so without the basic calculations and math and the long cpomputations that looks like rocket science.
this a brief guide in rebuilding...
**note don't blame me if the thing explodes in your face,i take no responsibility.
note a multimeter is required atleast,,,if you have a vamo or any vv mod with an ohm checker that is great.
a few points to remember
the thicker the wire less resistance
the thinner the higher
so if you are doing sub ohms
thick wire less loops
for a regulated mod
thin wire minimal loops or thicker wire and a lot of loops.
please do check your coils for resistance.
battery wise,always get those imr batteries they are ideally safer compared to other types,
if you know nothing on them and refuse to learn on whats already on these forums.better save money ans just buy aw imr's or efest batteries.
they are a bit pricey but thats the expense you pay for neglecting to learn...
air holes are a much needed modification to an rba/or rda simply because it controls the drag and amount of vapoor as well.
you may have a dual coil set up and think that everything is set up right,but having a small airhole would just slam it down per se...
drill them out to a comfortable size..or get those top caps with afc...
now basically there are 2 kinds of build out there,,,
contact coils
and spaced coils
contact coil/microcoil/nanocoil
are practically the same coils they only differ on diameters.
basically you wrap them around a "mold" then amke them all touching.
spaced/normal coils
are the opposite,they are basically coild evenly spaced with each other.
feel free to chimme in...
