Need help with my RSST!!!

Recently got one and started playing around with rba's. My coils came out pretty good IMO and all are glowing evenly. Read out at 1.0 ohms, one at 1.2 ohms using 28g Kanthal with a 4/3 wrap on 500 mesh.

Im using 12mg Juicy Fruit juice, which is my ADV on my carto-tank/clearo's. On the RSST, this thing hits like a truck, to the point where I can only take one vape from it if that, then I have to put it down and drink a gallon of water.

Do I just need to lower the Nic content? Drill out the air hole?

Also, I dont seem to be getting as much vapor as in some of the videos i've seen, or even compared to my carto-tank. What gives? No hot spots that I can see, contact is pretty good from wire-wick as its not too tight or too loose.

Also, Im using my RSST on a Smoktech Telescoping mod with an Efest 18650 Battery.

I LOVE the flavor on this thing, as well as how it looks, and I want to use it so much more, but the major kick to the back of my throat makes it unvapeable. HELP!

The PG/VG Ratio of the juice is unknown to me as its from my local B&M who states that their liquids contain less PG. The juice is thicker than most of the 80/20 that I've purchased elsewhere.

A 4/3 wrap of 28g Kanthal on a 1/8" wick should be netting you about .7Ω, I believe (or less). Perhaps the RSST doesn't conduct so well. In any case, vaping at 1Ω is some profound stuff. If you are used to cartos and clearos, that's probably what's kicking your ayss. Lack of steam can be caused by a lot of things. Air hole size and alignment is the first. A good, average air hole size is 1.2mm or 3/64". Some juices don't create as much steam as others. If you have only 3 wraps facing the air hole, you might not be drawing air across enough wire. Video steam is "well lighted". So, those are some possible factors.

edit: oh, yeah, and strong throat hit is also a sign of inadequate air flow to your coil. Make sure air hole is right in front of wick/coil

im no expert but heres my guess ...take out fill plug?? make sure you wick isnt touching bottom of tank, although on the rsst it dont matter as far as shorts go but maybe it might help wicking also- just a guess- and yea i found i had to lower nic content with the gennies, try 8mg- cause these so much vape.. maybe diff vg-pg ratio? with 1ohm on your mech you should be getting heaps of vape!!! also those dudes on the vids are vapeing sub ohm coils not my cup of tea.. .. pdib seems on to it!! think that advise would be right!! good luck!!

I haven't tried the RSST, but alot of these atty caps; you can enlarge the air hole a bit/enough by reaming with an awl, corkscrew, whatever. If the draw doesn't feel tight to you, enlarge as a last resort. You might not like a looser draw.

and, yeah, like mad maori said, lots of folks lower nic content for the Genny

The draw is kinda tight, will definitely be opening that up with a drill bit. First i had tried 18mg 80/20 juice and that was very strong, but still low amount of vapor.

Then switched to this 12mg which has more VG, but same strong throat hit.

I think I have figured out why im not getting as much vapor, though not sure how to resolve it yet. Although my coils glow evenly, they are not as bright as they appear to be in some of the videos/images i've seen here and online. I've been sitting at my desk for the past half hour trying to get them to glow as bright as it does when i fire it for the first time using the pulse method, but as the rest of the coils light up the glow gets a bit dimmer. Got to figure out how to keep it even, but burning as bright as it should.....

fresh battery?

Started with battery at 3.9v, following the recommendation from PBusardo's video of not using a fully charged battery.

Battery is dead now from trying all night, going to get some sleep as I have a long day tomorrow.
I will continue trying to figure this thing out, thanks for trying to help pdib i do appreciate it.

i know EXACTLY what you are talking about. i was using the 3/4 28g and it was unbearable on my throat. i've adjusted my build and now i get lots of flavor and vapor...and have a vape that's less "harsh" on me:

1. drill out that airhole to 1/16.
2. wrap teflon tape around the center pin before assembling (one of the things that was giving me a harsh hit was juice build up on the 510 connection).
3. 500 mesh
4. 3/4 30awg @ 1.4ohms.
5. evenly space coils. i wrap outside to outside, no "s" coil. it's the easiest to do and produces the best results in my case.

D3mon what mg juice do you use? I'm going to try to get the air hole drilled out after work today. I've got some 30awg kanthal, will give that a shot.
I only tried the "S" coil once but that didn't work out as well. I'll stick to the outside wrap, and yes the air hole has been lined up right in front of my wick/coil.

I'll try this after work today and check back in.

i don't know if yall are having trouble with drilling that hole...but it's as simple as a cordless drill, a 1/16 bit, and 12 seconds :D

Yeah, that shouldnt be a problem. Just that I have my tools in a garage thats not close to where i actually live. Weird I know but...ill have to just go over there and drill it out, then back home to try again.

I second the larger air hole... I had the exact same issue with my RSST at first (weak but intensely flavored vapor and wicked TH) and found that drilling the hole to 1/16" make a huge difference in both the amount of vapor and a smoother, more mellow flavor/TH.

I'm running a 3/2 wrap of 28awg @ 0.7ohms, 18mg 50/50 PG/VG juice.

I have 3 RSSTs. All are drilled out to 1.2mm. Perfect for me.

NOTE! there is a BIG difference btwn 1/16" (1.5mm) and 3/64 (1.2mm). some folks would say that 1/16 gives no resistance to your draw (like breathing with your mouth open). Lots of folks are liking it. If you can do it in steps, DO SO!

Personally, I'm with Rule62 on this one. AKA #56 drill bit
