I usually build my rda to 0.2 ohms. I would say I'm a chain vaper and I constantly have to drip this thing. However, it seems like unless I give the cotton time to wick to the center of the coil the cotton will end up burning slowly. I've had this idea of wrapping the coil loosely so there is space between each turn, and when I drip on it the cotton will saturate through out very quickly. I'm sure someone else has thought of it and done it already, so I'm curious if there are any draw backs to this, as it seems like 99% of people wind the the coils as tight as possible and press the coils into a solid piece after heating it up.
spacing out the coil vs one solid piece?

It'll help a little bit. That's pretty much how they were built for a long time, before contact micro coils became the thing.
Other options are to use thinner wire (higher gauge) to make the coil shorter. Or using a larger coil diameter to put more cotton inside the coil, hence more pathways for the juice to flow. You can also try going to KDG cotton over cotton wool, it seems to wick faster.

That could work... but most people find you give up flavor when you do that also. Another thing is some people find the TH more intense with spaced coils.The key to space coils is making sure they are evenly spaced from coil to coil. Also if you are running dual coils you'll want them to be identical, not only in ohms but spacing as well. When you fire them you want the coils to all heat up at the same time rather than inside to the outside that you have with tight coils. IME with the spaced coils they also have more potential for shorts and hot legs than a tight coil. This is due to having to have the coils spaced evenly. The Atlantis uses spaced out coils so it's not a new idea. When the rebuildables first popped on to the scene; like before sub ohming and using high output batteries people used space coils all the time. One thing that I have found to help is to switch to KDG or Japanese cotton for your wicks. Honestly though I don't know if you'll see much more improvement by spacing the coils at .2 ohm. How many wraps are you doing? I couldn't see it being that many to achieve such low ohms. If you are using a mech that's 88 watts on a fresh battery. It's going to vape juice really quick at that power level. Dripping a lot and letting the cotton saturate is a must to get a good vape. Even with spaced coils you'll still get dry hits and burn cotton because you will dry out the cotton around the spaced coils fast. It may not take as long to saturate the wick, but you'll dry the cotton in contact with the coil quicker. Either way really you are going to be outrunning the cotton's wicking performance and it will slowly burn. If you want to vape at that power level then you just kind of have to be willing to re-wick more often and take shorter pulls while allowing the cotton to re-saturate between pulls. You build is kind of extreme to what I see most people vape at tbh. Most setups I see are around ~.4 and that runs around 44 watts on a full charged battery. If I was you I'd try to find a vape that satisfies you at a higher ohm and uses less power. I mean if the burnt cotton, dripping constantly, and letting the cotton saturate is something you don't want to deal with when you vape. Those things just kind of come with the territory when going that low in ohms. We could probably help you better if we knew more about your set up. There's a lot more to it than just the resistance of the build. What RDA are you using? What gauge wire are using? How many wraps? Single or dual coils? Parallel coils? Are you using a mech or are you running a regulated box? If you are using a regulated box what wattage are you vaping at? For example I have a doge and a magma with identical builds. Single parallel coils at .4 ohms using Japanese cotton. The magma is a much warmer vape and more flavorful. I run it at 30-45 watts and don't use as much juice. If I go over this level it just gets too hot. It doesn't taste burnt, but it's a hot vape. The Doge on the other hand with the same coil and wick and it isn't nearly as efficient as the magma in wicking, juice consumption, or flavor. Yet it is seeing pulls anywhere from 30 to 100 watts and gives a completely different vape. It's much cooler even at higher wattage levels, a lot more clouds, and less flavor due to the increased airflow of the Doge.
If you're looking for a way to wrap coils with very slight but even spacing between wraps I've heard of people having good luck wrapping around a machine screw. Just stay between the threads and you'll get perfectly evenly spaced coils.
Should be enough of a gap to help stuff seep in through the coil rather than just in the ends of the coil.

VapoMike I'm curious as to what gauge, ID and number of wraps used to reach your .4 single parallel coil?
