ok folks, i have returned from the dark side(subohming)and glad i decided to use 0 nic juice to conclude my exploration. i have done five different builds for the helios since friday. the whole idea to subohm really stemmed from my desire to use some 28ga wire on a build. i had regulated mods and egos for power sources so subohming was unachievable. last fridays mail brought a helios rda, kayfun 3.1 and an ohm meter. after i broke the center pin on the kayfun, my attention turned to the helios rda. still didn't have a mech mod and i did a 12 wrap coil with 28ga to get 1.7ohm and fire on my vamo. had to throw 12 watts to start and allow a second for it to heat up all that metal. then it would pop and start to sizzle. i was floored by the vape, throat hit and especially the flavor this atomizer produced.
saturday, my mech mod arrived and i did a simple 6 wrap contact coil with 28ga for .8ohm. basically, same great results as i got before except it heated up with very little lag time. i tried two multi-stranded wire coils builds. the first, ln post above, was a beast. took forever to heat up, and i thought i was going to drown from all the vape it made. could not handle it as the vape was too warm, 9mg nic was making my eyes gloss over. decided to tone it down with 0mg nic. and made a clapton coil with 32ga over 28ga. i do it different from rip t. and chuck 6" of 28 with a spool of 32 and made what looks like a d-string much easier. i got a 1. ohm build which made me feel a bit safer but it still took a while to heat up and produced very dense hot fog. more than i can handle!
i don't know how anybody is able to take a direct lung hits like you see in videos. their throats must be totally desensitized. i was a menthol smoker and somewhat desensitized by single draw straight lung hits. the multiple mouth to lung hits
evolved from trying disposable e-cigs 6mos. ago.
still overwhelmed, i went to a single 28ga 5 wrap on 3/32" and spaced the wraps. got .9 ohm. the larger i.d. allowed a nice piece of cotton without binding and i can manage the vape it produces. no lag time heating up, sizzles from the get-go. flavor awesome and only a slightly warmer vape than what i'm used to.
here's the rub. where is all this enhanced vtf coming from? the wire 28ga. or the atomizer? when i first started making my own coils i bought samples of 32 and 28. couldn't do anything with the 28 so i built 32ga coils with cotton for my kangers. three feet doesn't go far and i ordered 100ft spools of 32 and 30ga. a couple mos. back. the spool of 32 didn't get touched until i used it to make the clapton coil yesterday. 30ga allowed me to lower resistance to what would still fire on the vamo and it increased vtf a great deal over 32ga. just like i am experiencing, with the larger 28ga. now. i am concluding it is the wire and will try a 32ga build for the atomizer to know for sure. stay tuned to this thread for the upcoming conclusion.
