RDA Need some suggestion on issues having with first rda. Please?

[Mandy88]

Hey y'all.

i just got a cheap rda today to try out dripping and building. I'm already like #$&# this. It kills my throat, and I get more vapour on my evod

Unless I put the juice directly on the cotton, it will leak if I drip down the atomizer.

Any suggestion for a newbie or what I can do to make this better. I'm so disappointed, I was so excited. I got 2 little cheap rda's, I don't even know if they have a name, they were 50% at at my local store. They set me up and I was on my way, sometimes it works ok, but it's mostly so hot, and a really hot vape. I can't even suck for more then 2 secs. Is this normal?

One of them I got I can't even really get anything off it. It has a smaller air hole and is bigger then the other one, I know it doesn't help that I don't know the name of them. I've tried watching videos about dripping and researching but there is just SO much information it's hard to know where to begin.

Im using my istick.
The one that is working is set up with 28 kanthal and organic cotton. The other one I'm not too sure what it is set up with, I was in another store and they set it up for me.
I was using 100%vg, as well as 50/50 and 65pg/35 vg. I thought pg was throat hit, cause right now I'm feeling like I'm getting way more throat hit with the vg, and i even went from 12 nic to 3 nic with them.

But does it really matter the atomizer you have? I would think it's all about the build? i don't know if this post is pointless or not. I'm just lost.

Well if it's too hot, and you are using an istick, can't you turn the power down?

Mandy... it's OK to be lost and confused. Gotta' start somewhere, right? ;-)

Anyway... there are only three bits of information you've provided that are of any value at all... wire gauge, cotton wicking, PG/VG and nicotine percentage.

To diagnose your issue, we'll need:

• Specific RDAs... if you don't know, photos of the cap and build deck help.
• Dual or single coil builds.
• Net resistance. ("net" is the combined calculated resistance of parallel, multiple coils)
• If not net resistance, then wrap count and coil ID... or more photos.
• Other RDA wire gauge.
• Wattage of iStick.
• Sometimes, knowing the exact juice is helpful... some juices gunk up the coil/wick pretty fast and can reduce good wicking and thermal conductivity.

So... there ya' go. If you can figure out some of the above, or provide photos of what you can't figure out... we can help. Oh yeah... if you intend to continue, you need a Ohm meter.

Thank you

Ok, I think I got some pictures uploaded, hopefully it works! ( ok so pics loaded, but they looked closer on my ipad, hopefully you can click and zoom in)

My istick is showing 1.2 ohm for both of them. I have it at 3.2 V lol

As for the wrap count, sorry I can't see that close. I think the pink one is 12 or 13 and I thought they said they put 8 on the black one but it looks like there is more.

Juice is, Sovereign, mostly using this one. It's 100%vg

Anytime someone is having throat hit issues and is new to RDA's it's often an airflow issue.

Make sure when you install your topcap that the airflow hole is directly aligned with the center of the coil both vertically/horizontally.

Those RDA's are small so they'll naturally be a bit warmer, and they have relatively small airflow holes.

The caps are aluminum so you may be able to slightly expand the holes just by working on them with a paper clip etc.

Bit of tweeking and you should be able to get a decent vape out of them.

Best of luck!

Well for one thing, you need to put those wicks downwards into the deck where juice collects.

And I suspect you haven't paid attention to the airhole; you need to put the top on with the airhole lined up to end close to the coil so that as you suck the air flows all around the coil; otherwise the coil will just get too hot.

Photos are decent enough, along with measured resistance, to get an idea of what you have. Thanks.

Wrap count alone can be deceiving if you don't know the size of mandrel the coil was wrapped on... having the net resistance helps. To get 11-13 wraps of 28 gauge and see 1.2Ω resistance, means that the coil was made on a very small mandrel... about 3/64" (1.2mm).

With that small of a coil ID, there's very little wick inside the coil... juice is consumed quickly, even at relatively low wattages. You can have a perceived "hot" vape when there isn't enough juice to wet and cool the coil.

