westwind this weekend?

to be moving that fast!"

Yes, Bobby has the Westwind and a pilot full time for the rest of the summer. He will even fly it during the week if enough jumpers are there.

I jumped the Cobra today and it flew/landed great. Thanks for your info

[Chief 0]

Hi Rog: I jumped the Cobra today, It flew well and landed even better. I rolled the nose about 3 times and the tail about 8. Opened nice. Varifying your test - I agree! Thanks . . . Bill

[Chief 0]

Flew the Cobra today and it was good. rolled nose and tail. Opened nice and flew well. Thanks. . . Bill
