Tengu RTA by Tark - Mod N World

[musicman21]

@Marc411 @Mtek @TheotherSteveS

So I just received my Tengu v2 back from tark. Came back immaculate. juice control works excellently. No more scratches on the barrel. Super pleased. EXCEPT.... I went to go clean it out again. Went to take out the post screws and...ahhh. One won't come out. Too afraid to apply the most pressure I can to it for fear of breaking the delicate base. Other screw popped out just fine. The guy did such a good job with taking care of it and I'd like to solve this 1 issue on my own if I could. Does anyone have any good advice to help get it out!!? Such an utterly ridiculous little problem. I really would hate to have to return it for this quick fixer upper....If it is quick.

Just got a Tengu V2 from an original owner. It is definitely worth the price in my opinion. Flavor is great & I love the airflow. Using ni200 at around 0.074. I did have some flooding to begin with after I turned the JC a couple of turns. It didn't seem to be that much though. I may have not used enough cotton

 

[TheotherSteveS]

The JF is a bit of a pain. I have had the same experinece. Half a turn is enough but it is a bit loose and turns a little every time you vape it and then, eventually, it floods! Great vape machine though!!

I rewicked just now with more cotton & everything is working perfectly so fat. Does anybody know a fix for loose drip tips? I have 5 total & only one fits.

Do you have a lot of hexagonal cross section DTs??

 

[Unior]

I am not sure if I know what those are? Unless they are the ones that came with the Tengu. In that case I have 4.

 

[TheotherSteveS]

The cross section of the top of the chimney is hexagonal right! The drip tip is the same so when you put it on you can rotate the chin to control the juice flow! It won't take just any DT. That is another issue with the Tengu!,

@Bricca @Marc411 @Mtek @TheotherSteveS Guys any recommendations for a stellar wick method for the tengu? Finally have gotten everything in order with it, and it's finally cleaned. Nice looking little build inside of the thing, yet it has now emptied on me 3 times. I'm not going to bother again until I get some crap juice to put in there or get some good recommendations. Tried having the tails of both ends just touching the bottom of the base, maybe a little more than touching. Then fluffed it out so that it can be dispersed to all 4 wick channels. Now do I want to really fill in those wick channels with fluffy rayon/cotton, or just have them barely touching the openings?

It worked one time for practically ten minutes and I was practically the happiest camper this side of town, but then I saw that the top cap was offset, screwed it off, flipped it upside down for 1 second only to get top cap off to screw back on appropriately. Then 5 seconds later, the juice starts flowing from all those little holes on the bottom. Ahhhhhh. Help would be appreciated.

Just received the Tengu (Thanks Much Unior my Brother!) in the wintery Vape-Mail. Slapped a single Ti 26ga, 6-wrap (came in right at 0.28R) on a 2.38mm Bit Coil on 'er and wicked it up (typical Pancake Method). Filled it up and opened the Juice Control about a 3/4 turn (70/30 Liquid) and exposed 2 Air holes on each side (prob go to 3 after Coil break-in). Attached to a Asmodus Snow Wolf 75 mini TC, set to Ti Profile and 444* F, then lit the Fires....
Mercy Sakes does this Flavor Beast ROCK

I love my Erl Ks and the Bellus is a great RTA but Gents, this thing may have just stole the Crown. For the time being, there's a new Command Sergeant Major at Ft. Vape. His name is Tengu

 

[Hitcat44]

Well, after 3 days of being snowed-in here in the West Kaintuck by Snowmageddon 1 of 2016 Still diggin on this Flavor-Beast.
An observation with points/questions for experienced Tengu Owners to consider and advise if I may:

1-The Juice Control/Flow/Feed is a touchy, sensitive, and fickle Deal. At times 3/4 open is the Ticket (70vg/30pg Mix), then she may flood a tad (ooze a bit out the Air holes), then sometimes 1/2 open is the Ticket for a spell then she runs lean tripping the Dry-Hit Power Limiter. Directly after refilling is when she gets schizo for a bit. Obviously, I do close the Juice Control off completely before refilling only opening it after done and the Top Cap is reinstalled and tightly sealed. Possibilities:
a. Due to Design, the spinning of the Chimney Base when adjusting/closing it off and opening again possibly moves the Wick around exposing more open area allowing more liquid to enter and partially flood the Chamber. Solution: Open the Juice Control less directly after Refilling?
b. Just the Nature of this RTA and the way it Gravity/Vac feeds. The more Liquid present in the Tank-the Easier & Quicker it force-feeds Solution: same as above.
c. Little of Both.
d. Wicking needs some tweaking. Although after reading Posts, watching the only Review/Tutorial Vid on the Web, and drawing from experience from other similar designed RTAs I thought I had it pretty much nailed,,, I could be mistaken.

Of course, finding the "Sweet-Spot" is the Eldorado as when she is really wet and right on the edge of gushing (no puns intended) is when she is at her best for Rich, Warm, Flavorful Vapes.
Given that, maybe I just need more time, fiddling, Trial & Error, etc. to find just the right combo for the Tengu and my particular Liquid and Settings.

