HELP AGAIN!

I built several coils for the Russian. Practicing. Finally got one at .5 ohms (the rest were above 1.5, I'm a newbie, sorry). So I said screw it, I normally vape at .5 ohms. I'll do this.

So I put it on, make sure it isn't touching the deck. And...it sucks .... Warm vape. ZERO flavor on something my zenith is giving me plenty of flavor on. So it isn't the juice.

And barely anything it coming out. And I have the adjustable airflow all the way open.
And it tastes horrible. Burnt almost. ...? I'm so devastated. I was so excited. It isn't working at all.

And for the first time in almost a mobth, I am so frustrated and ...... I want a cigarette bad.

Watch this video. Build it just like Phil does. Works everytime. FWIW. 0.5Ω is a little hot, even for me. Did you fire and compress the coil? Sometimes the resistance reads low before doing so. The coil needs to fire evenly from the center outwards.

Simple solution:
Your Russian is not one of your RDAs, and doesn't work the same as your RDAs. The Russian has a smaller vapor chamber than your RDAs. So don't expect the same resistance to work the same.

Your Russian will produce a very nice vape, but it's up to you to find the build that delivers what you want.

My simple trick that I use when sorting a new device is to always have a favorite vape sitting at my elbow while I do it. You wouldn't believe how many times that has kept a new kind of atty from ending up outside in a snow bank!

and I still like Wheelie's avatar :D

Yeah. I have temper problems already. I stole my husband's to vape on. The urge for a cigarette and not being able to have one was strong. One of my biggest triggers to smoke is frustration. And I'm plenty frustrated right now. Patience is a virtue I have always lacked.

Yeah, I did some research online and they said take the air flow screw out and just tuck it away sonewhere.

Sounds like a couple of things happening here. 0.5 is a bit low, IMHO, for a Kayfun (even on a mech). And I'm going to agree with the crowd saying you want to build lower for a mech than you would for a vv/vw mod. That said, ~.8 or .7 should be good. I run a Kayfun on my Slug at .7 and have had no problems. For me it hits the same as running a Kayfun at 1.2, @ 15 watts on a vv/vw device.

On to the burned taste.... To me this sounds like a wicking issue. How much cotton are you using? Are you making sure to wick your cotton to the deck, not into the channel, and not over the deck into the threads? Are you making sure you can slide the cotton cleanly through the coil (back and forth) without damaging it (while not having empty space)?

This is just my opinion (and I may get blasted for this, but I've tried just about everything and this is what I've noticed), but the Russian is less forgiving, in terms of wicking properly, than the original Kayfun or the EHPro clone. The most forgiving Kayfun style RBA (and my go-to recommendation to those new to RBAs) is the Lemo.

I went to my local vape shop, 2 minutes away. He toyed with it (didn't build it. I'm back at home and already ...... again). He said the same thing, to go up and that .5 is too hot.

He checked my build, and said other then the ohm being .5 it was perfect. Cotton too. But building on this thing is hard. And I don't know enough yet to know how many wraps yields what.

The 26 was too big. So now I'm using 30. Just did 9th raps with 30 on a 3/32 and it was 2.0 something. My battery can't do that.

30 watts in a Kayfun/Russian isn't typically going to end well, unfortunately. It'll be warm, and most likely, burnt.

Did you try any of the 1.5ohm coils you'd made? You might be surprised.

I had a terrible time getting my Kayfun working on a VV. Deepening the juice channels helped a lot, no more burnt hits. I hated building a coil and filling it up, only to find that it was time to drain and see what the problem was. It can be a pain, but you'll get it!

I'm starting to think me and the Russian are not going to be friends. I'm about ready to eject it over the balcony.

I use a Kayfun lite + on a mech mod all the time and vape NET exclusively. Air adjustment screw is removed and stored away. For me a single 28 gauge 0.7 ohm microcoil wrapped on a 0.52" bit is perfect and I use 20 amp batteries although a 10 amp battery would work just fine. Wicking is the key to obtaining the best flavor, if the wick covers the juice channel it WILL impede the flow. I use Japanese cotton and with cotton too much is....bad. Cotton swells when saturated with juice and if too tight the portion inside the coil can cut off flow and become scorched (burnt taste). When re-wicking I ALWAYS wet the new wick with juice prior to installing the chimney cap, that way (like a dripper), it's ready to go. After filled with juice and installed on my mod I cover the air holes with a finger and give a quick/light draw on the drip tip to "prime" the vacuum and wet the chamber. Careful though, to hard or long of a draw can flood it causing minor/temporary leaking from the air hole. Kayfun style RTAs can be a little tricky/fiddly but with experience comes reliable satisfaction. Dual coil Orchid V4s provide better flavor/vapor IMO but are even trickier to build right. Best of luck to you.

#/!& this thing. All the way to hell.

Built a .9 coil. Still warm. And you can suck the air in all you want. Barely any vapor. A whisper of it. Hardly any air getting to it.

And I took the screw out. Triple checked my wick making sure it didn't block the channel. Still crap.

It no longer tastes burnt. But it is the most unsatisfying experience I've ever had. Wasted so much liquid today.

DITCH the 26 ga!


to get the ohms you need your coil will be huge and you wont be able to clear the chimney top.


28 gauge kanthal is what you want although I'm having good luck with Nichrome 80.....

6/7 wrap and ... cotton....tuck the tails and vape on.

Is there a way to salvage my liquid to try again?

I usually use a syringe to to that.

So, with 30g, on a 2mm brace, you'll want a 5/4 wrap, one leg up, one leg down. Once mounted, dry burn and compress to be glowing even inside out. Now after that, thread your wick, pull wick ends up, set and tighten down lower chamber section. Trim wick 1/16th to 1/8th above the chamber top, wet the wick, and carefully tuck it down into the chamber, and mold it to rest against the positive and negative blocks, leaving the juice channels uncovered in an "L" shape. Test fire the coil, reprime the wick, put the upper chimney on, then assemble and fill the tank. This should give you a 1.1 to 1.3 ohm resistance, and be pretty good performance, if your juice is thick, you'll probably want the airflow screw in and tighten the air flow up a bit to get enough suction to pull liquid into the chamber.

Ok. So I took it apart after the advice it might be too far off the deck. And it is. So I put it 1 mm away, not touching but almost. It vapes a little better. Not as warm but still warmer then I'm used to.

And the flavor compared to my RDA is half. :(

But at least it is vapable now. Even if an annoying draw. When I'm out of juice in it again, I'll try a chimney build. Thank you all for your help and patience during my rage against the machine.

Edit to add: And the vapor production is better. Not great.
But better.

Much appreciation.

If the Russian is like a KFL in that the chimney comes off when you unscrew the deck here's what I do. If you have a plastic dropper bottle, take the dropper top off. Remove your drip tip and the dropper fits right in the hole. Flip it and put the juice bottle on it, now unscrew the deck and your juice runs right in the bottle.

As far as your 30ga coil.. Use a 5/64" drill bit, 8 wraps, perfect.

The Russian is not capable of delivering the flavor and vapor production of your RDA. The only Kayfun style tank that will come close, in my experience, is the Orchid.
