Don't have the Aerotank or a full-size Protank2, but I do have the mini PT2 and some kayfun clones (lite, 2 minis, 3.1ES) Jandry, I'm so with you on "burning wicks and swearing at it"
Truthfully, I'm pretty happy with rebuilt heads on my EVOD tanks - I get good flavor and enough vapor to amuse me.
+1 on "impossibly subjective". I guess part of the "quest" is to find what is best for onesself
Enjoy the
Yeah, especially after rewicking and rewiring the Protank 2 heads, ive been surprised at how well they vape. I bought the Protank as a backup figuring id like the TDC iclear; it worked out completely the opposite.
Jandry, don't know if this will help much or not, but I've been finding that the 1/16" bit might be a touch too small for my kayfun decks. I have used one of the mini screwdrivers (NO idea what diameter) for a slightly larger coil. I've snaked the cotton like RipTripper has shown in his video; I've snipped the ends flush with the deck (as you show in your picture); I've done "bunny ears" and then tucked the primed wick back into the chimney base. My 3.1ES has BY FAR the best configuration. It's very airy, though, and it seems like I'm guzzling juice in that one (it's about 2.0Ω, and I've run everywhere from 8.0-10.0 W on that bad boy.) I've tried donesmokin's rayon and my normal cotton.
I also try to make sure there's some room between the coil and the air hole on the deck. Basically pry up the coil and make sure I can fit the mini flat-head screwdriver between the coil and the airhole on the deck. I had one of my minis rocking my world (absolutely no vacuum issues) and then I had to rewick it

Now it bites, and about every 4-5 hits, I have to repressurize it....
When they RBAs work, they're AWESOME. When they don't, ya wanna just throw 'em.....
Thank god for spare tanks, so at least I can keep vaping while I'm cussing a blue streak
We'll get there!
:edit: One other trick someone else taught me here - if you have to "dump juice", get an empty bottle and unscrew the base. This releases the vacuum and allows the juice to flow out the tip into the bottle. I've saved at least 1/2 tank each time I've had to futz with the wicking.
I will try going slightly larger than 1/16th with 30 gauge. As long as I hit 1.4 ohms I should have enough room to hit my desired wattage. I vape around 9 watts, so even if the 1.4 ohm means I hit the MVP's amp limit before 11 watts, it should give me 9 watts just fine. I cant imagine going larger than 30 gauge because of heat-up time. I have considered going 32 gauge dual coil, but I need to work out this Russian problem before I start messing with that.
+1 on having a good spare tank. The Protank has been my go-to and has given me almost no issues- no leaks, dry hits, etc. I did get some flooding with 60/40 juice when I went too light on wick, but that was easily fixed and my fault. My only issue is that I dont have a spare mod. So anytime I want to try something, I need to switch tanks on the MVP. Another MVP or an SVD is my next vaping purchase for sure. It seems the upper level 30watt mods and such are much more unreliable, and I think anything over 11 watts would be lost on me. On the other hand, the SVD allows a higher ceiling.
I had issues with my Kayfun at first , to be honest your build looks fine and should work . Cotton expands so if it's overly snug in the coil when your setting it up dry hits will likely be a result once juice expands it further. The biggest change for me with the Kayfun was when i really opened up the airflow , wow what a difference it makes , like night and day .
Correct me if im wrong, but increasing the airflow at the airflow adjuster or raising the coil height will inversely affect vacuum on the juice channels, right? I love airy draws, but in an attempt to get some working configuration, Ive cranked down the air adjuster a bit to add vacuum at the juice channels. I hear you on cotton- I have gotten the amount of cotton down on my Protank coils which work perfect tank after tank- and im using the same size coil on the Russian as I do on the Protank heads.
I definitely look forward to getting the Russian hitting right; it works great when it works.
If your going with an Evolve board i would just pay the $50.00 and get the whole deal even if you have the charging part , the Evolve DNA board has been difficult to get at times and your probably going to pay right around the same whether you get the board with or without it .
For $56.00 you can get the Fasttech DNA V3 model which has received great reviews and it even comes with a great quality battery , the early Fasttech versions got mediocre reviews but the latest are excellent .
By going this route you get a great quality box with the latest finish (finish is very impressive by the way, a friend has two ) and the latest chip , if you like the way it performs you can just buy the chip and put it in your other box and you will only pay twenty something bucks instead of fifty plus.
When i ran my Kayfun on my MVP i got resistances ranging from 1.5 -1.9 with 28 gauge but i noticed if you limit the coil diameter to 1/16th and no higher the MVP provides a great vape .
When i tried larger diameter coils on the Kayfun and MVP it did not work well because of the slow heat up and a quick MVP shutoff time , 1/16 works though . I actually have tried all different size coils including 1/16 , 5/64 , 3/32 , 7/64 and even 1/8 and to be honest i do not see any vape advantage with the larger ones even when using a higher powered device .
With the MVP i always go no larger than 1/16th with 28 gauge but if you use 30 and 32 gauge you can but again i don't see any real vape differences.
I don't really like 32 gauge because of two things , the first is it's too thin and breaks easily ( and will spring loose from the coil if you let it slip and entangle your body lol ), secondly, it doesn't provide enough coil surface area , your typically at your preferred resistance with as little as four to five wraps instead of eight or ten with the 28 and 30 gauge.
Supposedly the more coils that make contact with your wick the better the vape , four or five very thin 32 gauge coils have very limited contact area .
Ironically, I get the best
overall experience on my Protank coils with 32 gauge 6 wraps. Running 8 wraps 30 gauge seems to take a LONG time to start hitting well- say 4-5 seconds. On the russian, Ive used the same 30 guage 8 wraps and it seems to hit faster; the only thing I can think of is the chimney design? It definitely produces within a 1-2 seconds. It must just be that the whole coil area is more substantiative than the Protank coils. On paper I would swear its my imagination, but I can literally prove it doing a side-by-side comparison.
Time for some outside help? A Yelp search of Austin shows a bunch of vape shops. One guy talking about Amp Vapor got his Kayfun going for him.
I bought the Russian from All About Vapor in Round Rock, so ill prolly take it back and see if they can provide me with guidance. I could have saved 10-15 bucks buying online (maybe, considering shipping its prolly less) but I figured Id support local business. Hopefully theyll help me out
While im no expert, it seems to me I understand how it works. At the same time, I must be wrong because it makes no sense to me why a 60/40 juice wouldnt feed when I have low airflow (for increased vacuum), a low-height coil (for more vacuum), no obstructions over the juice channels, no leaks, a clear path from external airhole to coil airhole, wick configurations ranging from too much, too little, "perfect", etc. The only thing left is slightly bigger coils with less wraps, trying Midniteoyl's wick design, and possibly whatever it is that im missing.
Ill let you guys know when/if I figure it out. I appreciate all the help and apologies for the novella response
