Frustrating for sure , as I want to get it and start building.

I'm just about to order from Focal and see that they've been on national holiday for the past week. They're going back to work Oct. 8 (HK time).

 

[52anddone]

Yeah, I know. For some reason I didn't see that they were about to go on a Holiday B4 I had ordered. Ya know, when a person is excited about getting a New style piece of vape gear, and have to wait longer than expected to get it.... It's surprising to me that I start feeling like I did when I was 10 years old, and being so close to a Birthday or Christmas, and how the hours seemed like days or weeks, then finding out that I was thinking it was Thursday when in actuality it was only Tuesday and I had to wait even longer ? I just hope that when I do get my Fev4, I don't feel like I did back then when I finally opened my present and found a pair of socks or a shirt and a pair of pants instead of the bright and shinny new toy I was hoping for. Just a small window into my soul at this point in time, I'm usually not like this, surprisingly.

I have a question , and I think I know the answer already, but I want to back it up with other FEV lovers.

A friend asked me if the FEV3 is a pressure or vacuum type of system. I think it isnt. It is the only rta I have that does not get affected by temperature or air pressure. I think someone said it was the only rta they took on airplanes because it did not get affected in any way.

Im I right or just blinded with love for my FEVs?

I guess in essence, FeV (I just own a VS) are pressure based. Positive pressure after we fill it up in effect, and negative when we take a drag. The latter creates an imbalance in pressure, resulting in juice drip into wick and then coil. I am not sure, but that's how I understand it.

 

[TrollDragon]

I would say it is a gravity fed RTA.

I was going to wait to see what the various answers that posted before I posted mine but I'll just go ahead and post mine now.
Same as any other atty where the juice supply is higher than the wick (not including squonker types)
Same, controled by pressure differential.

 

[anavidfan]

What ever it is, It is the only RTA I take out when warm and some else posted the only he takes on airplanes.

 

[52anddone]

OK, I think I understand the workings of a vacuum operated RTA (Lemo V1, Taifun GT-V2), but as I look at the Fev4 pictures (I am Still waiting for mine to arrive), I'm having a difficult time envisioning just how a Pressure Differential system works. I'll have to ponder on that little mind experiment for a while to fully comprehend. Today's not a good day for me and mine experiments I guess. I'm trying to think "Airplane Wing in Flight", but get stalled out.

Maybe you're "over thinking" the whole thing.

When first assembled there is a slight amount of positive pressure created by screwing the tank together. This is evident by liquid seeping out of the feeder wicks as the tank tightens up. The pressure, in the tank then equalizes. Once inverted, gravity takes over until enough negative pressure, combined with "surface tension", is created to stop feeding until the feeder wicks are low enough in liquid. At that point a small amount of air moves up allowing more liquid to flow down. If this were not the case liquid would leak out when the tank is removed.

A variable that would directly effect this would be the diameter of the center hole in the feeder wick. A larger hole would limit the effects of surface tension of the liquid and allow, true, gravity feed and, probably, over feeding and leaking. That could be overcome by having a dense enough coil wick high enough to effectively stopped the feeder holes.

Maybe I'm over thinking it...

Damn !! Looks like you might have a PH.D in Flash-e Science. Let me guess, from M.I.T. ??

I'll have to read that a couple of times so that it can have a chance to soak in, in hopes that I can understand just How it works so I can tailor the correct builds to get optimal performance, instead of just building to get by.

I've got my Lemo/Taifun/ErlK builds down pretty good at this point in time but, I see now that the Fev4 will be a different animal to work with and understand. Thanks for the description on the functioning of it for me (if that sentence made any sense to you ? ). I bookmark a LOT of posts that I don't want to loose (and yours is now bookmarked also) so I can go back and refresh when I have any problems.

I'm one of those people that HAVE to know How something works, drives my wife crazy as all she wants is for it to work.

My degree is from Seton Hall Institute of Technology. Note the resulting acronym, the real source of the degree.

Pretty good answer. All that is included.

The pressure differential is needed. It is vacuum that holds the liquid from pouring out. The effect of vaping it pulls on the liquid, breaks the surface tension and allows a little air bubble to Raise into the tank and liquid to Drip out. With out the air bubble getting into the tank you get no liquid feeding.. So there is an exchange of pressure.

So the amount of feed possible is set by the amount of open space in the feeder system for air to make it into the tank and the tightness of the feeders on the wicks. If they aren't touching enough it won't build surface tension and you could get a leak from jostling.

If I randomly need more juice feed I can Crack the tank to relive the vacuum and allow a little to come out or draw and blow to get a bubble to raise.

Good stuff, as always Jeremy. Thanks to you and awsum I'm closer to understanding, now all I need is MY FEV, and I want it NOW !! (watching too many commercials I guess)

Oh, Wait...... Focal says it's Shipped, 10-09-2016. Thank You Jesus.

Now that I'm getting close to picking up another rba tank. I'm right on the fence with the flashevapor. I've always been intrigued by the design. Does anyone have an update on the clones, have any of them been improved. Is the tobeco from 101 as good as any of the clones?

I was concerned with the distance from the coil to the end... So to make my tobeco oddy the length of the flash-e I cut a straw and slipped it over the mouthpiece; to make it equal the length of the flash. Holy crap *major increase in th and not really much cooler. If it is the th more than makes up for it! I think I can do the flash.

Yeah, another question Jeremy, this one's from you're post on page #7. I'm unclear on why and how you did what you did, but you said "Major increase in TH" and that got my attention. As compared to what ?? As you know, I'm ALL about TH.

 

[52anddone]

Hey Ya'll. Once it ships from Focal (china) about how long does it take to get to the States ?? I have checked their web site and tracking # and it keeps saying that "an error has occurred with the shippers web site" and to try back later. At least it shipped 10-09-16 @ 6:27 PM.

 

[Troll from behind]

Back in the days we used solid mesh wicks in our gennies (I kinda dislike calling ones like Avocado "genesis style"), but with FeV solid meshs don't work quite so well.
Capillary sumthin doesn't seem to work as well when liquid comes from top.

 

[52anddone]

My Fev4 is supposed to be "In Transit". If I like the "4" I'll prolly get a "3" also, or several more of each, can't have enough Good RTA's I always say.

Yeah, wow, back to pre- flash-e days.. I was originally concerned with the length of the flash. I was using an 'old school' atty, called the Odysseus, at the time.. I extended the Drip tip by like 2 inches with a straw to make it longer. A further distance from coil to my mouth. This made the th on that particular Atomizer stronger, that tank would be considered weak by today's standards.

Not sure if it would make any difference on other tanks. But a longer Drip tip may get you more th, I did find I liked using the long Drip tip that was included in Fev v2 kit, with dripper mode. I used it in dripper mode it was great, crazy long with the full tank. Lol.. Well then for that the kit also included the 8 ml tank set up. Lol
