Coppervape's Skyline Clone

[Kusie]

Same here. The way this thing is build it´s logical that it floods after refilling if you don´t hold it upside down: when you refill, you close the JFC and open the top cap. After refilling, you have to put the top cap back on and press it DOWN quite a bit (at least 1 mm) over the nut to get a seal and be able to turn the JFC again. This generates instant air pressure on the tank. Now if you open the JFC again the only way this pressure can escape is are the liquid holes at the bottom, flooding the chamber. On the Kayfun V5 for example the top cap design us much better: the threads have holes to let the air get out while screwing down the top cap. The seal is made ONLY AT THE VERY LAST turn, generating nearly no pressure on the tank.

On the positive side, this thing has never given me gunky/dark liquid reflow and the wicking lasts forever. Been vaping almost 10 tanks with the current setup and still tastes great.

I finally am able to report back here that I have my Coppervape SkyLine and have run about 7 tank fulls thru it. With the glass tank that came with it I have no leaks, drips and very little condensate collecting anywhere. I changed out the o-ring for the JFC straight away. Am running mine with the smallest Air Disk out of the 8-pack extra that I bought from FT, 1.06Ω 6 wrap 2.5mm coil, 28g NiCr and 9 watts in power mode with KGD as wicking. I too notice a somewhat muted flavor, but very similar to my Lemo V1's flavor, so not bad at all, just not as Clear and Sharply defined a flavor as my DF Siren or CV Hussar. Juice flow back or darkening, YES, but I have no problem with that, as many others have already stated previously, It's an Non-Issue with me.

The only problems I have had was when I put the bubble tank on it, it leaked straight away. I took the Cleito Bubble tank off and measured the inside circumference to find that the Cleito tank was out of round by more than 10 thousands (.010) or 2.5mm, the bubble tank was just cut oblong instead of round, on both tube ends and would not seal properly enough to even get a good vacuum going, and refilling it was a disaster. I have a second Cleito tank I have not tried yet but will in the future.

I'm in the habit with most of my RTA's that have a JFC of closing the air flow, tipping the whole tank upside down then closing the JFC control, Filling the tank, tipping the tank upside upside down and when the small air bubble raises to the top (bottom) opening the JFC then the air flow control, tipping the tank right side up and screwing the tank back onto my mod. I get no gurgling or flooding at all, but that is just my habit of filling RTA's that have a JFC especially.

I really like my SkyLine and use it daily, along with my Siren, Hussar, and Toyota.

Nice shame about the poor quality bubble tank not sealing , mine has been good , maybe try the second one , it does almost double capacity [emoji106]

I am not quite buying that. I get flooding when opening JFC (not when closing) and it is pretty consistent. The reason I think is this:

(If image not showing: Imgur: The most awesome images on the Internet )

As you open the JFC the air between the inner chamber cap and the bell gets compressed and forced into the tank. This increases the volume in the tank. If you take off the base with the JFC closed, hold the tank upside down and open the JFC, you'll clearly see gurgling and bubbles happening at the edge of the inner chamber.

As for most (?) of you not getting flooding when opening the JFC I can't explain that. Maybe it has something to do with how often you open the JFC, the thickness of wick or something else related to how you use it in practice.

It would be very interesting if someone could repeat my experiment opening/closing the JFC 4-5 times in a row with the tank upright to see if you get flooding then. For me I sure did.

Personally I've come to terms with having to hold the tank upside down when opening the JFC (not only after filling). That is a doable workaround, but a major caveat and design fault IMHO.

Already done that 4-5times no leaks
opening closing maybe you got a defective or it just wicked differently to ours. ??
both are common with many other types/brands of RTA,s and users , this is why some like things others dont , some report leaks others dont,
Too much cotton mutes Flavours gives Dry hits too little it floods an leaks like all others

I too am of the opinion that what problems have been reported here with flooding are due to manufacturing and QC issues (dimensions on some parts not correct) and wicking issues, or a combination of both. As you say benley, this happens with almost ALL RTA's, RDTA's, and the more moving parts there are in a atomizer, the greater chance we see this happen. I might be one of the lucky ones with the one that I got to have no flooding, but then again, I only close my JFC to refill, then re-open when done, and I leave my JFC open all the time after that (I don't close my JFC when I go to bed for instance to keep it from flooding over night, then re-open it when I wake up).

 

[Marc411]

^^^ same here, so far flooding hasn't been a problem.

That's also where I got my Bubble tanks from Marc. Hope you have better luck than I did.

Yep, I saw your post and got them at Sweet Vapes. Since I'm in Chicago I normally get shipments the day after it leaves the door. I'll let you know how mine work out.

Interesting. Well, if I wick too tight I definetely get dry hits, so I don't think it should be any tighter than it is right now.

I have one from CV and the other one from FT. The odds for both of them being faulty are pretty low. Personally I think that the design is faulty, but it works in most cases due to usage pattern. What I need JFC most for is preventing leaking when out and about. I would like to be able to close it, throw it in my pocket, have it with me on the bike, in hot weather etc and not worry about leaking. When I have to hold it upside down when opening the JFC it becomes very inconvenient to open it just for a couple of hits.

