closed endcells

[livetofly 0]

I have been continually getting closed endcells on deployment. It is always on the left side and it always happens. I bought my canopy used and dont know if i this is something i can correct with packing or its just a characteristic of eliptical canopies. Any thoughts?

I have a sabre2 170 and get end cell closure on every jump...apparently that's just the nature of the canopy

What is your wingloading?
How many jumps are reported on the lines currently on the canopy?

I doubt it has anything specifically to do with elliptical canopies. My old Manta 288 used to get end cell closure on every single jump, but even with only 7 cells fully inflated (7/9 of the canopy, or 224 of 288 square feet) my wingloading was still below 1:1.

i just looked up the stiletto, and as far as i can tell this is not a hybrid, correct? is this the canopy you're still jumping?
the reason i ask is because i also have this problem (student canopy-skymaster). mine is a zp/f111 hybrid and from what i gather off here, that's why mine does that. it fixes itself as soon as i do my control check, but might be something to consider.
for clarification, i am still on a student canopy, just curious if maybe that is why...

question: would a lower WL cause this? or is it more likely the fabric or something else is the cause?

i didn't lose my mind, i sold it on ebay. .:need a container to fit 5'4", 110 lb. cypres ready & able to fit a 170 main (or slightly smaller):.[/ce

I don't really have the experience to comment on the specific flight characteristics of specific canopies, so I'll leave that one alone.

There are a number of threads that have covered end cell closure in various situations:

i wouldn't be comfortable if the canopy i owned did that on every opening (once i dooooo own one!)
i read somewhere on here the fabric does make a difference and asked my instructor, and he confirmed it. but i wonder about wing loading...
i'll have to remember to ask!

My Stiletto occasionally opens with closed end cells, but it's always symmetrical.

What are you doing to the nose when you pack it?

On mine, I leave the nose alone and just quarter the slider and have fantastic openings.

I've been demoing a pilot 210 lately, loaded at about .9 and it always opens with the left end cells closed. So, I left the nose alone when packing it - same thing - left end cells closed on opening. I even rolled the nose OUT on the next few pack jobs to see if that made a difference. nope, still end cell closure. I guess it's inherent to the canopy. FWIW, I had the same experience on the same size sabre2 I demo'ed for a bit.

Its not a deal breaker though - just hold it in brakes, they inflate and the fun begins. I really like that pilot

Performance Designs discusses the common occurrence of end cell closure in their FAQ section. A ram air canopy opening with a delayed inflation of the end cells is very common and is usually not a problem. If it is always on the left side it could possibly be a result of improper line trim, or it could just be a fluke. Here is a link to the FAQ for more info. http://www.performancedesigns.com/faq.htm#a1

Same as bdbrown reply

I have soft openings and if end cell closures produce a soft opening, then it's A OK with me.

It's not a characteristic of Stilettos to do that, so I would guess that something is slightly out of trim. However, if it flys straight both before and after you pump open the end cells, I don't know if I would worry too much. There was an '80's canopy called the Unit that always had closed end cells and a hung up slider on every jump. But it was very reliable. I made 1000 or so jumps on them and never had to chop one.
