Hello again sooo I tried my first rba a kayfun orchid clone.at first I couldn't make proper coils so I used premaid to get to .8 resistance to use in my mechanical mods with defeat batteries 18350 and 18650.at .8 the orhid worked perfect hearing up almost instantly.but I don't want to use premads coils and want to learn to make them myself I got my 28 gauge kanthal cotton and everything needed and started.but to no avail..I downloaded vapers toolbox and it said in order to get to a .8 with 28 gauge and 2.5 mm size coil I had to do a 9/8 wrap. (For dual coils.)which I did but the resistance was 1.1 so using the on my mechs doesn't work as they take toI long to fire. So I use it on my istick now but from time to time the resistance changes from 1.1 to 2.2. right now it's still 1.1.anyway and sorry for the long post .does anyone have any advice as to what coils to make to vape on my mechs mostly?? And why the app said I would get a .8 I got more? Thank you!!
