Subtank air flow base problems

[sleedale]

Curious to know if anyone else has this problem?

i have tried and tried and better tried coiling the rba bases for my two white subtank minis, one came with the kit, the second one I bought, both with V2 rba decks, both with the V2 airflow base and BOTH of them have shorting issues. I have made coil after coil after coil, using wire, twisted wire, twisted/ribbon wire, have snipped, wiggled and nearly chewed the ends off at the deck etc etc and nearly, well, all of them have been variable in use, they start at 0.6ohm, jump to 2.2, 2.8 even 9.9! Stop working, fizz, jump, sometimes settle then jump around again.
so last order I bought an extra airflow base as well as two extra rba bases, just in case.
so today, new wire.... 0.42mm Kanthal A1, recoiled the newly (this morning recoiled) rba deck, tested on the original airflow base, 1.2/2.2/fizz etc so out of interest fished out the spare air flow base and

whoop whoop 0.6 no jumping, fizzing sillyness 

i also have a V1 subtank bought from classies on here and no issues with that rba or airflow base so I'm concluding that the airflow based on the white subtank minis are a bit, well, suspect.

does anyone else have this problem? Is there anything I can do? Should I contact myepack? Or Kanger? Or just buy another silver airflow base?

I'm very sad about this   I like my all white tanks.

could this be due to the bottom 510 +ve pin not making a good positive contact with the rba/coil.
push it right in with no coil/rba fitted and fit one, it should push the pin back out so its slightly proud, try swapping the pin from your V1 subtank?


do occ coil heads work OK??

edit **  i have a couple of fasttech subtank mini base clones, they work a treat with OCC coil heads,
pm me if u want a loaner to test..

Thank you phatfil I'm sure you're right and it's something to do with the pin on the base. I've moved it about, removed and replaced it etc but it's not helped, not tried a different pin yet, the other bases are in use. It does the same with occ heads too. The original one I got with the kit is worse than the second white tank base I got, but still not as good as the replacement air flow base. Thanks for the offer of a loan, but I think I will head to fasttech, see if they have any white sub tank mini air flow bases and buy a couple, can manage with what I've got till then. I'm slightly relieved really, thought I simply couldn't recoil the rba bases and it put me off recoiling the occ heads. But I've just redone 8! Occ heads, all to 0.7 ohms, all tested on the v1 air flow base, so I now have a few spares, a bit more confidence and I no longer want a pack of rolling tobacco and some papers! (Was looking likely at 2.30 this afternoon )

Probably a stupid question, but what's an "airflow base" please?

[sleedale]

The part the coil screws into, joining the tank to the base, one with air holes in it.

And no, never a stupid question, there is no such thing here

Lol thanks - thought it might have been a special base with extra airflow that I hadn't heard of.

Heck, don't let them bring out anything else that can go wrong

So, some progress. The problem air flow base is the one that came with the subox kit tank. The new white subtank mini airflow works ok. I have tried swapping pins etc etc but it still cause the ohms to jump around, so presently is a white tank with silver base.
Decided to try contacting KangerTech and got a nice reply from a rep asking for a photo of the authenticity sticker on the box, and who I bought it from, suggesting that they would arrange a replacement. So I've sent the photo and details, but pointed out that I hadn't contacted the vendor (myepack) about this as it really isn't their fault.
So, now I wait and see if anything happens, I will let you know.
Not too bothered really, all three sub tanks are working with rba decks and I've finally got the right size wire to make coiling it simpler. Still the occasional leak, but that'll be down to my wicks I think.
As for the tanks, I love them, and the subox too (which I dropped while out with the dogs and managed to put a couple of small scratches on it but nothing broke )
Love being able to change batteries on this mod, makes life simpler for me at least.
