I built this two nights ago and have posted in other
threads but fits here too:
Built on the Rafale X
rda (Center T post is neutral). All Kanthal wire - 5x30g core wrapped in 30g fused with 24g using .4mmx.1mm ribbon. 6/5 wraps, ID = 3mm and has .8 ohm resistance. Ramp on my series box at full 8.4 volts is still pretty slow, but all of that wire holds the temp for a while so once it gets started it vapes big honkin clouds full of flavor
Another one I have that vapes amazingly is this beast on the Madhatter v2:
I can't remember the exact specs but I know it is a 3 core loosely fused clapton (there is a clapton and two twisteds in the core, I think) that triangled upon fusing. I almost chunked the wire but decided to play with it a little. I put 2 3mm screwdrivers together and wraped this thing into a figure 8 and installed vertically. Resistance around .75. This is one of my favorite series build so far.
