thanks for the posts mates .
I want to take the time to give a small update for the moment , nearly everything is in the house and I finally decided to get both the Kennedy RDA and the Dejavu RDTA ; I'm amazed by the quality and the look of these two little objects of divination . They are very little maybe my big hands who knows ; the steel tube gives a good feel in the hand, but this also is not as big as I figured out .
You may have noticed I've not been in a rush lately , it's for the fact I'm very busy ; while I have nearly everything at hands I will stick with my pen ecig for a while more
One two things I may ask , in general , about coils and mech mod builds ;
if I've read and understood well - there are literally hundreds configurations and vape results for them - , on a mech the coils should be pretty simple , I will have to work with 2 coils as for my atomizers , I will need some quite low resistance i.e. 1ohm x 2 for a total of 0.5ohm roughly, or anything over 0.2ohm which is safe for a mech mod- this in order to have a decently short time to produce the vapor, and have the right heat for vaping (?), and I will also have to find the right dimensions and size in coil diameter and n. of wraps in order to provide a decent surface for the cotton contact .
Speaking about mech mods , that is : about one 18650 4.2V battery power :
for what I understand a fast instant 2-3 seconds short good dense vape can be had only with low ohm , and to produce a right amount of vapor and flavour it needs a quite wide surface of contact in this case (?), resulting in quite big diameter (>3mm?) and stil decent number of wraps (n.? depending on diameter)
or did I get something wrong?
Thanks for your input.