I carry mine in my pocket sometimes forget to close JFc
Like i say only time mines leaked was wicking issue, use rayon in them now 2.5mm in one 3mm Clapton SS bud in the other , as long as i dont over fill them i dont have any problems after swapping that topcaps Oring over JFC works flawlessly.

Happens on my Taifuns , also , happens on all OBS tanks ive had billow V3 plus ,
Dark colours of juices happens to a lot of tanks , its all juices so dont really bother me its not something Skyline specific like i said happens on a lot if tanks ive had , OBS was worst ones crius engine , nano ect
Even my authentic Taifun mini

It's not really the discoloration, that's just a symptom, it's how fast the coil gunks up, I wish I would've taken a pic of that. It was gross.

On the juice discoloration issue, I wasn't having this problem until I started using my Churro juice from TBD liquids. Then, within the first few draws I would see dark colored juice entering the tank. Watched this video:

Was skeptical of the wicking method. But, man, if it didn't solve the problem. Worth a shot for others with same issue.

That's exactly how I wick it, though I always trim before I put them in, folding & stuffing wick tails like that always gives me muted flavor... when it was me using it I ran it at 400f and would adjust the jfc so that it was hitting right at 390 or so, that's the only way I got around my issues. My gf though does not like to run it like that, and she often just switches it to wattage mode if her coil gets too gunky for TC to work properly.

Mine is an authentic, it does the same thing.

strange.....my wife can't even get hers to flood....and that woman could bring a Tsunami to the Sahara!

I don't get the discoloration either...I vape Custards but I'm a chronic re wicker....usually every 2 days when I'm actually using it. No fancy wicking style, just folding the tails down until they barely touch the deck like every other atty with that style deck.

It's the 'nicest' atty I've seen in a long time...but I still think the Hurricane 1.3 and V2 has better flavor.

Once again the flooding that's happening is not perceptible while you're vaping it. You can't feel or taste it, but you can see the seepage after a while.

I thought it a doable deal, so I am trying the wicking method that @godfatherI suggested. I haven't taken my first hit yet (just finished building it), still sitting getting the wicks soaked. I'll let ya'll know what I find out though.

I was thinking about the JFC again an made this little simplyfied drawing:

Left shows the JFC closed, right opened. I think the crucial area is marked with a green "X". While opening the JFC, the air in this area has to go somewhere. And because of the seal (black) it can only go in the tank, thus the bubbles. The red area is the part of the JFC that increases the overall tank volume while opened but i think it's much less than the volume of the air that is pressed out of the area between the inner and outer bell/chamber. I'm still not sure if this will lead to flooding because the air is pressed into the tank through the liquid openigs inwards and not through e.g. the fill slots in which case the liquid would off course beeing pressed into the chamber.

Thoughts?

Thanks! Finally someone who's on the same train of thought as me

Like you I don't think the red area has any noticeable effect. As for the air coming into the tank when opening JFC, I did this experiment, which I repeated 4-5 times:

1) Turn the tank upside down
2) Close JFC
3) Turn the tank upright
4) Open JFC

That always leads to flooding for me, and I have done it multiple times.

As your drawing illustrates the JFC presses more "stuff" (air + juice) into the tank when opening it. This probably pushes the juice in the tank into the path of least resistance, which is the chamber.

The only way around this that I have found is to always hold the tank upside down when opening JFC. For me this is a major con since I can't use the JFC as an "on/off" switch for leak safe carrying. I mean I CAN, but it shure is inconvenient.

 

[soulseek]

In regards to leaking. I have very little cotton down the channels. If you look at pbusardos review of the Skyline, that is about how much I use as well and I never have any leaking issues.

Furthermore, I just got back from vacation and left the skyline with the JFC open when I got on the airplane. When I arrived I expected it to have leaked significantly had barely lost any liquid.

I'm not saying I'm doing something better than anyone else. But I suggest people use less cotton to begin with or maybe consider that they have a faulty unit?

Steam tuners new tank fits the insider build deck from billet box mod ,
Single coil , sold at silly prices 90£

Well, I just got back from the bike ride home from work, and one of the Skylines has leaked. With the friggin JFC closed. It hasn't leaked much though, probably just the juice in the chamber.

I'm not saying I'm doing something better than anyone else. But I suggest people use less cotton to begin with or maybe consider that they have a faulty unit?

I have tried all kinds of wicking methods, from those that gave me dry hits (too much cotton) to having an actual (tiny) hole straight into the chamber. The leakings I have does seem to occur regardless of wicking method.

I would love to be wrong about this, and discover some mistake I have been doing that would solve all my problems.

 

[Marc411]

Well I'm probably going to jinx myself but I received the Cleito replacement glass and built the Skyline. I'm on the second tank and so far so good. I must have gotten lucky because the first one I put on is round and so far dry as a bone. Have a second for backup.

I like the look of the tank with the new glass.

 

[52anddone]

I hear that Marc, it does look pretty good, at least to my eye. I'm gonna have to get another SkyLine just so I can try my second bubble tank on it.

LOL.... a perfect reason to pick up another tank!

 

[benley73]

Maybe find a tiny gold fish add it when refilling lol would certainly look different ,