A 28 gauge single coil build at 1.2Ω, powered up with 9 watts (Ohm's law formula, where V² ÷ Ω = watts) has a cool, mild heat flux of 133 mW/mm2.
("Heat flux" is a value of coil radiant heat, expressed in milliwatts per millimeter of coil surface area squared... see 1st and 2nd "Steam Engine" siglines below)

As a point of reference, I run dual coil, cotton wick, sub-ohm RDAs at 220 to 350 mW/mm2... but my coils are typically built on a 2.5mm (a bit over 3/32") mandrel.

Throat hit, vapor warmth and flavor quality are subjective... and my builds are so different from yours, it's hard to make a recommendation.

Going back to your original complaint... I have a few additional comments.

• VG is "thick". With cotton wicking, it has to be "rolled" with only a minimum density. Too much compression restricts capillary action.
• Same with the fit in the coil... it should fit (dry) with only a slight drag.
• For that "long" of a coil, you need to take a bit of time between draws to allow the cotton's capillary action to replenish the wick-in-coil.
• Hard to tell from your original comments, but your air inlets may be on the small side. Not enough air will produce a weak draw with minimal vapor and flavor.

That's all I have I'm afraid. Without actually sitting at your kitchen table and trying out your builds, there's little else I can offer of any value. Perhaps someone else who identifies your build as their build, will come along and offer more accurate assistance.

Good luck!

What nic level are you using? When dripping you may need to lower your nic level. For instance, if you vape 12 nic in a tank, dripping 6 nic should give a better hit.
Don't give you on building lol. You'll find the more ya build the more you "want" to build! Ima girl who loves to try new attys just to see how difficult they are to build. If you haven't tried mech mods yet you are in for a treat lol. If you have questions hit me up and I'll do my best to help ya out.
P.S. Having different gauges of wire to build with makes life better too. Good luck and happy vaping

 

[Mandy88]

Ok great, all very helpful. It's just all confusing, but at least I know what I need to look into and educate myself on.

The guy at the store already made the air hole bigger, and I tried some too when if it home. Ippp

So if I get a better set up, it wouldn't be has hot and so harsh on my throat, is what I'm getting from all this. I just sick of wasting money on .... I don't end up using lol.
I'll keep playing around with it, but I'm sticking with my basic plain evod tank lmao, better then any tank I've ever tried

Yes, I did say that In my post I went from 12 to 3. I felt like I was gonna pass out with the 12

Follow the advice in above posts as relevant for all rda's.

Does seem like the wicks not being down in the deck and air holes not in correct position.

 

[ronnbert]

I believe the RDA is called the Squid and your unit is an vv3 not an iStick (unless you just used your vv3 to hold RDA for pic)

Yes I was just using to hold it. Sorry I was thinking after I posted that someone might be wondering,

No worries! Figured as much

Still having troubles?

 

[mcclintock]

From what I've seen, actually the intent is the wicks point UP not down. They may be blocking airholes. One version of these has an airhole in the deck itself, so no liquid there! This seems a flaw to me that the coil is being pulled around regularly.

I don't see a drip tip in the pictures, that would allow some chance for vapor to cool. They don't come with them, but should fit a standard 510 tip.

A local shop got a couple of these to try out juices, but I didn't get much vapor off of it. I considered getting one for a small flavor atty but there's got to be better. Still, should be able to get good results with it, although may need to drip every hit. Variable voltage can help figure if the build is too hot or cool. If you drip through the top, without pulling off the shell, may be able to drip more in without a lot of leaking.

I just sick of wasting money on .... I don't end up using lol.

When I started vaping I used to buy all kinds of stuff. Also touched on RDA's, which very quickly ended up in a drawer.
Now that I have been vaping for a few months, I revisit all those purchased items. And find them actually useful at times.

What I'm trying to say is, don't give up. Maybe take a break and revisit the RDA after you experienced, read and learned some more.

From what I've seen, actually the intent is the wicks point UP not down. They may be blocking airholes.

If you have the wicks pointing up away from the juice well, you are limited to the amount of juice contained in the cotton, meaning after one or two hits you are getting a dry, burnt hit.
