Seems I have it running better. Coiled it on 2.5 with 26g, ohms out at 0.7. Very heavy on the cotton making
Sure juice channels stay open. Every time I vape I can see air bubbles come up, I assume that means the
juice is flowing. ☺. Spaced the coil wraps out and made sure the legs were even.

Flavor has improved with no burn taste at 22.5 watts. We'll see how it goes but so far so good.

Thanks for all the help!
Flavor should come on fully after a tank or two. Glad to hear you're back in business.

    I always find it takes about half of tank before get full on flavor after a rewick, but once got through that half of tank, I think the flavor is just as good as any RBT I've had, even the Aqua V2 which is known for great flavor is in the draw collecting dust since I got the subtanks.

    Seems to be doing just that. Im Up to 25watts after 1/2 tank with full air flow and good flavor.

    You folks are a great help!

    Thanks

    25w with the afc wide open? Good. See if it'll hang without dryhitting/burny on the 2-hole setting at 25w...the denser vapor production will bring on more flavor. If it'll hang at 25w keep turning up the power level a watt at a time for 5-6 pulls. The flavor will peak at about 3-5w down from dry hitting wattage. Nothing to lose...give it a shot.

    Thanks Nailz, you just saved me over $100. I've been saving for the authentic for a while... just removed finger from trigger.

    Yep, up to 27watts on the 2 hole and its got loads of flavor on my second tank.... Mo better!!

    Yes baby, this group is awesome!

    It my be the Blue Moon but, the STM is chucking the flavor and the vapor since I followed the guidance I asked for
    Here on ECF. I was beginning to think I wasted my $ and was just stuck with my Orchid RTA for flavor.

    NO, the Kanger Subtank mini is just awesome once I got the RBA COILED AND WICKED correctly. I'm very
    Impressed with it. Very easy to work with makes it a must have RTA.

    Thanks to everyone that replied to my request for guidance.

    good to hear.
    but u didnt do yourself a favor. u can throw your juice budget out the window.
    then you'll start thinking if its ok vaping all that juice in a 24 hr period.
    12 months ago i was vaping 20-30ml juice per week.
    now, i easily do that in a day, literally, damn u kanger

    Anyone have tried the new RBA section for subtank mini? The design is different than the original and I don't know which one is better but interested to know.

    Spit Back
    Anyway, I have spent around 2 months with STM. Most of my problem is juice spit back consistently especially with AFC wide open. I had tried to find several solutions while also trying to solve it on my own, but my findings:
    - 2mm coil will almost make the spit back gone but flavor is mute compared to 2.5mm. I never tried 3mm but I think 3mm might be too big for the deck
    - use a rotatable drip tip. Only issue is that the spit back will be collected inside the drip tip and you will have to blow it to a tissue to clear them up every hour or so. Flavor on this drip tip is similar with normal drip tip, almost no different but the normal one is still a tad better
    - use pipe screen. I fold them into 4 and the size would be match to 510 drip tips. Cut them a bit to make it round shape. This solution is the best so far.

    Dry Burn
    I am lucky enough that I almost have 0 problem with dry wick except when I was jamming the cotton too much. By habit, I don't really jam it so it is safe for me but I think the best way to avoid this is to use the leftover of kanthal (need a firmer one like 24 awg) to clear some space between the cotton and the juice channel. I think I saw this method in RIP's video and it works great.
    However, for STM, I found that it works great until 3.7 volts. Above it, even if I pour so many juice directly, it tends to burn. With my other RTA, it can perform at 4.2 volts so I think STM doesn't like high voltage.
    I don't mention the Wattage because wattage depends on your resistance. But the voltage measurement is stable reference.

    @cigatron Flavor came after 1-2 tanks?? That's scary! I re-wick after about 2 tanks. I re-wick every 1 or 2 days and that is anywhere between 1-4 tanks. To me, flavor came out after few puffs after re-wick and get muted after 1-2 days depends on how gunky is the juice.
    Boba's Bounty can gunk quite fast. NT's quite clean.

