Well, That Was A Fail (Little Boy RDA + eVic-VTC Mini)

[vuJim]

Stopped at a local tobacco shop & vape store on the way home. Bought a Little Boy RDA on the recommendation of the proprietor. Unfortunately, the 510 connector is way too long. Even with a bit of moderate tightening: The bottom of the deck is well off the top of the mod & the thing is wobbly. Too bad. It looks like a neat little RDA.

See if you can run the 510 pin on the little boy further in to let it thread down further. Sucks to have a new atty and not use it

Way ahead of you. The pin is tight. Does not turn.

 

[fq06]

That sucks, was worth a mention at least.

Maybe it will work on the next mod you wil inevitably buy... maybe sooner now

Lose the ability to adjust and probably plating but tighten it up as much as possible and sand that sucker down?

 

[martinelias]

Never had problems with it though i never used a evic. Is the contact on that mod spring loaded? Ive had problems with 510s being too short like the odeon rda but never tooo long. Sucks dude. You tried it on any other mods?

I don't have a Little Boy RDA, but I've a few attys and none of them have a 510 post that's as long as what you describe vuJim. Assuming you've tried other attys on the mod and it's not the mod's 510, I would take it back to the shop and show it to them on your mod. If it's too long they should replace/refund for you.

Good luck with it.

It was. Thanks for the suggestion

Thing is: I rather like this eVic-VTC Mini. I've yet to have needed more than 50W. So unless somebody comes out with a dual-18650 or single 26650 mod that's as good, I'll buy another.

It doesn't appear it's meant to adjust. However: We have many talented people and a milling machine at work. (Plus I have a friend with a CNC and lathe.) For the whoppin' $15 this thing cost me: I'm thinking of seeing if I can fix it. Worst that can happen is I'll be out $15.

I believe it is. I don't want to push on it hard enough to find out, the hard way, it's not.

Other people have had this problem with the eVic-VTC Mini. This is the first time I have, tho.

Only other mods I currently own have eGo connectors.

I've had three tanks, from different manufacturers, and an eGo<->510 adaptor on it. This is the first time I've had this problem

The shop probably will refund me or give me a store credit. But this one-off shop's owner has spent a good deal of time with me. Other than the initial, entry-level purchase and a bit of juice, I've had a hard time finding things to buy from him in return for his investment. So, for the $15, I'd really hate to return it

It's not so much the $15, tho $15 is $15, but more a case of: If I can't make it work it'll just sit around wasting space.

Thanks for the feedback, all!

ETA: I guess it's back it goes. A colleague at work and I just examined it closely. The problem is two-fold: The screw is stopped from going deeper into the atty by a shoulder in the insulator. It is possible, with great care, to make that shoulder ever so deeper. But, eyeballing it, it would appear that even if the screw head was made flush with the outer part of the 510 connector ("ok" on a regulated mod--exceedingly dangerous on a mech mod): It would still be too long.

I have two tanks (Triton V1 & Kanger Subtank Plus), that wobble on the VTC Mini, due to being unable to mount them flush to the mod. I compared the length of the 510 connections on those tanks, with the once that do fit. The threads on both tanks were slightly longer than on the other tanks (ca. 0.75 mm). A while ago, I saw a video review, where the reviewer also had a problem with a certain RDA not sitting flush. If you try to tie it down harder, you may encounter a problem I found out. It didn't fire. I had to loosen the tank, and screw it back in, just the right amount (w/ wobble), in order to be able to fire.
IMO, Evic didn't give their 510 connection enough room, in order to be able to mount toppers flush, that have a slightly longer 510 connection. BTW, it is a spring loaded pin in the 510.

This implies that over-compressing the connection causes it to open, internally.

I'll see what the store owner says. If this turns out to be a problem with RDAs & the eVic-VTC Mini, in general, maybe I'll try altering the RDA, after all. Like I said: Worst that could happen is I lose my $15 investment. And, if it works, well...

If you decide to alter the RDA, I would shorten the screwed in pin, and the outer threads of the RDA's 510 connection accordingly.

 

[Neunerball]

Out of curiosity, I took five of my currently 61 RDAs and screwed them on my VTC Mini. With the exception of a Baal clone, all other RDAs fit flush, and fired as well.

Using the paperclip-as-a-measuring-tool method , I found the threads into the center post extend more than far enough that altering the length of the screw will not be necessary.

But the over-all length of the 510 connector... that's another ball o' wax. Shortening that will disrupt the starter thread--which may make getting the RDA on the mod tricky, or could even result in cross-theading.

61 RDAs... wow. Good news, anyway.

He had other RDAs. Probably more expensive. I think I'll talk to him, first.

He needs to know about this problem so he can send the others back .

TBH: I suspect the RDA was built this way on purpose, to guard against shorts on mech mods.

 

[fq06]

I doubt he is going to send any attys back just because it has a fit issue in one mod. Maybe let him know that atty and others he may have with a long 510 will have fitment issues with the vtc mini.

I know the super tank mini barely bottoms out on my wifes vtc mini so it's not just that little boy. He can save his customers a little $ and direct them to an atty that will fit if he asks what mod they have and the answer is vtc mini... knowledge compliments of you.

 

[vuJim]

He checked it out, asked "What do you want to do?" "Do you have another RDA you can recommend?" Grabbed a red Plume Veil clone. Unfortunately the threading was a bit out-of-whack on that one and it didn't want to go on, but the black one did--just fine.

He threw a coil into it (probably to make sure it'd fire), wicked it, looked at what he had open on the shelf, grabbed a bottle, thought a second, asked "Have you tried the peanut butter?" "Nope." Put bottle back, grabbed another, juiced the wick up and it works like a champ . Doesn't have the big chuff tip, which is just fine by me, and has a bit nicer build deck, IMO. (4-hole instead of three.) "Whatta I owe ya?" I asked. "Nothin'. We're good." Gotta like that.

 

[fq06]

I much prefer 4 hole, especially with a TC mod... you're not using 20g or anything thick like that any more.

Sounds like a great shop to have near you, congrats on the plume!
