Cobra RBA

[D4rk50ul]

So I have been messing with this thing quite a bit, fixed the air hole so it flowed properly and made a working 1.8ohm wick to use on my provari. I am wondering what the best setup is to run on this thing, U-Wick, Dual Wick Dual Doils, Or just a single coil and wick. It's pretty difficult to not get that top coil burn so I'm not really looking forward to another setup but if there is a better way to do things I'd love to know.

Also trying to figure out if I can get it to wick without air lock while leaving the fill screw in place. I'd like to have the ability to not have it upright constantly.

Any input is appreciated.

You're on the right track. The Cobra is a nice rba. I run mine about 1.8 ohms also, on either a Provari or Sig ZMax. I use either 400 or 500 mesh, 32awg kanthal A1. I leave the fill screw out on mine.

I just made a chisel tip wick a fraction smaller than the hole. Coiled it with 32 awg about 7 times, ending with a 2.5ohm running it at 4.8v. It wicks fine with fill screw installed, kind of made my day

It never hurts to at least try leaving the fill screw in. Some people find it works ok; some don't. I make my Cobra wicks about 3/32". Rolled fairly tight. No center hole. I leave the fill screw out. Air hole in the top cap is stock.

For the Provari, just keep on keeping on. You don't want to make a dual wick/dual coil kind of setup since your new to all of this. I always loved my Cobra, it was the best functioning genesis I've ever used and I miss it. I never did anything but a single wick and super low ohm coil on it, but since you're running it on a Provari you don't want a super low ohm coil, anywhere from 1.3-1.7ish is good for you.

If you have a provari v2....then I would definitely get some 30g wire and experiment with that. It is much easier to set up a 30g coil vs the 32g...also the builds are much more stable and last longer. Since you are already doing 7 wraps of coil you should have no problem with the 30g wire.

Try to always leave the fill screw in....since it will make your device very pocket friendly. I take my cobra everywhere with me and I always lay it on its side. It has never leaked a drop.

I love my Cobra 3mil... i was disheartened with it when i had my Provari and no mechanical that would handle low Ohms... it sat on the shelf...
I admire guys like Rule, who are good at making coils for VV or regulated mods... but sub 1.0 Ohms is where mine shines now, on a Polidiac: 28g 4/3 wrap, .9 or .8 Ohms... fill hole in, air hole at 1mm is no issue when vapor is bursting out to beat the band.
