I just thought id pass along my experience for all you Russian/kayfun users as to whats worked best for me. I know opinions are like a******* :D

I have tried some dual coil builds, but there is so much wire that it ends up taking forever to heat up on the mvp2. Ive tried 28 guage single coils, and again for me its taken too long to get a good vape going. 32 guage hits quick but seems weak, and the coils dont last very long. 30 guage seems to be perfect for the MVP2, but again this is subjective.

Ive found the key is hitting around 1.5ohms on a 30 gauge coil. Ive seen many here (including myself for awhile) roll a coil similar to this (not my picture):
photo-3-jpg.2381


However, recently Ive been building them closer to this (not my picture):
239586d1375922132-kayfun-lite-wick2.jpg

...and its been giving me a much better vape. One difference is that I space my coils out (instead of wind them tight like the 2 above) so they dont gunk up as fast, and so the wick can "press" in between the coil wraps and thus produce more vapor due to more coil/wick surface area.

I call the latter picture the "angled" coil build. It has a noticeable advantage... Do you notice the legs on the first picture? That is resistance and thermal mass that isnt doing anything (because it doesnt contact wick). If I wind a coil like the second picture I can get another wrap in the coil (8 instead of 7) while keeping the same amount of wire and the same resistance. As an added bonus, do you note how the wick sort of "wraps" past the screw and then back towards the deck (on each side)? For one, you can get the wick up against the coil wire all the way to the screw (as it wraps around back towards the deck), and there is more wick to hold juice so it seems to chain vape better. I have noticed that this setup works really well on the MVP as it maximizes the (relatively) limited wattage the MVP pushes.

Im sharing this more for the fellow noobs in the thread, not for you experienced guys who know all this stuff already :p Any comments or suggestions welcome :)

I will. I didnt even know different types of wire heated faster than others! Ill let you know how it works out :D

.......talking about and recommending "Nichrome 80 Wire" below.......

28 ga Nichrome 80 should be fine for your KF/Russian.......the Nichrome 80 seems to burn pretty hot & heat very quickly,

i use 30ga mostly for my higher resistance small RDA builds like the BT-801 on my MVP.......yet 26ga also seems to work great on my low-sub builds on my 26650's, instant clouds and for my 22mm attys i use 28ga........you might buy some 30/28/26 ga for your different atty's & builds and that should cover it all......25ft rolls are very reasonable.

I dont understand what you mean... who are you talking to (me?) and what is "nr-r-nr"? By toppers do you mean Russian/Kayfun?

Gonna need some clarificationz :D

Sorry Jandry, I was speaking to you both/either

about whether you dont need to use

none resistance - resistance - none resistance wires for constructing the coils

in the kayfun type rebuildables

Nichrome 80 is low resistance wire, if you go to lightning Vapes you can check out the specs :)

it covers more area and heats quicker than Kanthal, great for low or high resistance coils.....i been using it exclusively now for awhile and i'm very satisfied w/it; just my :2c:

also works very well with 30ga with RDA's on the MVP, no need for the ole double-tap.

What does the double tap do?


the double-tap is a method of getting extra vape time on the MVP, some folks who use Kayfuns or drippers with 28ga kanthal or so wire get cut off after the ten second time limit and don't get a good amount of vapor, so the double-tap is simply hitting the button for 8 seconds or so then letting off and re-tapping the button again....when you do this the coil is still hot and picks rite back up to get the rest of your vape on :vapor:

Ive tried to respond to your question, but ECF has kept telling me the "token" is expired and that I need to reload the page... (??) Heres what ive been trying to post:
"Nope, you can use straight resistance wire screw to screw. Wicks are generally silica, cotton, or rayon. Silica scares me for health reasons, rayon works the best but it also sort of scares me for health reasons (though its prolly fine), and cotton seems safe but doesnt chain vape as well.

The point of the RBA's is that you can rebuild them without having to have any special parts (silicon grommets, etc), and that they enable you to do many different coil configs due to the added room. They also produce great amounts of vapor (due to room for good coil configs). You can get some kayfun clones pretty cheap; the Russian is about $100, and the original Kayfuns can get really really expensive. "

i saw a build a dude did without any wicking material, it's here at ECF somewhere but i can't find it for the life of me, he built his coil almost touching the bottom of the deck like 1/2 mm and it roasted the jooze just fine and got a good vape....if i remember correctly the coil was sorta angled t words the bottom of the deck.....just throwing this tid-bit out there to ponder.

Another way to get your nicotine with the thicker guage wire is to have "vape sessions" as I like to call them. Basically, you do your first hit (which is weak since the coil has to heat up), then shortly after do your second hit. Then not too long after, do your third. Then your forth, etc. You basically chain vape for a session until you can tell your wick isnt really delivering well, then stop to give the wick time to soak up more juice. Then repeat.

How many hits you can take depends on the wick- silica and rayon wick well, so you can chain them longer before they start to get behind. Cotton hits real strong (prolly the best), but its best property is holding liquid, not wicking liquid.

Does this make sense to anyone? Not sure im being very clear..

Do you not have to bother with nr-r-nr type coils
on those toppers ?

It's really not need on any. A few complain about the rubber grommets burning, but I've not seen the same complaint with silicon grommets. A lot depends on what resistance and power you use, along with how long you keep it hot.

I have 1yr old rubber grommets that are getting hard, but no bad taste. Always straight Kanthal in them.

Ha! Thats a great idea. I think I might seriously give that a shot...

yep it makes sense, let's call it double/triple -tap version#2 :D

PhilB has put up his review of the iStick. Nice little device but not an MVP killer IMO. Nice alternative or backup but not a replacement. I would still recommend an MVP to a person looking to move up from a starter kit.

I suspect part of the MVP 11 watt limit is because at the time of release, it was a safe amp limit for the battery pack. In the short time I have been vaping, 18650 amp ratings have gone up and up. The MVP 3 may get a boost in watts just from the battery technology advances.
