3 ATTYs, similar ohms, 3 differences in flavor! WHY?

[Fisheeboy]

When I first got my dripper I built a 2.1ohm coil and all was well. When I received my KF clone I decided 1.5 was just right. I even rebuilt an iclear16 at 1.5 and it is just right. Two toppers at 1.5 ohms and I'm pretty satisfied. So I built the same coil for my dripper at 1.5 and it just doesn't do anything but burn the liquid. I get better vapor and for sure better flavor from the iclear16 I rebuilt. I get great flavor and vapor from the KF clone. Why is the same coil no good in my rda?
I should be getting better flavor with dripping than with a rebuilt iclear shouldn't I?

A little more info please. What type of rda are you using? Perhaps the air hole is not lined up properly.

 

[State O' Flux]

It's all about balancing air flow to coil heat, atomization chamber vapor condensation, wicking capabilities... and applied voltage. What works in one, or two atomizers is not necessarily the correct combination for all atomizers.

You may think you have a great set-up... until you try a really great set-up. ;-)

I have this one SMOKTech RDA Rebuildable Atomizer It's what seemed like the best choice for a beginner. It has a tight draw much like the iclear16. It's a cheapy and a pretty poor design so I can't really make the airflow any better because there is really no way to enlarge the airflow holes. The thing that got me scratching my head is that I'm getting better flavor with the iclear16. But they have an almost identical draw.
I'm using the same voltage setting for all three ATTYs and the only one that burns is the rda. I keep the air holes aligned.

I have that RDA. The trick is to make sure that the air hole is lined up directly in front of the coil. If you could see through that tiny hole, you would only see the coil. Make sure the coil is not too high or too low. It needs to be at the same level as the hole.

Maybe I have the coil too high. I'll push it down closer the the air hole.

 

[doots]

might try lowering the coil or raising thr coil and see if that makes a difference. most assuredly it will.. its always about airflow and coil placement to the hole..

 

[finagle69]

The lower you go in resistance for a dripper, the more airflow you'd want. In general. The idea is that lowering the resistance is raising the power.

 

[Fisheeboy]

So I pushed the coil down to were it is just barely above the air hole and it did help. But still lacking in flavor. I've tried several different wicks also. Maybe it's just as simple as going with a different coil. But I tried that too. Even going back to a 2.1 and it still burns the liquid. I'm using 32g kanthal. It's all I have on hand. Maybe a different gauge would help?

Different condensation ratios and heat = different flavor every time.

To make sure I have the coil at the right height, I hold the body right next to the base. Actually resting on the lip right on the edge of the base, with the air hole right next to the coil. Then I raise or lower the coil to the proper height.

True. I actually slightly increased the size of the air hole to increase the amount of air hitting the coil. If there is not enough airflow, the coil gets too hot and burns the e-liquid and or wick.

I use this RDA for tasting new e-liquids a few drops at a time.

 

[Fisheeboy]

Sounds like I may just need to keep tinkering until I find that sweet spot. I will keep trying different coils then.
I really do appreciate you guys taking the time to help me out. I just ordered an IGO W this morning and I will relatively soon have a mech mod and I want to get as much experience under my belt as I can. I don't want to be that guy that gets in over his head and damages something or someone.

 

[HazMatt]

You want the coil directly in front of the air hole, not slightly above. The air is coming in from the side in a straight line. It the coil is slightly above the hole, some, if not all, of the air is missing the coil. You want as much air as possible to hit the coil.

I prefer 30g in these small RDAs but, 32g is fine. I build coils in the 1.4 to 1.8 ohm range. I use them on an eGo twist for taste testing.

HazMatt, how did you increase the size of the air hole. I wobbled a paperclip in the hole of the aluminum sleeve and it's counter hole and it did increase the diameter but how to increase the hole diameter of the hole under the coil alludes me.

 

[Fisheeboy]

The air hole on mine actually is not flush like this one here. Mine has like a mettle sleeve so it comes up just a bit from the base. That's is what mine looks like.

I found a small hand drill set at the local hobby shop. It came with a dozen different tiny drill bits. I think the largest was around 1/32 inch. It was exactly the same diameter as the hole. I twisted the drill while pressing left then right on the sides of the hole. I did not increase the height but I did increase the length of the air hole. It is more like a tiny slot now.

Your RDA has two air holes? Mine only has one. I guess they are not the exact same one then.

 

[HazMatt]

Oh, it looks like yours has bottom airflow. Mine has the air hole in the side. My apologies.

ops, forgot to resize

 

[Fisheeboy]

I bet I could add another hole to the aluminum sleeve that would bring the air in directly beside the coil. It shouldn't be too difficult.
I don't think I would ruin it if I tried lol why not? I'm gonna see what happens.

 

[HazMatt]

See the picture I added to my previous post. This is how i check to see it the coil is at the right height. It is easier to do with both hands lol.

LOVE it! thanks man, I think another whole will help. I will start out with a very small one and work up till it's good. Besides, it was less than ten bucks and it's served its purpose and I have that IGO W coming so I can afford to do some experimenting.
