Kangertech Subtank RBA problem

[Nconway2709]

I have a kangertech subtank kit with a rba. I have 26 gauge kanthal and some cotton from the local vape shop.I've rebuilt this atomizer numerous times and it always seems to taste burnt. Anyone have any advice? The kanthal is wrapped around a 2.4mm screwdriver about 5 or 6 times and is burning at 3.1 volts, 17-20 watts and 0.6 ohms. The cotton is neither too loose nor too tight. I did prime it by putting some juice onto it before hitting it. I've read about hot spots but have no idea what that is. Does anyone have any suggestions on how to make a good build off of this. If it matters my juice is a max VG and a brand called "Jüs". Any advice is appreciated.

Well, the first culprit is the "some cotton"! High quality Japanese organic cotton, Ko Gen Do, or my fave, cotton bacon shouldn't give you any burnt flavor.

I would suggest trying a bigger coil. I use 3mm coils in my subtanks. They will hold more juice. Make sure juice channels are not blocked.

Do you have the old version or the new one? The new version of the rba has holes drilled in the chimney, which definitely improved vg wicking. If you don't have the new one you should either drill some holes or buy the new version with the holes.

I'm experiencing the same issues with my subtank. Rda is giving me the same burnt taste.... Gave up on the rda. Solving my issue by not really dealing with it and ordered a zephyrus tank!

Never had a burnt taste on old or new rda decks, are you priming it thoroughly first?

I find that contact coils don't keep up with wicking the juice as it burns it, the spaced out coils seem to work better in them.

My Subtank rba build is .8 ohm, 26g Kanthal, 6 wrap microcoil at 2.5mm. Perfect.

But I should add that's at 14 watts, so my Provari battery lasts the work day!

I only use micro coils in everything I build. I find the flavor and vapor density to be better. And they're easier to work with.

Just starting to get into builds so don't know to much about it yet, once I get ,y zephyrus I'm excited to learn everything I need to know. Ordered a sigeli 75w tc also

Vg is hard to wick, you can thin it with a couple of drops per tank of distilled water. Also make sure your wick is not cut too short. I believe Pbusardo has a Youtube video showing a build on the Subtank RBA. that may help you some as well as building your coil spaced out 5 or 6 wraps at 3mm.

I have the same issue, tried various coil diameters, resistances, liquid ratios and wicking, everything just tastes bad, but I haven't tried spaced coils so I'll try that. Do you get better airflow with spaced coils? That's what I really want, more air...

No offense to zephryus users but that thing leaks like a monster. Flavor wise i still aim for subtank. As to answer your question on burnt taste, its not the rba problem. Get some good cotton. How you cotton it is another. everything boils to technique. Can google up riptrippers subtank on youtube. All in all i dont follow entirely his method of cottoning. If you are firing 20+ watts and 0.5 ohm u are sure to get burnt taste if you drag it for more than 6-7secs for many times without letting the juice get soaked by the cotton. Sometimes its pure common sense. Try not to put cotton over the coil or near the post. It normally burns there as well. Thanks

sounds good

so my guess would be cotton too tight or maybe it's the older rba head with the narrow juice channels?
