troll rda questions.

[aalmosawi]

i just swapped with a friend and acquired a wotofo troll rda.
and while i love the velocity style design i noticed a few things.

(1) it seemed he had loosened the contact pin bottom side as he had said because he wanted it to make contact with the wismec dna200.
while screwing my wire in the hole center pole just rotated.
are those two connected? is this why it rotated?

(2) the top cap that comes off so you can do the work and drip is VERY easily removable. it seems it has absolutely no grip on the o-rings. Solved. Changed o-ring to one from velocity

anybody?

Most likely. I have an old Mutation Xv2 that had the center post start spinning, a short time after that I noticed the bottom pin was lose and rotating. Tightening it helped, but mine was so bad it still spun. I would suggest you hold down the center post in the position you want it and very gently tighten the bottom pin until it doesn't screw in anymore. Make sure not to use a lot of force, just like 2 fingers strength, and get it nice and snug. You can use the rda like that, but spinning center post will just be annoying.

ya it is annoying. i traded with a friend and got this from him. gave him my hated (by me) wismec indestructible and obtained this.
he had loosened the pin to make it reach the dna200 or something ... anyways once i tightened it it seemed to be ok now. i even noticed the o-rings were so weak to hold the top cap.
i used an o-ring from my velocity clone and it made it a bit hold much better. the o-rings they supply are too thin and once juice hits them they are useless.

I agree that many RDAs have crappy o-rings. They also give out after use, so the more the cap is pulled on and off, the worse they get. You could check a hardware store for o-rings, they might carry the same size. Other than that would be to get some calipers and measure the deck of the RDA and get some o-rings that will fit the width of the o-ring groove and be a little bit smaller than the RDA. I have a velocity clone too so I could measure the o-rings for you, then you could look them up by size on ebay or something. I know fasttech might have issues, but maybe it would work for just some o-rings.

no worries. tooth floss wire works wonders under the o-ring to keep it in place.
