What is the advantage to having long legs on your coil?

[bushmaster]

I may have asked this before but as many of you know, my mind is going, so bear with me. I notice the coil gurus have the coil extended out near the barrel of the RM2 whereas I usually pull mine in near to the posts. No reason--just don't know any better, I guess. What is the reason for extending the coil out toward the perimeter?

I originally started doing it because I liked to experiment and with the longer legs I could straighten them back out and reuse a coil if I liked the old one better then the new one. Another benefit is sometimes the screws loosen up and if you bend them over the top and tuck the end into the screws it acts like a lock to keep it from loosening up very much.

Technically, you do not want longer legs to a coil. It is wasted resistance, since it is not touching the coil and will add heat to the atty.

However, with the RM2 and other bottom fed attys for the REO, you want your coil to be very close to where the juice is fed after you squeeze the bottle. In the case of the RM2, there is a hole in the bottom of the atty where the juice comes from. I suspect that is why most builds you have seen have longer legs than most other RDAs. With something like the Vicious Ant Cyclone, the juice is fed through the center post, so there is no need for longer legs.

OOpps I read that wrong I guess.

Actually, the point is to get the coil close to the air hole. This increases air flow over the coil and promotes increased vaporization of the e-liquid. Adjusting the height of the coil above or below the air hole can change taste and TH as well. Coil placement can also affect the draw; either tighter closer to the air hole or looser further away.

swap 'coils' for 'women' and you get different resistance and answers.

the reason is that it will allow you to raise and lower the same coil without having to remake one, because the position of the coil in relation to the airhole (and the size of the airhole), will determine how much flavour v throat v vapour you can get from it.

If you use low resistance wire in the first place then the final coil resistance will not differ much, but where that coil is in the chamber will affect your vape. The golden rule seems to be to raise the coil to make it harsher and lower it, in relation to the drilled airhole, for more flavour.

i am not talking hi tech here - lower coil = stuff finger on it and push it down!

I believe the main reason for extending the coil all the way to the edge, is to get it right up close to the airhole on the cap. Better flavor.
You do have to be careful that the coil wont touch the cap when screwed on, but as close to that airhole as possible. Hense the long sexy legs...

Okay, I'm hip to that. So the longer legs give me more flexibility in lowering or raising the coil to my taste preferences, right?

Yep, that's why I run longer leads, to place the coil right up against the air hole. I get them so close many of you would probably be scared of shorting. My coil is so close to the air hole I can see how dirty my coil is just by looking through the air hole. My coil is so close to tbe air hole that sometimes vapor shoots out the air hole when I fire without hitting it. My coil is so close to the air hole that I can use it as a flashlight when I'm dry burning.

But be careful. I use the flat of a small screwdriver as on the fly coil adjustment can equal burned fingers.


Not that I've ever done that.


Honest.

Ditto. I like to dry burn my coils with the cap on before wicking. If I can see the glowing coil through the air hole I know I'm good.

in any kind of coil building, it bears repeating, the longer the legs the higher the resistance…. keeping a long leg, with a tad protruding past the screw head (on the unused side; ergo no current) you can loosen the nut and readjust the coil position and for less or more reisistance shorten or lengthen the leg length (on the coil side of the posts).

yep - it's room to play a little.

I, too, have vape clouds coming out of the airhole...I love it!

But when I don't have the airhole away from my lips and I draw on the DT I get my little chinny chin chin tickled!

I wish i had long legs because then the top of my fridge would be easier to clean. Oh wait, its coil legs not girl legs.

Although it isn't as critical with the RM2 because it is hard to flood them I use the vapor coming out air hole and DT to judge proper amount of juice to squonk on hot coil, to keep from flooding other top cap hole RBAs like the Hornet and ERA. I've never had an RBA coil pop juicing a hot coil. I don't do sub ohm so that may make a difference in how little the coil and juice are affected squonking a hot coil but not sure.

I've stopped using the button cover on 14500 Mini using RM2 because It puts my finger too close to cap hole and burns. And I don't have fat fingers.