The Drip Tips are indeed a tad too large in I.D. (an over-tolerance) which allows it to easily come off when vaping or carrying in a Holster. My solution was the old Vapers Duct Tape... Teflon Plumber's Tape. About 3 rounds and it slips on tautly and does not come off undesirably. Then again, most of you are probably reading this and thinking; No Crap Dummy

Other than that, the only Issue is this thing is just so damned Awesome Floavor-wise it is making all my other RTAs (which are actually still quite good) Ride the Pine more than their fair share.
I guess that is to be considered evidence of a wise Investment yielding better than expected Returns.

Steve, switching out the O-ring in the top cap where the JFC comes through will stop the loose spinning of the JFC. I think it's an 8 X 1 mm but I'll have to check when I get home. I did both of mine and it fixed the problem. It's a real PITA to get them in that little slot.

musicman, that deck loves cotton and I loosely fill mine just about to the top. It's surprising but a little bit goes a long way on the JFC and there is a sweet spot, once you get past it you'll get leaking.

If you saw how much cotton went on my deck you would be surprised. When I first picked mine up and had leaking so I talked to Tark and he said not to be afraid to fill it up and he was right. Just watch the wicking around the coils and the air holes on the deck because you can choke the air flow with your wicking. I use a 2.5mm coil and the airflow is pretty damn good.

 

[Hitcat44]

Hmmm,,,
Thanks for the Post Marc. Answers my question as well. I would say my Issues are caused by going too light on the Wicking Material and having a ways to go to discover just the right Setting on Juice Control (after correcting the Wick Volume). I will just deal with it till time for a tear-down reBuild then address the Wicking and attempt to switch the O-ring in the Chimney pass-thru on the Top Cap at the same time.

 

[Marc411]

My pleasure Hitcat, cool avatar. It took me a second to notice that the little guy (or girl) is being naughty.

Checked my spreadsheet and here are the O-ring sizes:

Chimney pass-thru top cap 8 X 1
Top cap threaded 17 X 1
Top cap juice fill (internal) 16 X 1
Base 17 X 1

 

[Hitcat44]

Naughty? Naw, he's just "mousing" (takin down the "Rats" so to speak) in a more productive, efficient, and clean manner. Smart Kitty

Day off tomorrow so will take-down the Tengu, check the Coil to gauge re-Coil Intervals, then re-wick properly per your Direction.
Then rebuild the Erl K, then,,,,,, I find such to be highly Therapeutic

sounds like a good days work to me!! Go to it mate.

ps. I second the cotton thing. The more the better up to a point! Also, the JF is a bit finicky but I found that as long as its not fully closed, or so open it floods, it just works. With a more demanding build it might need a bit more finesse but for my 6-8 wrap Ti coils, wicking is not a problem!

 

[Hitcat44]

That's my Standard Build too. ti 26ga 7/6 wrap on a 2.38mm I.D.
Will do a standard Pancake flared Wicking as before but skip the Thinning finish. Then start the JF at about 3/4-turn and go from there.
That's part of the Vape Thing, tweaking and honing in all the Parameters of the Atty/RTA to get 'er purring along.
Like fine-tuning a Hot-Rod. Vape Mechanics.

 

[Hitcat44]

Well,,, I think,,, finally success. With a Full Tank and a thoroughly wet Wick prior to reassembly, only have to open the JF about 1/4 turn to keep it juicy and (so far) no flooding or AFC leakage. I imagine I may have to open the JF more as the Liquid level decreases. Could be mistaken about that.
A couple Pics so those of you with more experience and success with no flooding can review, assess, and advise as to possible improvements:
*I did not replace the Coil as it is only a week old. Be appearance (with typical frequency of use) should last 3-4 weeks between re-Coiling.

Any suggestions or critique, fire away

and, did a complete rebuild on one of my Erl Ks as well...

Awesome relaxing Day Off tinkering with Gear, cleaning and refilling Tanks, taking inventory of Supplies, reordering some, and just piddling around in the Armory at Ft. Vape. With XM on Lithium 34 jamming out to good ol' Classic 90's Grunge and Alternative Rock.
Even found time to locate & order the Wife a Kamry Legend V 30 (wood & copper 18650 Tube VV/VW Mod) as she said she would like to return to Vaping with me again(only Zero Nic).

Just a helluva Day my Brothers.

 

[Marc411]

Sounds like a nice relaxing day Hitcat.

Builds look good too. I had to give up on the Erl, I never could get the build to zero in but a friend of mine loves it now.

 

[Hitcat44]

yes twas... Thanks for the co-Sign on the Build. Still needs some final dialing-in but getting there thanks to you and all on this Thread. The EK comes natural for me as I first learned to build and wick on a Fogger v4.1 which employs the same "minimalist" wicking technique Fundamentals. This Tengu is a 180* departure and totally new mentality. Expanding One's horizons isn't easy at first. Especially for an old Routine rutted Cur like myself

But, the freakin' awesome rich warm Flavor is well worth the effort and time. You all were dead-on right and I completely concur with Steve...
It's mind-blowingly amazing
