D-eagle Style Rebuildable Atomizer (6.5ml)

Nope, the older model had a glass tank also, read farther back in this thread where my second one's glass arrived broken and I modded a Kafun tank to use till they sent a replacement glass.

It may have been the plastic insulator right under the coils as that stopped a lot of folks from trying it.

The insulator was another reason I waited. Interestingly I thought that the older version was glass but its now listed as plastic. I just figured my memory was faulty. Sure wouldn't be the first time that FastTech changed a product description. But currently the older one is now plastic and the newer less expensive one is glass. That's the liner, for both the outer shell is metal with a sandblasted finish. Talk about making something confusing.

Well I ended up cutting that FT Kayfun tank down to 28mm with a 32 teeth per inch piece of broken hack saw blade then finishing the edge on sand paper on a flat surface. I'm vaping it right now.

It appears to be a crack in the upper left of the window but it's just the edge of the air bubble.

Thats awesome... should order a plastic tank at the same time I guess

I think maybe I understand now, the earlier version now comes with a plastic tank according to the description but mine were quite early and came with glass liners.

I have one and for me it is no better than kayfun. Not much more detectable vapor dispite dual coil. It is warmer but the vapor production is not significantly more than a kayfun 2om coil at 17 watts?

I have two, running the 0.4Ω one @ 40 watts and the 0.5Ω one @ 30 watts, I don't think I could push my Kayfuns that far.

I had mine at .07 and I could never take a kayfun even to that. My point is the vape is definitely hotter but not better IMO. On a regulated mod i build Kayfuns at 2.00 or above (12 wraps .28 gague) i am pushing so much power (20-25 watts) that it throws off essentially the same vapor. It is MUCH easier to build .04 was a much bigger deal when power was more limited?

 

[benriz]

I am curious. Maybe someone smarter than me knows. Does a sub ohm produce more vapor than regulated device at high power? for me it is the same?

 

[bsoplinger]

When it comes to vaping, power isn't power. That is, 50W delivered to a coil made out of 33 guage nichrome wire such as found in a Kanger Aerotank vs a 22 gauge coil in a RDA. The size of the wire, the material, the way its wound and wicked and many other things all contribute to the vape you get. So yes, if you build a sub ohm coil and use it on a mechanical mod or a regulated device you'll have the same vape. But if you compare the, as an example, 50W vape on the sub ohm coil on the mechanical mod and compare it to a 50W vape with your variable wattage device that has an Aerotank on it, no you won't have a similar vape.

Yea I can understand how a Kanger tank will not vape as well as a dripper regardless of power of the device, but what I am confused about is let's say we both have the same, RDA. You build a .03 quad coil and I use a single, 1.7 or 2.7 single coil at 100 watts regulated. What will be the difference in our vaping experiences? On a kayfun I can see a significant improvement at 20-22 watts over 15 (that until recently was the max for a regulated device). The mec mods give me a really hot vape (that i cant control) and a little more vaper. I like regulated because they are much easier to build and I feel I have more control, but again I have never been a great sub ohm builder and have only dabbled with mechs. I am lazy and regulated (AKA kayfun) appears to be the most gain for the least pain, but maybe this is because I don't understand and build sub ohm coils on mechs too well?

Prior to the availability of really high voltage regulated mods, I could see clear advantages to mechanical / sub ohm. Even though it was a lot of work the vapor as compared to a 15 watt mod was significantly more. I no a good sub ohm still beats a kayfun but the size of the victory now appears small????

 

[Midniteoyl]

The quad vs single is simple: The quad has more total surface area and lower temps per coil which equals more vapor with less chance of burning the juice.

Now, regulated vs mech is different. If the regulated can provide a smooth enough signal, then it would win over the mech, IMO, as you can go to a higher voltage than an unstacked mech, be safer than a stack one, and the newest regulated mods will even give you the same voltage as a stacked mech, only do it safer and for a longer period of time. Not to mention the whole 'regulated' part . With mechs, as you say, there is no control. You start at 4.1v or 8.2v and go down from there. Regulated mods, you can start just about anywhere you want and hold that voltage for just about the entire life of the batts. Mechs are sexy, but they are no longer the 'best', IMO.

I am with you on the lower temp per coil, but I know guys who are going 15 wraps on regulated? Does not 1, 15 wrap give me the same surface area is 3, 5 wrap? As you say the mec will still give more / better vapor because the temp on each coil will be less? In your opinion if I have 30, 50 or even 100 watts of regulated power available to me. What is the optimum coil size / gage for kayfun type tanks? In the old days (last year) it took too long for a large coil to heat up and they never got hot enough. Now, not so much. I am playing with coils and tanks but have not really found the "sweet spot" for a kayfun/ fogger etc? from .7 -2.8 they all appear to work about the same depending on how much power u give them?

 

[benriz]

As of today 28 gag 8 wraps (1.4 -1.5) at 17-22 watts appears to be the best I have found for kayfun and it's cousins, but the combinations available would take longer to try than building a mech with 4 coils hehehe

 

[Midniteoyl]

The 3 5wrap coils will heat up faster and still have less chance to burn as the center of the 15wrap coil will heat up first and be much hotter than the edges. By the time you get a good hit off the 15wrap, the wick under the center is dryer and hotter.

 

[benriz]

Yea I understand that a multi coil wrap will ALWAYS give a stronger / more flavorful vape. The problem for me is; I have to build, wick and re wick ALL of those coils and fiddle to go low, but not too low. No one can argue that multi coils do not give the absolute best performance, If u have the time / patience to do them. My question is; if ur only gong to build one simple coil on a tank and u have unlimited power, what is the optimum size?
