The thing about subtank that people did not notice is that you need to screw your RBA / OCC to the base before screwing on to your mod. If you screw the RBA/OCC to the base with your mod then the center pin will fix to your mod. The center pin on the base is adjustable.

Which part? If SvoëMesto don't sell it then we can help you.

Sorry bro. SvoëMesto also don't sell that. I guess you still can use the plastic tank.

I have an authentic one. Cloud, definitely! Flavor, yes with kanthal. Nickel, ok. ok.
Had mine on 28g nickel, dual coil 0.08-0.1ohm on vaporshark rDNA40, firing 40w, 210c. Although firing at 40w, still cool, warm smooth vape.
I had a clone too but use once then put aside collecting dust. leaking, cannot get stable ohm reading on nickel. top cap loose.

3mm diameter 9 wraps each. tried 8 wraps, still get 0.08-0.1 ohm.

I have both.
Derringer - more flavor, tighter draw, mouth to lung/direct lung, shallow juice well, single/dual coil.
Velocity - flavor better then most dripper, easy to build, deep juice well, lots of airflow option, cloud machine, direct lung only. Single coil possible but airy and less flavor.

Screw the RBA base bottom screw to tighten L shape post.

The secret is the heat flux & heat capacity. Heat flux is how hot is the coil will generate. Heat capacity is how fast the coil heat up to reach the heat flux.
Dripper and tank are totally deferent thing.
Tank, has limitation due to air hole and juice hole.
Dripper only limit to your wicking material.

I use my tank as a benchmark. For example, on a kayfun, my typical build is 28g, 1.5ohm, 2.5mm, 11w, my heat flux is 158 and my heat capacity is 22. So when I build a dual coil or a lower resistance coil, I make sure my mod match the heat flux & capacity. The heat flux must can go above 158 and heat capacity must not more then 40.
If the heat flux is lower then 158 then I get a cool vape and less flavour.
The the heat capacity is more then 22 then I need to press longer the fire button the get the flovour heat that I want. The longer you press the fire button, then more the battery power is wasted.

Anyone interested authentic velocity RDA can PM me.

Suspect spring issue. Even the authentic with silver spring have this issue. That is why SvoëMesto come out gold replacement spring. Now all the new set come with gold spring. no more silver spring.
