Vapefly Galaxies MTL RDTA | Squonkable and User-Friendly

Vapefly Galaxies Squonk RDTA review

The Vapefly Galaxies RDTA is a feature rich MTL rebuildable with top-notch performance. It has an easy to use build deck, a leak-resistant design, various airflow options, and the 2 mL tank can be filled via squonking or from a spring-loaded fill port.

This RDTA is the third in the Galaxies series, following on the heels of an RTA and the original Galaxies RDA. Here’s a closer look at this quality atomizer and how it performs.

Build quality and design

For RDTAs, the Galaxies is small. It’s only 22 mm in diameter and about 29 mm tall. I have RDAs this size!

It comes with two 510 tips with different heights and internal diameters. It’s got a small 2 mL tank section, a conical top cap, heat-sink fins, and various adjustable airflow options ranging from a super tight MTL to a restricted lung hit.

The Galaxies RDTA only holds 2 mL, but its capacity is increased by your squonk bottle’s capacity. If you don’t have a squonk mod, you can fill the tank from a spring-loaded fill port. The coolest part for me about the spring-loaded fill port is that it makes the deck leak-resistant – the fill port “valve” closes once you remove your bottle. In general, I think this is a great design for an RDTA. Vapefly isn’t the first to include some of these features, but I’m pretty sure they’re the first to include them all in a single-coil MTL RDTA.

Build deck and wicking

The dual post deck looks a lot like the Galaxies RDA deck, but with a slight modification. Unlike the original, both posts are gold-plated with curved bottoms in the post holes. This makes trapping thin wire easy, even if it gets pushed over by the bottom of the screw. This makes trapping thin wire easy, even if it gets pushed over by the bottom of the screw. It’s a welcomed upgrade from the RDA where the stainless-steel negative post has a flat bottom.

Because the wicking channels are 3 mm holes in the deck, the wick can’t be too narrow or too wide, which means that your coil’s ID must follow the same rules. It’s best to use a coil with an ID of around 2.5 mm to have appropriate diameter wicks.

To wick it, I find it easiest to cut your wick tails against the outside of the tank. Then use a pointer tool or your tweezers to gently push down the cotton, making sure it’s not bunched up. With this approach, I’ve had no problems at all with my wicks staying wet. And since the tank is a low capacity, I never have to consciously tip the tank to wet the wicks – it just happens.


Vapefly “gets” MTL vaping! They nailed it with the 2017 Nicolas tank, and then this year with the Galaxies RTA and RDA. It only makes sense that this RDTA would do MTL vaping equally well.

As noted, there are plenty of options for airflow. The deck has bottom-fed airflow or bottom- and side-fed airflow. To add the side airflow, just unscrew the grubs on the back side of the posts (but don’t remove them or the flavor will suffer). Using the side airflow will increase the amount of air, making it more of a restricted lung hit than an MTL.

There are nine holes on the top cap; three on one side and six on the other. You can either double your airhole selection or use it with a single hole. The three airhole sizes are about 0.8 mm, 1.4 mm, and 2 mm. Being a fan of a tight MTL, I enjoy using the 0.8 mm single hole with just the bottom-fed airflow.

The Galaxies RDTA comes with two 510 drip tips which are basically extra airflow options: a short 11.5 mm translucent tip and a 15 mm elongated black delrin tip. The black tip has a base opening about 3.5 mm in diameter that tapers off to 2.5 mm at the top, making it perfect for a strict MTL. The shorter tip, which is the same tip from the Galaxies RDA, has a 5.5 mm base opening that tapers to 3.5 mm at the top. It can be used for MTL all the way to a restricted lung hit. I like both tips, but I prefer the shorter tip due to its ergonomic contour – and I think the flavor is better with it.


Simply put, the Galaxies RDTA just works! And this is coming from someone that typically doesn’t like RDTAs much at all. This atomizer changed my perception of how an RDTA can perform.

I’ve been using the included 1.0-ohm Ni80 pre-built coils that come with the tank (mine metered out to 0.82 ohms).

The draw is perfectly smooth and quiet, and the flavor is above average for an MTL. Although I’ve always preferred an MTL draw, I typically don’t view MTL as being all that great for flavor. I like MTL vaping for the throat hit and the cigarette-like draw. But with the Galaxies RDTA, I get the tight draw and above average flavor. I’ve been pleasantly surprised at how good the flavor is from this tank. If you’re a fan of nic salts, this tank will do your juice justice! Also noteworthy, I’ve had no leaking, gurgling, flooding, or dry hits (which has more to do with my build, but it’s still worth mentioning.)

Although I use the tank with a squonk mod, I also like to change things up. Sometimes I fill the tank from the spring-loaded fill port with a different juice than the one in the squonk bottle. That allows me to travel with two juices on board. And sometimes when sampling juices, I just drip directly onto the coils like a dripper. It’s nice to have that kind of freedom!

  • Designed and manufactured well
  • Easy to build on
  • Two convenient refill options
  • Great flavor for MTL
  • Really nice draw for MTL or a restricted lung hit
  • Leak resistant
  • Silent draw (no whistling)
  • Wicks well
  • Quality O-rings keep the top cap firmly on
  • Two 510 drip tip options
  • Not much leeway in coil ID
  • The overall aesthetics are just okay

I strongly recommend the Galaxies RDTA for fans of rebuilding and MTL vaping. Aside from not having much flexibility in the internal diameter of the coil you can use, I can’t find any other objective cons with it.

If you’re curious how this performs versus the Galaxies RDA and RTA, I think the RTA may have the best MTL draw of the three, but the RDTA has more options and slightly edges the others in the flavor department. The RDA was good when it came out, considering it was one of the first mass-produced squonkable MTL RDAs this year, but the Galaxies RDTA fixes all its issues and comes in an even more complete package.

What do you think? Have you tried any of the atomizers of the Galaxies series? Let me know in the comment section.
