Thanks Paul. Why did Kanger change the holes of the rba to a smaller size? I haven't used one yet but am thinking it will affect wicking.
I have one of those and don't use it. Maybe it works better with thinner liquid or helps with slowing down the flow of liquid with the loss of vacuum when filling a top tank version.
So finally made it back to Az. and after traveling through Nevada and northern Cal did not have even the slightest leaks. Up and down the Sierra moutains and even up to lake Tahoe not one drip out of four of them, various factory and rba coils. Then on the way home after 2 weeks of flawless performance one of the factory 1.2 ohmers flooded profusely out of air hole. Granted we were coming down mountains out of San Diego into the Imperial valley. So I am pretty satisfied with these STM tanks, although not bullet proof they are the best I have used so far. Just thought I would give a report, by the way I was running 50/50 diy juice.
Looks like they started packing the STM with the same RBA that they switched to with the Toptank. Don't like the smaller, higher hole since it forces you to refill much earlier, but I think they made the switch to avoid leaks when top filling. I used the original V2 RBA with the Toptank and it leaked profusely after top filling. Stopped when I switched to the chimney that came with the Toptank.
On another note, I found the replacement post screws for the RBA on Fasttech:

I tried them out and they fit nicely. But I can't find replacement screws for the side to keep the chimney on. Someone (@LeoBak maybe?) posted that the threading/size of the side screw is M1.4 x 0.3 pitch x 2mm, but Fasttech doesn't carry that size. I've gone to two hardware stores - nothing. Anybody got any other ideas?

Same to report here. Although they seem to leak like all the other tanks when taken up and down mountains. Yesterday we went to the top of our local Mt Lemmon, 7000 ft. and one of mine started to leak at the top. Oh well I guess its just the nature of the beast when your dealing with internal pressures and what not. Stay cool, waitin on the rain, maybe next week?
Anybody know where to get that oring that sits at the bottom on the outside of the subtank mini coil? Kind of a clear white milky ish color and very squissy (pliable)
They look like common mini drip tip o-rings cv. Nominally 1x8mm (id/od) is what I see lookin' at the KT RDA, OCC. Look around at LV and these (flats) may work...

Also Desert Vapes always had quite an assortment…

They do get stretched with age and tend to fall off. When they do the vape goes in the dumper fast as one tends to forget about the little part.
I often find them doing runaway cartwheels around the house. Keep a lookout!
Good luck.
Thanks Mac

Thanks but............I can't order "just" o-rings from fasttech. I know, free shipping and all, but it just wouldn't seem right. That means I have to find something (or several somethings) I want, need, gotta have and/or can't live without.
I only "thought" I was done shopping for a while.
Let us know if they work.Thanks Mac

Thanks!
Need some help. In building the STM last night I kept getting crazy readings. No matter the gauge (tried 26 and 29) and each time the build would jump radically from like 1.1 to .40 and back again. Any advice?
I'm no expert, but the only time that's happened to me is if the coil isn't cut short enough and grazing the chimney on the side.
Another thing to check, the positive post sometimes becomes loose, if so, stick a small screwdriver through the air holes at the bottom of the RBA, carefully tighten. 
I am confused about where you are saying to tighten up? Air hole at the bottom of the rba? I do not see an air whole at the bottom of the rba.Another thing to check, the positive post sometimes becomes loose, if so, stick a small screwdriver through the air holes at the bottom of the RBA, carefully tighten.
