I am attempting to rebuild coils for aspire Nautilus BVC. I got the coil build down no problem, 1.8 ohm on my first build attempt ever. I wrapped the coil with organic cotton from a local (trusted) b&m. Filled tank and first hit was great, after that it floods and essentially turns into a straw and sucks the juice up through the drip tip. I left an air hole where I can see straight through the coil as instructed by riptrippers. I had my AFC all the way open. What's going on here? Attempted a KangerTech T3S coil, same thing. I thought building the coil would be the hard part. But I got that down pat. This is all temporary until I get a RTA or RDA. And speaking of an RDA, I'd like to use one on my iStick. I know it's only 20 watts and I can't sub-ohm which is fine. I'll be running a 1.5-1.8 ohm coil. I've seen people build drippers and use them on the MVP. Any suggestions on a good single coil RDA that is easy to build, just make my coil, run some cotton through it, soak it and vape away? Thanks. -Dave