    That's all I can share for my STM experience so far. I am looking at Goliath or Billow V2 for alternative tank. Orchid V4 doesn't cut it anymore and perform much lower compared to my lemo or STM.

    um theres no jamming reguired, its not a kayfun build.
    i watched pbursado method for stmini, i did not work for me in one bit=total fail.
    my wick is in place and juiced up b4 i screw on the chimney

    i wick "somewhat" like .... kickers as i use a thicker/wider strip of deskinned cotton. here is his vid, 11.20 mark he wicks it.

    I've watched that but before I bought my stm... now since you remind me of this, I will try to rewick using this method and see what will happen

    Spitback? you're underwicked, under powered or have bad coil symmetry.

    Dry hits/burny at lower wattages? you're underwicked or have bad coil symmetry.

    Wicking only lasts 1-2 tanks? You're underwicked

    You're probably just underwicked. Try wicking heavier. 3mm coils are no problem in a STm (plenty of room in the rba). Wattage IS what counts, it directly correlates to the coil temperature. 30w of heat is 30w of heat regardless of the differing Voltage or Res values that got you there.

    I am quite sure that some of my wicking was very tight and it was still giving me much spit back... Anyway, on my next re-wicking, I will take a photo and ask for your comment and suggestion.
    Symmetry should not be a problem, my build is using kuro coil master and I re-position the coil for every new coil to make it right above the air hole and have a symmetrical axis.

    For 30W of heat is 30W of heat... I need to re-think... From experience, if I use let say, 0.2ohm and 30 Watts, I will get a cool vape but if I use 0.7 ohm, it might be too hot.

    At the moment my built is 6 wraps of 24AWG kanthal at 2.5mm dia which brings me around 0.49ohm. Vape it from 3.3V - 4.0V is very good (or 22-32.5W). Going up to 4.1V at 34W was a bit too hot and unpleasant and at 4.5V or 41 Watts, I got dry burn at the end of the inhale plus also scorching hot...

    With the pipe screen, at the moment I put 2 pieces cut to the size of the 510 drip tip and no spit back. But I can see that after a dozen of draws, the juice starts sitting on my drip tip meaning that there is still spit back but it is being caught by the pipe screen.

    @vincom .... kickers method is quite good... now I can vape easily until 4.2V with no dry burn... I can not go as high as his though. Maybe I just don't suck as hard as him.... I normally sucks a little only... not until my chest bloated like what his doing but it is much better now! Thanks for reminding me of that video

    This isn't entirely true. Different wire gauges have their own heat flux value.
    This is demonstrable by building two coils, same id, same number of wraps, one a 28 gauge, one a 24.... Then run them both at 30 watts... The difference in temp. will be noticeable

    Heat Flux (Thermal Flux) is a value which describes how FAST something heats up, not how hot it ultimately gets. So a thinner wire (higher res, less mass) pushed to 30w will heat up to temp quicker than a thicker wire (lower res, higher mass) pushed to 30w. It's still 30w of heat either way. What I said about wattage was accurate; just not the whole story.

    I like to run thinner wire at higher wattages for quicker firing times (higher heat flux). It allows me to take shorter pulls and save on battery life. It also extends wick life to a certain degree because the coil spends less time at "other than optimal" vaporizing temps where gunking is most prevalent.

    So yeah, you're right, there is more to our overall vaping experience than just wattage values however a wattage value alone tells us more about the vape than a voltage value alone or a res value alone when using VW mods.

    It would be great if everyone had the time to fully describe their build, airflow adjustment and vaping style every time they had a problem with their device but alas, most don't.

    Thanks for bringing up heat flux in the conversation......wasn't sure how technical peeps wanted to get on this thread.

    For those interested in coil building, including heat flux values, steamengiine is a great tool. Link below.

    Below is a link to steamengine showing my twisted 29awg spaced 6wrap build. Heat flux is in the green at 30w. Res is actually about .1 ohm lower than what steamengine calculates. I lung hit chain vape this coil at 30w all day every day with 60vg. 3 second pulls with the AFC on "2-hole" setting provides great vapor and "near dripper" flavor.
