Longtime lurker; RDA Advice

[n30nex]

I've lurked here for a few months and decided to register today. I stopped smoking cigarettes after 15 years to bring about a positive change before the birth of my daughter. I'm an electronics engineer so the natural movement to slow down or quit seemed to be e-cigs.

I got a nautilus premium kit and started with GoldSeal tobacco flavors that worked alright for a few weeks until I felt like I wanted more power and moved onto an iStick 30watt with a subtank mini. Now that I have begun to fall in love with the gigantic puffy clouds im getting with high vg juices.

Which leads me to now, I have an authentic black Troll rda by Wotofo coming on monday morning along with guages of kanthal from 20 - 30, a large swath of cotton and a coil jig. I got a 70watt IPV Mini II as my at home rig for the dripper and for the extra power.

I am looking for advice on what coil setup I should be running on this Troll for super-mega fluffy cloud awesomeness? I have built down to 0.3 on the subtanks rba but I know for this I will probably want to duel coil and much thicker ?

Also does anyone else here use cases? No one at my work does minus one with a Vaporshark DNA40.

I've got a Troll.... let me see if I have a build in it so I can post a picture.

Welcome friend. There will be lots of great advice to follow but i may as well get my 2 cents in while i can. I build .5 dual on my Dark Horse and get huge fluffy clouds on it while running it on a mech and a vtc4. Im sure if you slap a dual .3 or .4 in a dripper with regulated mod you wil be on cloud 9(yeah yeah puns are stupid).

Now when I do duel on a 3 post like the Troll, I'm trying to make sure that those two coils are as identical as I can get them? I know slight variation should not matter but I feel like I always messed up on a Chris Creations Fatty v3 2-post I tried at a b&m to see if I wanted to drip. The only coils I ever got to fire on that weird little dripper was like 0.8. Also I have a .... load of silica wick but I hear thats pretty terrible to use and I should stick with the cotton?

Here is a troll build:

ahhh and thats the chuff cap I kept reading about then. I hope my widebore from the subtank will not be too hot for now haha. Thanks man.

You don't need the chuff cap, its just a different vape and works really well when you are pushing a lot of power. I think that pictured build is 22g kanthal, which would work on your regulated mod, but you could also do the same build with 24g and would still be a great vape and might even work better at 70 watts... the 22g might need even more power than this. But thats a great build and works with many different gauges. 6-wraps around a 2mm screwdriver.

I use a 3 post system and yes i find it very important to make sure that both coils are as identical as possible. One leg longer than the other and that coil fires slower and makes one wick rub dry quicker than the other. Ive never used a troll but looking at davesignals pictures it seems like you will have 4 posts to work with...still important to have identical coils though.

Never understood why everyone tries to center the coils.
I leave them off to the sides using equal legs, And let the air come in across the coil face.

Same difference, the one benefit of doing that is the coils can actually get closer to the airholes without huge legs adding resistance. And once you get the coil centered in and almost on top of the inlets vapor gets thicker

 

[edyle]

use the steam engine coil calculator to work out your builds

since you are using a regulated mod, you can always adjust your mod to suit the build.

Because it is easy to do, and it is easier to wick. And it allows even better airflow across the whole deck. It is great for when you have a ton of power going to some massive coils that light up instantly and need the air to travel a very particular way.

Yea but think about it, coming in across the coil at an angle actually causes a vortex instead of smashing into the coil head on and then just going up to the exit

Not necessarily. In order to create said vortex one would need to have something pushing the air across the coil, otherwise the air will just go straight up as soon as it enters. I try to position my airflow such that the entire coil will face it yet the coil is slightly angled. This allows for the air to come into as much contact across the coil as possible.

It could be possible that if you build your coils such that they are raised higher than the airflow holes, and had them angled just right, you could potentially get a slight swirl through the chimney.

I think the air would move slightly vortexed either way, just due to the AFC cutouts. The air is coming in at the bottom and traveling under the coil. In the middle it is coming in at more of an angle and hitting the coil. And at the top, even greater angle, and above the coil. I don't like having wick under my coils. I want air not only to hit the coil on the side but also move directly under it right to and through the center post. Its harder to wick for that when you have a coil right on the edge of the deck... you kind of have to put the wick directly under the coil and end up blocking off that airflow.

But, you are right in that it can work great either way. I think putting the coils on the sides is simpler with higher gauge wire. But with an atty that has a positive post block, its really easy to put the coil in the center.... all you have to do it pick a different positive post opening.

If your using this on a regulated mod there is absolutely no reason to build extremely low. Just turn the wattage up till you like it.

Update.

26 guage because ran out of 24, and comes out at 0.5ohms. tastes really good and wow does it puff.

Thanks guys !
