Hi Vaping Underground members, In this review i take a look at the Mulan MTL RDTA from Cthulhu Mod. The Cthulhu Mulan MTL RDTA was supplied for the purpose of this review by Ella from Sourcemore.

Introduction
Since Cthulhu Mod came on the scene they have continuously released MTL atty's even when the MTL scene was quiet so now the releasing of MTL products has picked back up (which at long last as been the case in 2019) Cthulhu show no signs of slowing down.
The Mulan MTL RDTA (i would prefer it being called a top coiler RTA as really RDTA's don't seem to exist anymore, they are simply RTA's with the tank on the bottom but they are not used for dripping so technically shouldn't be called RDTA's) is Cthulhu latest offering which brings us an internal domed chamber inside the sleeve and airflow inserts that can be changed on the fly. Coming with both a standard and BF pin, short delrin and longer Stainless Steel 510 drip tips and both a glass and poly-carbonate tank section let's give the Mulan MTL RDTA a look!

Aesthetics
The Mulan MTL RDTA comes in cardboard tubular packaging with the atty itself being placed inside a little pouch. I received the Black version but there is also a Silver option, it comes with a shortish delrin MTL drip tip installed. The Mulan is made of 304 Stainless Steel and comes with a glass tank installed, we have a short tank section at the bottom then much larger metal top section as this is where the deck is housed. Halfway up the top section we have a groove that encircles the sleeve making it look like it's in 2 parts but it's purely aesthetics as we have a one piece sleeve. Underneath the groove we have a 2mm airflow hole and the top of the sleeve tapers to meet the drip tip. Moving to the base we have printed branding and safety marks, the Silver plated pin which comes pre-installed is a standard but a BF pin is included. The build quality is very good and certainly the finish on the Black version i received seems durable and in general there is a retro look about the Mulan.

It's Various Parts and What You Receive
The Mulan comprises of drip tip, sleeve, deck section, tank and finally the base with 510 pin. The mulan comes pre-installed with a delrin drip tip, glass tank and Silver plated standard pin but included is a longer Stainless Steel drip tip, s poly-carbonate tank section and a BF pin if you prefer squonking. The Mulan utilises airflow inserts and as well as the one installed you receive 2 extra (all have different size airflow outlets). You also receive spare o-rings and screws, screwdriver and an allen key for the BF pin but sadly there is no cotton or pre-wound coils included which is a pet hate of mine when it comes to rebuildables (It should come with everything that is needed to do at least one build).
___________________________________________________________________
Airflow Inserts
The Mulan utilises airflow inserts that can be best described as a piece of pizza, removing the insert is like removing a slice from the whole pizza (the deck) and inserting one completes the pizza.
The inserts get secured by screwing them down from above, the screw is to the outer of the insert so fully accessible while a build is in place and the insert can be removed and slid in place without disturbing your build so you can swap inserts on the fly which is a big pro.
The air enters the insert through a side hole which is 2mm on all three inserts, it then travels through the insert until coming out the outlet which gets positioned directly underneath the coil, these outlets are what differs on each insert, the outlets are 0.8mm, 1.4mm and 2.0mm.
___________________________________________________________________
The Airflow
The airflow is part controlled by turning the sleeve to adjust the airflow alignment but is mostly determined by which insert is fitted, the 2mm airflow hole which is on the outer sleeve needs lining up with the airflow hole (also 2mm) on the outer edge of the insert, of course when perfectly lined up that's the airflow fully open but this can be micro managed. The air then travels through the insert and then up through the outlet hitting the underside of your coil, not having an insert in place isn't an option with the Mulan.
Looking inside the sleeve we can see an indented section on the sleeve which gets lined up with the fitted insert, this needs to be lined up for the sleeve to fully fit and then once in place it gives just enough play for adjusting airflow before acting as a stopper.
Even more interestingly instead of just having the outer sleeve as expected we have an inner domed chamber attached to the inside of the sleeve that sits over your build giving both a very reduced chamber but it also protects the outer sleeve from getting hot.
___________________________________________________________________
Filling
I personally used the Mulan with the BF pin but did initially fill the tank. The fill port can be found on the deck and on the opposite side of the deck we also have a tiny breathing hole. The fill hole is not very big so some nozzles will be an issue my only advice would be to take your time when filling or decant to a needle nose bottle. When using on a BF device simply squonk to keep the tank topped up, the liquid comes out of holes either side at the top of the pin just before the deck section.
___________________________________________________________________
The Deck and Build
We have a 22mm deck which like the atty itself is quite retro looking. We have tubular posts side by side so both leads need to face the same way which get fed through round terminal holes one in each post, the leads get tightened from above with philips grub screws. With your leads thread through the terminal holes just hold the coil in position while tightening the screws. After installing the coil you can use a coiling rod or fit for purpose tool to position the coil exactly where you want it before then making sure your screws are still tight then snip your leads.
With these top coiler atty's people have their own way of wicking from having the wicks feeding down to the bottom of the tank to the other extreme like how i wick just poking my wicks slightly through the ports, just stick to whatever works for you! I did 2 builds, one round wire and a fused clapton build and both builds were easy enough.
