I just can't build. I am so bad I can't get anything right. I am trying to build a dual prebuilt clapton coil build and it was reading .4 after like half an hour of fiddling on my mutation x v4 clone, and took forever for them to glow and the flavor wasn't there.

Then I tried to get a build with just 26 kanthal and that was a total failure. The ohms were all over the place, could get it down to .4 like I wanted and it all was just a huge failure.

I can say, this whole ordeal has got me to just give up on all RDAs and just use tanks only.

0.4ohms is high for a clapton coil and 60W is not going to cut the mustard with it.

I would go back to perfecting the simple coil builds before you mess about with fancy-pant builds.

6 or 7 wraps of 26AWG per coil should be around 0.3 - 0.4ohms (I think) for dual.

My preference is spaced coils, but I am sure others would recommend contact.

Dude... 60w for a .4 Clapton is plenty. I run my .18 dual 26/34g arched fused Claptons on my Petri at 80w on my sig100w and they put out a ton of vapor. They're 7 wraps around a 2.5mm bit so they cover a lot of surface area and still produce plumes.

@Sanddeath what are the gauges of the Clapton you're using? 26/32? What kind of wire is it? Kanthal, N80, N60? Single coil? Dual coil? I can help you with your problems. The first thing I would check is if your post screws are getting loose on you after firing, the screws on my mutation x v3/v4 will loosen up after the first few pulse fires so I have to re-tighten them up.

ive ran clapton nickel wire at 25w and it vapes. I would try some twisted coils if you have a drill. Super easy.
+1
I agree, try something simpler and work your way up. I love twisted. Easy, and great vape. If you don't have a drill you can even use a pen. Some great videos on YouTube on how to do it.

So Let me get this staight.. Because you can't build a stupid uneeded fancy version of a coil you GIVE up..

You do realize that RDA can run the same type and style coil you have in the Tank. right. You don't need a "special" or Named coil to get a good vape. You need that coil to get , Ohhs and Ahhs from the crowd.
Ditto

They are using dual claptons at 0.4ohm, meaning two 0.8ohm clapton coils as opposed to your two 0.36ohm claptons.
So, if you need 80W to run your coils which are half the size of theirs then it is more than likely that they will need double the wattage (I.E. 160W) to run their coils effectively.
I stand by my initial assessment of the situation.

I Also use the mutation x v4 and my normal build in at least 5 of my other RDAs including my
Favorite at the moment the darkhorse I run dual claptons 24g nichrome wrapped with 34g kanthol (I make them myself) normal build is on a 3mm screwdriver and 5 wraps per coil and always come out to .22 to .23 and I have instant fire on a smpl with massive cloud production and flavor from button push to full potential is about a half second almost as fast as I push the button , what type of wire is your Clapton wire made with? I find that for claptons the best is a nichrome core as it heats much faster than my exact builds with a kanthol core And that is probably attributing to why your coils are in the .4 range also as kanthol has a higher resistance

For reference I can get the same production with the atty on my ipv3 at 40 watts ...going to 100 watts for me is too much

.15 cents vs $3-5 bucks a coil. I'd keep trying to learn

My guess is that they're not half the size of theirs, mine are probably bigger. I'm running dual fused Claptons, with 2 strands of 26g N80 wrapped in 34g N80. So in theory to run a dual .4 Clapton set up you'd need less power to achieve the same voltage since it's a single stand Clapton vs a fused Clapton. Im going to assume that it's kanthal which would raise the resistance over nichrome. The OP would be hitting 5.7v at 80w, while I'm hitting a comfortable 3.8v. So no, they would not need double the power to run them. I don't seen

Or consider the fact that that they're single strand Claptons instead of fused Claptons with two strands of N80 which is essentially a parallel build. They could also be 28g for all we know and wrapped on a 3mm bit, but still, I do not believe double the power would be required to run .4 ohm dual Claptons. On my derringer I'm running .35 dual fused Claptons. 2x28g N80, wrapped in 36g N80. .7 ohms each. 8 wraps on a 2.5mm. They work perfectly for me at 45w.
So going on your reasoning that 160w would be needed since the coils would have to be 14-15 wraps each to be double the size of mine doesn't really take in account for single core vs dual core Claptons.

For reference for my post above here is actually my mutation x v4 it's dual Clapton 24g nichrome n80 wrapped with 34g kanthol on a 3mm screwdriver this ohm'd out at .32 since I did 6 wrap instead of 5 on it and can be fired easily at 35-40 watts and can handle as much as you want to push at it sorry for crappy pic quality it's a pic I had on imgur from last month when I built it
