So let me tell you about this little single coil RM3 Rob built.

[sbmqcy]

I'll just chuck in my 2 cents. The rm4 produces much cooler, airier feeling vapor. The flavor is still very good, even set wide open. The rm3 dual vapes like a stock rm2. Tight draw, good for mouth to lung hitters.

I like the dense vapor from smaller atties, but I prefer lung hits. So I'm going to drill out my rm3s holes to 1/16 each and see how that compares.

For reference, my rm4 has dual 9 wrap (or maybe 10) 28 ga nichrome 60 1/16 microcoils. The rm3 had dual 9 wraps around a blunt tip needle (forgot the gauge, but closer to 5/64 or even 3/32) with the same wire.

Tonight I'm gonna play with seeing if I can get 26ga nichrome wires through the post holes on either of these bad boys.

Anyone have the single coil RM3? If so, how many posts does it have? Two or three? Thanks!!

Single coil with three posts here olefolks.

Thanks to everybody who responded. I'm thinking maybe an RM3 would be better for me. I sure don't need lung hits (that would finish me off) but I'd like to get some snap, crackle, pop! Is there a build on the RM2 or RM3 that might get that noise?

 

[olefolks]

Thanks Guys!! I googled the A6 and saw one that had two posts.

Where is the juice hole located on the RM3? Is it between the posts or pointing out?

I'm using a 9 wrap 27g K around a 1/16 drill bit and I get the crackling with it. Air hole is drilled to 1/16 as well. Btw this is on a RM2.

I don't have any 27g but I've got 28g, so how many 1/16 wraps would I need? Thanks

Twisted wire will definitely snap, crackle and pop.

8 wraps of twisted 28G around a 1/16 should be around 0.5 ohms. I would do it on a 3/32 bit imo.

I would go with 8 wraps of 28g in a 1/16 bit. That'll get around 0.9-1 ohms.

 

[thewomenfolk]

That chart is very good! But...it won't tell you what crackles in the atty. I want the same noise I get from my Sofia in the D-base tank, vapes very powerfully in my Provari. Can you do NR-R-NR wire in the Reo?

That's what I did, but I might have done 7 wraps. But no crackle at 1.02 ohms.

I've read the crackles are a by product of your build, your juice and I wonder if how much you squonk plays a role too. I've noticed I get the crackles with some builds and not others. I didn't keep track of what builds/juices created the crackle in my RM2. My Grand is a VV so my voltage settings prolly play a part too.

I think the crackle has more to do with the coil build because I get crackles with all my builds with the Sofia in tanks. Well, I am using it in a VV Mod, so I'm sure that makes a difference too.

The version of the A6 Rob uses has 3 posts. The single or dual coil setup just depends on either 1 hole in the top cap or 2. There are not 2 different deck configurations on the RM3s.

I've used both versions of A6 not supplied by Rob and I can tell you one reason he does it that way. The 3 post version of the A6 seems to be much higher quality than the 2 post versions that I've used. I've had 2 of them and both of them ended up with issues. The 3 post versions just seem to be built better. The only thing I can figure is that they are made by 2 different companies. It's hard to tell because neither of the A6s I've purchased have the manufacture's name on them.

When it comes to deciding between the single or dual RM3 it's just going to depend if you are a mouth to lung vaper that likes single coils or wants to up the heat and vapor with a dual coil setup. If you are a direct to lung vaper then go with the RM4 or RM5. Mouth to lung hitters are going to have a hard time getting a good vape with the larger chamber and air holes of the 4 or 5. Mouth to lung'ers are better off with the RM2 or RM3.

At least that has been my experience and my opinion.

That's what I did, but I might have done 7 wraps. But no crackle at 1.02 ohms.

If you're set on crackles, you're looking at more like 6 wraps (shooting for .7 ohms-ish). Now, that puts you into the subohm space, which is fine as long as you are comfortable/knowledgeable about that, and have the gold spring and firing lever (which come stock on newer reos) and a good battery that can output 20A or more.

If you have the older (silver/grey) spring and lever, you want to dab some noalox on them to help with oxidation (due to the lower ohms). If you don't have a good battery (e.g., AW 18650 1600 MaH is a popular one that would be suitable), I wouldn't recommend trying this. Not trying to put you off, but, you know, safety first and all that. Lots of threads in this subforum about subohming with a reo if this is concerning or confusing to you.

If you really, really, really need to have the crackles, the RM3 or 4 both get you there with dual coils (again, this involves subohming and the above considerations still apply).

^^ +1 for this.
