Everyone is working together these days! One of the latest collaborations is the Vapefly Core RTA, a 25 mm rebuildable tank for clouds and flavor.
The Core RTA is a new project from Vapefly plus DampfWolke and The German 103 Team. DampfWolke is an established German YouTube reviewer who assembled The German 103 Team of that same number of passionate vapers (mostly from Germany). With that many minds coming together to create an RTA, it’s hard not to be interested. Here’s a closer look at this new RTA and how it performs.
Colors: stainless steel, gold, black, rainbow
Price: $28.99 (at MyVpro)
Overall, the Core is built and designed nicely with only a couple minor issues. It’s a 25 mm tank standing a bit over 46 mm with a translucent removable PMMA drip tip that fits most Goon-style tips. It also comes with a 2 mL tank section along with a 4 mL bubble glass.
The Core RTA’s threads are smooth, and the 510-pin sticks out over 1 mm. I’ve had no mishaps or shearing with the silicon O-rings, but the adjustable airflow ring is much too loose.
Aside from the unique semi-circle airflow that hits the coils from beneath and behind, the Core RTA is fairly straightforward. It’s got a low-lying GTA-style deck with clamp posts for dual coil builds and it’s apparently going to come with a chamber reducer to make it a single coil deck (mine did not). The top fill is a simple screw-top, but the fill ports aren’t very wide. It’s best to fill this tank with a unicorn bottle. And although the top cap has indentations, it’s hard to grip due to that carousel canopy-like shape. The easiest way for me is to apply downward pressure and then unscrew.
Such a beautiful deck! It’s a clamp-style dual post design with gold-plated flat head screws, similar to Vapefly’s Wormhole RDA. The clamps are attached to the bottom of the screws, so they trap and release leads easily. The best tip for installing coils is to cut your leads ahead of time because both coils’ leads will share terminals (if using in dual-coil mode). But there’s a lot of space in those post holes.
Once you straighten out your coil, it’ll basically be in the ideal spot. There’s very little hassle with getting your coil placed just right.
Wicking is also easy. Two wick tails share one port on each side of the deck. You have to tuck your wicks down and forward to fill the ports, which are directly under the outside post holes. I’ve gotten on best with tails about 11 mm. My wicks barely end up touching the bottom of the tank so there’s a little room for juice flow.
With the airflow wide open, the Core RTA is smooth and relatively quiet, though not totally unrestricted — you can breathe through it, but you’ll feel a slight resistance. The internal air holes are laid out in a semi-circle they’re calling a “Q” airflow system. To each coil, there are 11 small airholes: 8 holes underneath the coils (laid out in two rows of four holes), and three holes at the center-post, stacked in a triangular layout. By chance I am also vaping on the single coil Kylin Mini and the Core RTA somewhat reminds me of that airflow design except the airflow of the Core RTA hits the bottom and back of the coils, instead of just the bottom half.
I’ve enjoyed using mine with the airflow closed off about ¼ of the way. The only real issue with the airflow system is that the adjustment ring is too loose. It’s not like it spins freely, but I can easily turn it with the tip of my finger and hardly any force. Also, when adjusting the airflow to a lower setting, I get a little turbulence when taking a long drag — but I don’t mind it so much because the Core RTA is not very loud in any setting.
The Core RTA is a cloud maker with good flavor. I’ve tried several builds, slight modifications to coil placements, and varying wicking approaches.
The best flavor for me came from having the coils raised about 1.5 mm from the bottom airflow holes while being closer to the center-post air holes. My natural instinct when dealing with bottom-fed airflow is to get the coil as close as possible to the holes, but this one worked out better with a smidgen more space.
In none of the builds have I had an issue with leaking, gurgling, or spitting.
Vapefly is marketing this RTA as having “no heat,” and I can vouch for the body of the atomizer staying at low temperatures regardless of the build I used on it. On the other hand, the vape I got from it was not cool, which is a good thing. It’s comfortably warm even with aliens at 80+ watts – my favorite build so far. Fortunately, it has a 4 mL bubble glass so I was able to get a little extra time before a refill.
If you have to deal with TPD, the 2 mL tank will have to get filled quite often – there’s just no way around it for how this tank performs. Expect to use a good deal of power to see it perform at its best, which will also mean going through some juice!
The Vapefly Core RTA is a nicely designed RTA that performs well. Aside from the top cap being a little hard to grip and the airflow ring being too loose, there’s nothing really to quibble about. I enjoy using it and would recommend it to someone looking for an easy-to-build cloud RTA capable of good flavor.
