RDA Dual coil build help

[BigLiquid530]

So I just got my Kennedy Competition rda and was going to build on it tonight. I want to get 0.5 ohm dual coil. My question, I'm using a coil master and was wondering what size would I use to wrap my coils. 2.5 mm or 3.0 mm. And how many wraps. I will be using 26 gauge kanthal. I've built coils before but haven't dripped in almost 2 years so been out of the game for a while.


Any help will be appreciated

8 wraps on 2.5mm
7 wraps on 3mm

What would be the difference in size, would 2.5 have better flavor less vapor

What would be the difference in size, would 2.5 have better flavor less vapor

not exactly. It would probably ramp up a little quicker, but the larger coil hypothetically would wick better.
Such a small difference probably wont matter though in this instance.

Well thank you I appreciate the help now it's time to start building

You may be running into temperature issues... it depends on what you perceive to be too "cool", acceptably "warm" - or "just right".
Is this on a mech, or a regulated mod? On a mech, the 26 gauge may be too thick for the 35 watts (and less) that Ohm's law parity provides. The vapor may be too cool, with only a 155 mW/mm² heat flux, at 4.2V.

27 (219 mW/mm² HF) or 28 gauge (311 mW/mm²HF) may be preferable... with a mech.

With a regulated mod, using 26 gauge... you'll need at least 46 watts to break into the 200 mW/mm² or more, HF range.

I'll be using my 150 watt sigelei

I'll be using my 150 watt sigelei

Then you're good to go, with what ever wattage provides the vape temperature you prefer.

What rda?
What mod?
And are you strictly going for .50 ohms
Assuming cloud chasing since sub ohms
Why not any lower?

I just like the vape at .5 its what I run my kayfuns at.

 

[BigLiquid530]

Guess I'm just use to it

 

[BigLiquid530]

Is it the less wraps the lower the ohms correct

 

[Lethal smoke]

Is it the less wraps the lower the ohms correct

Depends on the gauge wire and how big the coil like diameter

But what kind of cool you plan on making

all other things being equal, yes

Using 26 gauge kanthal dual coils trying get it at .5 ohms

Lately I've been wrapping all of my coils at 2.5mm, dual or single on a Coil Master. It's kind of become my general purpose coil diameter with 26ga wire. Not sure how many wraps but I'm running my dual coil RDAs right around 0.4-0.5 ohms on my dual 18650 mods. The nice thing about the variable mods is that the resistance isn't super critical, so if you are a bit higher or lower than your target you can adjust the output of the mod.

 

[BigLiquid530]

But I'm kinda curious, would lets say a dual coil, 24 gauge, at .5 ohm make more vapor the a 26 gauge, dual coil .5 ohm build

And what about flavor

The short answer is yes, because the 24ga coils will have a greater surface area with which to vaporize juice. You will have to run them at a higher wattage than a 26ga build at the same resistance to achieve a similar ramp-up time though.

Flavor, who knows. Depends on your RDA. You would think more vapor = more flavor but I don't always find that the case in real life. You may notice a difference and you may not, only way to find out is to try
