Vcore - vertical micro coil in oddy/kayfun/Russian/Ithaca/ect.

[JeremyR]

did a new rebuilt/redress on Russian. lets see how it'll behave now. took a few pics on the process that I'll post them later

Nice build D ... Let us know.

.7 ohms looks like 8 wraps of 28 @ 1/16..?
it's gonna be pretty hot you'll need ample wicking power. I assume you fully primed that filler before You tanked it. You may need more wraps. Take it up to 12 to 13 to balance it out don't worry if its more than an ohm.

Hey ocelot, sounds like you've got a pretty good build going. I find that when the flavors popping you have right tightness/ looseness of wicking around the coil. That's one of the hard parts of the build for me. So your half way there.

What APV are you using this on?

provari mini. I have tried all sorts of voltage settings. too high the throat hit and heat is too much. too low barely any vapor. I mean there is a good amount of vapor just not as much as my regular horizontal micro coil. I wonder if i make a smaller diameter if it would help?

here is the build before i wicked it.

 

[JeremyR]

Is that the same micro you use horizontally? Looks like about 12 wraps - is that your standard build? If so you may need to adjust the wicking.. Does it seem wet or dry when you fire it?.. you want a little popping not just sizzling.

So you cant find a happy medium in power.. Have you opened air flow control all the way? You'll need more air flow with these that will cool it down.

Looks like 1/16 and that should be fine. Any smaller and you'll be to 1.5, I think your pushing the provari already at 1.7.... I always seem to get better performance from higher ohm builds in the 2 -3 range on vv/vw mods.

 

[JeremyR]

To add to the vv mod and low res coils. The realistic amp limit is 2.5 amps with a single battery. Same as my zmax if I stack 350s I can get 4 amps. So 1.7 ohm @ 2.5 amps is likely yielding 4.25 volts 10watts to the coil. You can set it to 6 volts but your not getting it. A 2.3-2.4 w/30 would perform better yielding 6 volts at 2.5 amps @ 15watts. Heat faster also.

Going more wraps of 28. To increase ohms is going to increase heat up time

Well just did up a twisted 32, should be comparable to 28g. 12-13 wraps @1/16 for 2.3 ohms to max out the amp limit with one 18650 in the zmax v3. Wicked with hemp fiber. It's performing very well, better than the last 1.7 of twisted I had in there. I'm definately getting more power to the coil at this ohm level.

Still having a hard time trying to find the perfect wick wrap with cotton. More cotton = more vapor, less cotton= more taste but less vapor

Sorry to hear That. I have moved to a light pack since I'm using hemp. Now. Unless you get it just. Right. You may have to open up after ambit and add more / adgjust after the cotton breaks in. What atty gauge ohms vwraps and mod?

Russian 91 on a provari mini v2.5- 28g wraped 8/9 times on 1/16th drillbit with a 1.3ohm resistance

 

[JeremyR]

Well that's odd usially when to flavors pop its on, I haven't had less and more. You have the higher 3.5 amp v2 so are you hitting it at 15w 4.3v .. Well have I wait for dice the resident Russian user to chime in I don't have one. But you'll probably have better luck packing it so it looks like a carto; not too tight but god wick 2 coil contact

If you haven't done so already, try a parallel wire wrap with the 32. The coil comes out a tad longer which increases surface area on the wick plus I think you get more surface area wicking on the coil as well. Not really much difference but you might prefer one way over the other.

Highest I was hitting a 1.3ohm build was 4v and sometimes tried 4.1-4.2. Is vapor suppose to be more, less or on par as a horizontal? Initially tank after building it I get good VP but after that its just eh.

Yeah I've done. It lots of times actually last week bro, just did va twisted this time to get up. To 2.3 ohms .

Here's 1.7 ohm 32.

debating if i should give it another try. I want my clouds... but i also want my flavors

 

[JeremyR]

There will be clouds.. I did micros for about 10 months, kangers, then in the oddy for the last 6 months. 12mg nic for 10 months. Took it vertical like in the op and got a nic buzz in like 5 pulls. Intense flavor over what I was used to. Definitely something a lot stronger. I didn't get nic buzz from chain vaping micros w/ 12 before.

Its kinda like learning to use cotton, it took me a while. Then right after I got 40ft if silica .. I figured it out, and haven't gone back.

Some say cotton tastes bad, burns, or whatever, others say its great..

Sounds like you got a taste of it now if you could just maintain. IT does out out some serious clouds man, The nic delivery is proof of that... It can take some time to get it down, it's not the easiest build. You need some time and a backup to vape while you work.

Sometimes the cotton gets knocked off the coil by a juice pop. That can give low vapor and then off taste. Most likely that's what's happening. Its good at first then it falls off, because the wick fell off... I assume it's not flooding because obviously that will reduce vapor production as well.

For me it's working right when the coil is popping consistently not just sizzling. As long as it's not flooded either; you'll get a slight gurgle as the 1/16 fills with juice. In other words you want full saturation just below the flood stage. Sizzling it a coil thats too dry for this, if you do a wrap on the coil make it slightly loose, if its tight it will be choking off just like a tight coil on a wick.

I think you should try a pack to keep the wick tight on the coil. Also make sure you let it soak a while saturate it good take some pulls on it and drip a few times. Check the cotton to see if its collapsing anywhere and add more. A light prodding with a needle can show these spots.

I would go a couple more wraps like 12, that will bring it around 1.7 giving you full range of volts, being able to go all the way to 6v @ 3.5 amps & 21 watts.

You'll also need more air flow to capitalize on the vapor production. Open the a/c all the way. Maybe slightly faster draws than you used to. The draw plays a role in performance too.

Good luck!

ive been pretty happy with my twisted 32g regular microcoil on my russian with trumans wicking method (different thread) but as i just built a super nano coil in my RDA its making me consider a vertical super nano/nano coil on my russian. But with it being really small in diameter (used 28g kanthal as the diameter) the only way i could think of wicking it is vertically. Possible?

I have a turtleship mod now but i only use that to subohm. Russian is stuck to my provari like glue as that my daily vaper and on the go vape.

 

[JeremyR]

Its possible but difficult. The wicking has to be just right or the coil could fill up with juice. You may have better luck in that since the coil is above the deck out of the juice more than an oddy or protank.

 

[bingo6104]

I use a longer screw and a stainless tube to extend the neg screw on my 91% and it works great.
I tried to do this on a ehpro kfl plus and the chimney in the way, won't screw down all the way. It hits the screw.
I am just wondering if this is like this for anyone else. The chimney is not the same as the 91%

Yeah, vertical on the Russian is not only possible but gives a fantastic vape, the only thing better is a dual series vertical inverted V-twin build. And then use the Mundy Magic Twisted Ribbon wire and it just gets better.

You capture mundy wire under those tiny screws??? I tried capturing 24Ga under those stock screws and that was bad enough(too hot and not worth the effort). I bought replacement screws but they were the wrong size so they went into my trident clone. Those stock screws are one of the worst parts of the kayfun/russian experience.
