Rdna 40 question

[noideawhatimdoingqq]

Since i don't have enough posts yet to ask on the respective subthread figure i would give it a shot in here in case someone experienced comes around.

I just recieved a vaporshark rdna 40 and the ni200 occ coils for the subtank mini, i plugged it in, started reading it at 0.20 ohms and then after eating it was set at the correct 0.15.

Right now i', running it in the low 20w and have the temp set to 420F, when checking on the mirror i see the watts dropping a bit so guess it's hitting the temp control, i mean the flavor is good and vapor too (a bit less than my istick 50w) but then again it's also not so scorching hot.

Just wanted to know if that sounds like it's normal, guess i would have better luck with the rba base or an rta, could someone recommend me a good rta with good clouds/flavor that works nicely with the rdna 40 and nickel?

Thanks

From my experience the pre-made coils for the sub ohm tanks do jump around a bit. Don't forget you have a feature called "Atty Lock" which allows you to lock the resistance reading. If you need helping activating it, while your in TC mode hold the up and down buttons at the same time. It will show "Atty Locked" and it will stay at the set resistance you have showing on your device. As far as RTAs are concerned no idea for you there I'm still on my baby steps with them myself.

The coil in the subtank can take much more then that. Try setting it hotter maybe around 500F and boost the wattage up as well. You'll notice if your getting temp protection as it'll throw it up on screen and adjust wattage once it does. It'll be like a pulse so it won't over reach your temperature wall you've set.

Thanks, going to test it right now

The DNA40 chip will pre-heat, fire above your set wattage, then maintain the temperature you have it set at. That means the chip is constantly fluctuating the power (if it needs to), so seeing it dial back the wattage is normal. What you don't want to see is the "temperature protection" message. That isn't necessarily a bad thing, it is doing what it is suppose to, but it means it is drastically cutting the power to the coil, rather than simply dialing it back.

I would recommend setting it to about 28 watts and 450F and see if you are able to get a full draw without the "TP" message coming up. If so, and you want to, you can gradually bump the power up until you do see TP, then back the wattage down just a bit. At that point you have found the "sweet spot".

Some people like a bit warmer vape, so they bump the power up to say 500F, which likely also gives more flavor, then play with the wattage to find that spot. 450F is the average flash point for [dry] cotton, so most people tend to stay at or below that.

Thank you very much, will try that , think i only saw the tp message once and the tank was drying up.

Now guess i just need to find a good rta to play around with .

I have the same setup I found my sweet spot at 510f @ 18-20 watts.

Cheers will give that a go too and see how i like it , thanks!

You may get a little crackling at first but it will fade.

I'd suggest the Eleaf Lemo 2. Great single coil RTA, lots of airflow, top filling. Works well with regular Kanthal coils or NI200 coils.

Should be able to pick one up for $30 or less. I just got a second one for $23.99 during the Memorial Day sales.
