This RDA is TINY, how should I coil it?

I put cotton in it for a wick but the coil got messed up while doing so. A dual cool would be epic, but it's tight in here. I've failed at making a coil 3 times so far. What's the trick to it?

That looks just like the Smoktech RDA I got. How I've done it, is use 2mm ekowool folded in half and wrap 32 gauge kanthal wire around it 6 times... next time I'm doing five.. it registered at 2.6 ohms I want to be around 1.8-2.2 ohms. Then I moved all the coils as close as I could with tweezers to make the coils as close together and evenly spaced apart as I could. I then put the two ends into the little holes Positive and negative posts and tightened down the screws. Tested the ohms to make sure it registers. Make sure the coil is not touching the bottom of the base, wrapped the end of the wick around the screws and put some juice on. Then lined the airhole up with the airhole on the base. Not sure If this helped.
PS I tried a double coil on this RDA and it was so tight no air was getting to the coils. So I didn't do so well on that one either. I stuck with single coils and it's working again.

Look up mini squid. I opened the air hole a little bit. I have since moved up to bigger drippers. Bit that little thing rocks. I would do a micro coil with cotton in there. I usually make a 1.5 ohm coil with 28 gauge wire.

Thanks. It does have holes in the posts which is cool. It produces some decent vapor for how small it is! I drilled the hole, but I think I want to drill it a little farther. So I should buy silica? And what's a same ohm age for a mod? I think lowest I've ever run was 1.8 lol. I'm cloud chasin here.

Oh boy.. for the clouds I hear it's all about sub ohms.. but you have to be careful with batteries and many regulated mods like my MVP2 will not fire any ohms under 1 ohm. So I'm hearing the next best thing for cloud chasing is micro coils. Might want to look into that. You can get your coils to 1.5 ohms and it vapes like a sub ohm but you can use on regulated mods. well that is what I've read. Haven't tried it yet!
It's all about tastes. Some people really like using cotton. I haven't had luck with it yet. But silica appears to be the norm especially for those just beginning.

I tried the cotton tonight and it seems ok. Looks like I should try the micro coils. This is all an experiment for me before my vapemail comes in. I ordered a bagua and a trident. I hope I can figure this out! Stepped to this from a pro tank.

I would go with a micro coil. Since I started making micro coils, I've loved it. I run 28g 11 wrap micro coils at 1.6 ohms in my kayfun. You could probably do a 6 - 8 wrap with 30g in that RDA. Just make sure you torch the coil first. Hardens it up so you don't mess up your coil when installing it. Rip tripper has a good micro coil tutorial on you tube if you decide to go that route.
I'm hoping the bigger platform will be much easier to build! I have a phoenix V6 on it's way to me which has 3 posts instead of two. so it's designed to have dual coils. I think your trident is the same. I'm going to have to give the micro coil a shot, but I need to get a torch!
Very good info and thanks nova for the detailed post. I didn't know about modding RBA/RDAs until just now I just thought it meant the parts were replaceable!
I'd slap a micro, 1.2-1.5 ohms on that sucker if I were you, and save any sub-ohm adventures for your Trident. Real easy to short out on that cap with such a tiny RDA if you're not very careful. And I definitely wouldn't recommend a dualie.
You don't need a torch to get a good micro. Just wrap onto your drill bit of choice, keeping your wraps as close as possible. Install your coil and get a pair of needle-nose pliers ready. Fire your mech until the coils glow, release the fire button, and then as the glow is fading, pinch your coils *gently* together with the pliers. Repeat three or four times until your coils are touching and glowing from the inside out when you fire. DO NOT touch the coils with your pliers while you are firing. I repeat, DO NOT do that. And again, DO NOT touch the coil while you are firing. Trust me on this...

You can achieve dual coils by double winding...(wind 2 strands at once)
Just be very careful and do the math...
You can also thread in a coil from each side of the two posts.
Don't overdrain your battery or pull too many amps:
Ohm's Law Calculator
Never let the battery get below 2 volts...EVER. 3.4v or so is generally a good time to change the battery (it'll be lower than that when under load).
Your choice of coil type will have much to do with what size wire you have at hand, the size of your air-hole, and wick material.
You can get any of it to vape well...it's about balance between wick, coil, and air.

This is why I get intimidated. Lol. I guess for now ill go with a micro coil in it and mess with that! I currently don't have any wire. Or wick. That's why my next question is: what size and kind of wire should I get? When I tried to build a coil today, my problem was trying to not smash it while installing it.

Thank you! I just need more practice. This small RDA doesn't leave much room for anything but a single coil as I found out, the air doesn't flow around the dual coils pretty much at all! I'll wait for the bigger RDA to show up to try my hand again at a double coil! Had no idea I could double wrap a wire. But I really don't want to ruin my batteries. For me it's all about flavors!
If you want to do single coil micro coils in the 1 Ohm range 28 AWG is good. This stuff is pretty thick but has really low resistance.
Just as an example, you'll need about 2.5 inches at 1/16 wind of it to get in the 1 Ohm neighborhood and have some legs to work with. That'd be from 8 to 12 wraps on a 1/16 bit.
If you want simple loose 4 to 5 wrap coils, 33 or 34 is good...this stuff is really thin tho' so it will be tough to make a micro out of. These will give you coils in the 2.5 to 3 Ohm neighborhood. Easy and safe to work with...easy on battery life. This type of set up generaly works better for me with a 'small air hole' and tight draw.
For the more complex multiple coil stuff....remember that every coil you add will seriously cut down on the resistance and can 'double or more' the current drain on your battery. You'll probably want to first try regular coils with some of the higher resistance wire (32 - 34) if you really really want to try multiple coils.
Here's a vid showing a micro-coil method.
I usually shoot for the 1 - 1.5 Ohm range so I use 28 instead of 27, but that's up to you.
I don't own one of those jigs...I just use a hex wrench for winding.

I go with 28g and 30g wire for all my micro coils. For my mods that won't run below 1.2 ohms, I use 30g for the micro coil. If you decide to get a torch, get a chefs torch with the electric ignition. I got a torch I have to light with a lighter every time, and I regret it.
Just made my first micro today on a Smok Mini RDA! I used 32 Kanthal, 6 wraps around a 2mm screwdriver, ended up being exactly what I was shooting for 2.0 Ohms! Wicked with cotton and it vapes like a champ on my MVP2 at 6.5 watts! One very happy vaper blowing clouds!
