First RBA, RSST. Have some questions

[skakid812]

Hello all, I will be getting my first RSST here soon and have some questions. I have watched tons of videos on rebuilding, and I am confident that I will be able to build a decent coil.

What I'm confused about, is the thickness of coil, the wraps, and the ohms it comes out to. Coming over from clearoland, I understand that a 1.8ohm clearo usually does pretty good at 3.7volts, or an average ego. So what I dont understand, is watching all of these videos and seeing .7, or .9 ohm coils doing very well at similar voltages. Is there a difference? I will be using my MVP2.0. Should I just keep it simple and use 32guage wire and test a couple wraps to see?

Also, with SS mesh, I am hearing that #400 or #500 would be best. I will be using bobas so it is quite thick. With this delivery system, is there a constant need of tilt and twirling to get the juice up the SS mesh, or does it provide a decent delivery on its own?

Thanks in advance.

As far as the 400 or 500 mesh, I never noticed a difference between them. For the resistance, you need to build something that is 1.2 ohms or more. I would probably recommend something like 1.8-2.2 ohms with the MVP. That way, you could still adjust the voltage/wattage pretty well.

The MVP will have an amp limit, so if you build a lower ohm coil, like 1.2 ohms, your MVP will only fire at lower voltages. I used to like 32 with my regulated mods. I never tried to build a micro coil with 32 though. I'd probably recommend 30 gauge with micro coils for the MVP though. You need to use a lot of wraps to get 1.2 ohms, let alone something with more.

I just built a 1.4 ohm micro coil on my RSST using 10 wraps of 28 gauge on a 1/16 drill bit. Its doing amazingly well on a mech mod. I think you would be fine with a 1.5ish ohm could on your mvp at around 4.2 to 4.5 volts. Fyi, I'm also using cotton in "auto-dripper" mode. I love this build. It seems to work extremely well. You might check it out.

Amp limit? I have been looking for more info on sub ohm stuff but havent found much. What are the basics of it? I dont understand how lower ohms would produce better vapor. I thought a 1.0ohm coil at say 3.2 volts would be just as good as a 2.0 ohm coil at 4.2 volts.

If you want to get the most out of your RSST get a mech.

I may be wrong, as I don't own an MVP, but I believe it will only fire a coil that is 1.2 ohms or higher. You wont be able to sub-ohm with this device. If you want to sub-ohm you will basically need a mech mod. However, check out microcoils, you don't need the sub-ohm to get an amazing vape.

ah see this is where I'm lost. I need to do more research. What exactly is a mech? Is this just a battery system that is set to a standard voltage, like an ego? I dont understand how sub ohm produces better results. And a microcoil is basically thin wire wrapped a bunch of times to form a nice neat long coil?

On mesh size and tilting:

I use #400 in an RSST with Bobas. 2" x 2", with straw hole in the center. I don't have to tilt until juice level gets within 1/8" of the bottom of the tank.

I also use it on a mechanical, from 1.0 to .8 ohm. Since there is no battery regulation in a mech, with a fresh battery (let's call it 4.15v) I'm getting 17 - 21 watts of power, and drawing a little over 4 to a little over 5 amps, which any good 18650 IMR battery will handle (I happen to use AW's). Just have to be careful not to draw the battery down but the vapor falls off rapidly after ~ 3.5 volts so it's usually not a problem. With my vaping style, that's about 5 - 6 hours of vape time off of one 18650 battery. Basically, sub-ohm gives more power to the coil with more vapor production, more throat hit, and a hotter vape. For me, that spells Boba's Bliss!

Go over to the microcoil thread for all you ever wanted to know about 'em.

Amp limit on the MVP is 3 amps. So on a 1.3 ohm coil (I read this may be the lowest resistance it will fire, not positive on that), you can only go up to 3.9 volts. At 1.5 ohms, 4.5 volts is the limit. It should error out if you go higher. The calculations are just Ohm's Law, V = I x R.

A mechanical mod just connects the battery straight to the atomizer with no wires, regulation, or circuit board (electronics) of any kind. I'm sure you can do a little reading and learn more about them.

Don't worry about microcoils for the RSST.

Subohm just gets the wattage higher, so more heat with thicker wire. This is the realm of mechs and only a few high-end regulated devices.

Just try to go for 1.5 ohm or higher for now and see how it goes. Good luck!

My 2 cents:

There's many different aspects in the world of rebuilding. And many views/preferences for each aspect. We're all chasing the perfect vape. But that "perfect" is different for each of us. I say, don't worry about mechs or micros, or even cotton...actually cotton may be easier. Go for a 1.5-1.8 on your MVP. After building even your first coil, you'll be surprised how much more you know. You'll know why people prefer warmer or cooler vapes and how voltage/airflow relates to that. Just dive in. On a regulated device like the MVP, there's little risk involved. Have fun...vape on
