I am still a newbie and would love some help.

I currently use a mechanical mod with a rda.

I'm very excited, I'm getting a Russian 91% in a few hours of the mail delivery is going smoothly.

In case it matters, I use a Nemesis and a 18650 and a 3.7 volt battery.

I like flavor. I am a flavor chaser. And I don't know what to build my Russian at. I currently have a .6 ohm coil. Should I just go with that? Is there a difference in the way a rda and a RTA vapes at the same ohms?

If you use a mechanical mod with no variable voltage and have a RTA, what are your ohms you use? (And if you use 26 gage wire, how many wraps to get there and on what size drill bit)

Thank you in advance!

it really depends on the rta you use. personally for me on a kayfun the lowest I used to make my coils at were 1.2 ohm and up. That was what worked for me. the russian is practically the same. Its designed for flavor and not clouds. Experiment and maybe people have a build for lower ohms on your russian. at the moment I have been using a sting ray x and the erlkonigin and also now an orchid v4. the erlk make 0.8 coil and get at least to 25 watts n7ce vape. the orchid much higher. I think start off buyjng some 28 gauge and make your ohm at least 1 ohm to start and see from there

For a mech, my preference is for 0.8Ω - 1.0Ω using 26ga, 2.2-2.4mm Coil ID when building for my Kayfuns.

EDIT: 8 wraps at 2.2mm will get you about 0.9Ω. FWIW, 2.2mm is the diameter of a coat hanger, which as it turns out, is great for wrapping coils on.

Thank you! Appreciate it. I will try that when it comes in. Waiting sucks. I have the Russian and six more e-liquids coming in today.

So that is with a variable voltage device?

IMO, Russian / kayfuns perform best 1.2 or above, when I used one my favorite was 1.6 ~ 1.9.

Using a VV/VW device I'd suggest the same ohm range then use the variable power feature to tune / adjust the vape to your liking.
Using a mech you have to experiment / wrap then wick various ohm ranges of coils to tune / adjust the vape to your liking.

Always check / verify resistance of the coil with an ohm meter / dvom before firing the coil on a mechanical, most if not all VV / VW devices with built in ohms meters have protection circuitry that won't fire too low of ohm builds or shorts.

You have to compare apples to apples. When you were building 1.6-1.9Ω for a Kayfun, I doubt you were using 26ga wire on a mech like the OP wants to use.

All my KFL+ builds are 1.4ohms and up due to airflow and wicking constraints.

Here are a few links for you regarding building coils and getting the resistance just where you want it:
1. Steam Engine
2. Coil Toy Calculator

Make sure to check your build with an ohm reader or DMM before putting it on your mod and firing it.

With my Kayfun clone on a mechanical mod I set up at 0.85 ohms using 27 gauge Kanthal on a 3mm, or 1/8" drill bit. This is it in the Steam Engine calculator. This is it with one more wrap at 1.2 ohms with the 27 gauge wire. I found it to be a little slow to fire and just not as good for me. If I wanted to vape it at 1 - 1.2 ohms I would try it with thinner wire and see how that went.

But again, this is just me and my preferences. A lot of people like the Kayfun type attys at 1.5 - 1.8 ohms with thinner wire. It all depends on your preferences.

Russian 91%'s are much like Kayfun Lites, the decks are almost identical. Downside, Kayfuns you can generally get away with in the 0.6 to 0.8 ohm range, a Russian on the other hand, around 0.7 ohm you run the risk of melting down either the center pin insulator, the positive block insulator or both, so it is highly suggested on a Nemisis, build it in the range of 1.2 to 1.4ohm with 28g possibly. Still gives a decent vape, and, it is a good vape through most of the battery drain until about 3.5 to 3.7ish volts on your charge.

I run a Kayfun Lite Plus V2 on a mech at 1.3R - 28ga kanthal 6/5 wrap on a 3/32" bit. Its my ADV.

    I know it's just me ... BUT ... I wouldn't use 26ga in a KF/Russian. It's just to many wraps to get the resistance. (slow to ramp up)
    I used 30ga (1.25 ohms) wrapped micro style around a 1.5mm Ekowoll wick. It's been rinsed & dry burned a few times, but that coil has been in daily use (but not all day) on a Nemesis with a Kick-2 set at 9 watts for close to 9 months.

    HELP AGAIN!

    I built several coils for the Russian. Practicing. Finally got one at .5 ohms (the rest were above 1.5, I'm a newbie, sorry). So I said screw it, I normally vape at .5 ohms. I'll do this.

    So I put it on, make sure it isn't touching the deck. And...it sucks .... Warm vape. ZERO flavor on something my zenith is giving me plenty of flavor on. So it isn't the juice.

    And barely anything it coming out. And I have the adjustable airflow all the way open.
    And it tastes horrible. Burnt almost. ...? I'm so devastated. I was so excited. It isn't working at all.

    And for the first time in almost a mobth, I am so frustrated and ...... I want a cigarette bad.

    Simple solution:
    Your Russian is not one of your RDAs, and doesn't work the same as your RDAs. The Russian has a smaller vapor chamber than your RDAs. So don't expect the same resistance to work the same.

    Your Russian will produce a very nice vape, but it's up to you to find the build that delivers what you want.

    My simple trick that I use when sorting a new device is to always have a favorite vape sitting at my elbow while I do it. You wouldn't believe how many times that has kept a new kind of atty from ending up outside in a snow bank!

    and I still like Wheelie's avatar :D

    Sounds like a couple of things happening here. 0.5 is a bit low, IMHO, for a Kayfun (even on a mech). And I'm going to agree with the crowd saying you want to build lower for a mech than you would for a vv/vw mod. That said, ~.8 or .7 should be good. I run a Kayfun on my Slug at .7 and have had no problems. For me it hits the same as running a Kayfun at 1.2, @ 15 watts on a vv/vw device.

    On to the burned taste.... To me this sounds like a wicking issue. How much cotton are you using? Are you making sure to wick your cotton to the deck, not into the channel, and not over the deck into the threads? Are you making sure you can slide the cotton cleanly through the coil (back and forth) without damaging it (while not having empty space)?

    This is just my opinion (and I may get blasted for this, but I've tried just about everything and this is what I've noticed), but the Russian is less forgiving, in terms of wicking properly, than the original Kayfun or the EHPro clone. The most forgiving Kayfun style RBA (and my go-to recommendation to those new to RBAs) is the Lemo.

    30 watts in a Kayfun/Russian isn't typically going to end well, unfortunately. It'll be warm, and most likely, burnt.

    Did you try any of the 1.5ohm coils you'd made? You might be surprised.

    I had a terrible time getting my Kayfun working on a VV. Deepening the juice channels helped a lot, no more burnt hits. I hated building a coil and filling it up, only to find that it was time to drain and see what the problem was. It can be a pain, but you'll get it!
