Kanger subtank mini rta build question

[Thevapebro]

ok y'all I have a first gen subtank mini and I have yet to be able to get a build working without getting dry hits. I have a 2.4mm 26g coil in it around .45 ohms and I can't seem to get it working correctly I'm not sure if I'm wicking it wrong or what. I have been building for some time and I'm thinking that it might be that I have to mod it to be more like the second gen decks with the holes in the sleeve like the stock coils have. I've been using rebuilt stock coils but would like to get the rebuild deck to work so I can say I beat it haha I would appreciate any input on better ways to go about this

I mod the V1 RBA by enlarging the notches on the base.
Works better using 25/75vg.
Also try a 3mm coil for more wicking.

When I got my 1st Subtank Mini, I took One Look at the v1 RBA Section e-Liquid slots and went... "Nope. It aint gunna works As-Is".

So I got out a Flat Needle File and made the e-Liquid Slots about 50% Wider. And about 50% Deeper.

Precision Needle File Set 12 Pc

Then did a 3mm 28ga NiChrome 80 1.0 Ohm build on it using "Pancake" wick. Filled the tank with some 20PG|80VG DIY e-Liquid and away I went.

Hits Great. No Leaking. No Dry Hits in the 15 ~ 25 Watt zone for that Build.

Unless you are using a VERY Thin e-Liquid like a High PG, I can't imagine an Un-Modded STM v1 RBA section working well unless you are using a Very Low Wattage.

The e-Liquid Slots are Just Too Small IMO.

I used a dremel on mine and no dry hits anymore and I use 50/50 with never any leaks unless hill climbing in the rv.I have been running the coil that came installed in the rta heads, they are .5 ohms and I have been using these same coils for 8 months without changeing them. These things simply work after the channels are widened like Zoidman and Puffon recommend.

I received 3 STM Styled RBAs from FT today. None of them are registering on the ohm meter. Any advice other than not buying these again in the future?

What type of Builds did you put in them?

It's the build that came pre-installed. The .5 coil

It just won't register

 

[zoiDman]

It just won't register

Is the Coil or the Snipped off Coil Leg touching the RBA Barrel?

Try taking the RBA Barrel Off and see if they Register.

Good idea. I'm going to do that now

Unfortunately, that didn't work either. Should my next step be pulling out the pre-installed coil and building another?

Just don't do this! These came with my STM that I traded an Aspire Quadflex for. Dude got a tad bit carried away with his Dremel IMO!!!

I would leave the Coil in it for the time being.

Try Unscrewing the RBA Section from the Base. Then take a straighten out paperclip and poke it thru the Hole on the Base End of the RBA Section. Now turn it to make sure it is tight.

Then put the RBA Section back in the Base and see if it Registers.

BTW - When the RBA Section is screwed into the Base. How far is the 510 Pin sticking out of the 510 Threads in the base?

Hopefully these pictures will answer your question?

Try pressing the base 510 on a table, while tightening the RBA.
You should feel if the RBA is contacting the pin.
(the screws rusted on my clone RBAs)

For the paper clip trick, do you mean to do it like this?

 

[zoiDman]

Hopefully these pictures will answer your question?

Yeah... That's what Mine look like.

Have you tried putting it on a Mod and seeing if it Registers?

 

[puffon]

also try the base/RBA on a mod.
It may just be the ohm meter not making contact

 

[ChelsB]

Yeah... That's what Mine look like.

Weird, it IS registering on the mod! Problem solved, I guess. But why didn't it register on the ohm meter? I checked the meter with other coils and it's fine

 

[zoiDman]

Un uh.

Put the Paperclip thru these holes...

Then make sure then end with the holes is tight.

The Thing with the holes in the Above picture holds the Post to the Deck.
