First RDA

[kittyvape]

Hiya 

Ordered a CLT v2 (upgraded version) from FT. link Soooo easy to build, but am finding it gets very hot (too hot to vape) plus hardly any vapour. Are you supposed to just drip new flavours down, without taking off the case, as the case is too hot to keep removing? I find it a difficult way to inhale too, takes a lot of puff, lol. There looks to be plenty of vapour possible, when I just fire it without the casing on. Had only done single coil builds before now, but was very easy to fit the 2 coils in this case (Ruby Roo's vids are great), and it's showing 0.2ohms. I usually vape around 24-26w. Unsure if I'm meant to raise the watts a lot or something.

First RDA at 0.2ohms raises alarms for me right away.

Do you need to go so low?

That ohm limit is pretty advanced and pretty dangerous even for advanced users.

could you try building a bit higher using steam engine www.steam-engine.org/coil.asp?s=dp&r=0.5&dia=0.42&id=2.5

are your air holes open enough, never known a draw too tight to puff on an rad like this one.

without wicks, were the coils heating up evenly with no hot spots?

cotton could be too tight.

maybe add a piccy

Sorry to nag, just trying to get you to be safe as well as stinky free

Thanks Tom   I'd been a bit unsure about the ohms so low. I'd put in 2 pre-made 0.5's that had arrived in the same post, just for convenience, but have some 24 guage wire. Have only used that so far, for 0.5 single coil builds, although have some 22 guage on the way, in first order from Focalecig. Thank you for the link ... will get to work and recoil/rewick, plus check the present cotton and upload a piccy. Not nagging at all; appreciate advice very much.

Cotton is looking a bit weedy, lol, even though I'd piled loads of liquid in there. (sorry for fuzziness). Have removed cotton now. When fire up, one coil is slower to light up. Air holes fully open ... even with that, felt lungs would collapse. With air holes closed, even more difficult.

You need longer coil legs to the negative posts kittyvape. You should centre them more. Also the coils look too low on the deck. Can't really tell from the pics, but they need to be level with the air flow slots/holes. That cools the coils.

And you could get a heat sink adapter to help as well. www.fasttech.com/products/0/10010809/1998904-510-heat-dissipation-heat-sink-for-atomizers

just cos it can take 2 x coils, you dont need to fit 2 x,, you could simply fit one 0.5ohm coil and vape away..

When you re coil, use post 1 and 3 for one coil, and 2 and 4 for the other. This helps centre them.

Also, what phatfil said. (But ignore him , it takes dual coils so put in two 1 ohm coils for 0.5 ohms)

[*-SARIN-*]

It looks like you've put the coils in posts 1+2 & 3+4 when they should be in 1+3 and 2+4 so that the coils are in front of the holes - this is not be helping the heat situation. Ohms that low need a ton of airflow to cool the vape, as others have already stated you might try starting at higher ohms cos the questions that you are asking indicate that you don't know what you are doing. Sorry to be blunt but it's better that than lose some fingers. Don't go anywhere near the 22AWG, you'll be at seriously low ohms and the dangers increase rapidly nearer the super sub-ohm levels. The airflow NEEDS to be fully open at these resistance levels or the vape will be like lava, especially if airflow isn't set correctly. Wicking needs to be right, not too tight, not too loose and don't expect to be taking long inhales any time soon, short sharp bursts until you get used to it. IMO the CLT is an advanced cloud chasing RDA and not suitable for first time users but as long as you're utilising safe battery practises then it'll juts be a case of a bit of tweaking and getting used to it.

Built the 2 coils again, but I've done it wrong, as it's come out at 0.3ohms. I can see what the problem is, as coils are not heating from the centre, but from one side, due to post-wire at the other end slightly overlapping the coil. I can use 1/3, 2/4, instead of side-by-side posts, as long as one is positive and one is negative?

Yep....the 2 in the centre are positive.......the 2 outside ones negative

Thanks tim   Sorry, the negative posts are the outside posts? Thanks about link. These are too low?

Thanks *-SARIN-*   Sorry, answers are crossing over, as I'm not reading down first. No problem; appreciate advice. Going to rebuild now using 1/3, 2/4 (had followed a vid, eek), and avoid 22awg, keep airflow fully open, and sort about the heatsink. Will ensure wicking better too and stick to short inhales. Using the Sigelei 150w, max at 40w, so am glad it has the inbuilt protection, plus using Samsung 25r's. Love the Kayfun 4 clone best, but great to learn stuff now via RDA too, as long as keep safe, definitely.

its coming out at the right ohms because your using 2X .5 coils so the resistance is halved so it should be .25 ohms

your not setting the coils up quite right as you want the coil in the middle
use the other positive post and leave a longer leg on the neg(will need to bend it to shape before fitting)

best pic i could find but you should be able to see what i mean(ues a hole miss a hole use a hole)
make sure the coils are lev with the air holes in the top cap(hold them side by side to check ;p)
check for the glowing from center and tweak with tweezers till happy
wicking is use as much as you like but trim it so it rests on the deck ,dont stuff it under the coil as this restricts air flow
juice up and enjoy

just to be clear because your using 2 coils there resistance is halved
2x .5 ohm coils =.25 ohms
2x 1.0 ohm coils=.5 ohms
2x1.5 ohm coils =.75 ohms
ect

hope that helps

perfect decoy Thanks!  Doing that now. Not sure how to get a 1.0 coil, as, when I change details in ref chart, it says 18 wraps.
