hey, glad to hear you acquired and like your new VTC & Tron tank kit
of course the 'stock' coil is vertical while the CLR is horizontal
I don't have a problem like some do with the oil on these units
they are metal and who knows how long they might sit on a shelf...
if you still wanna try your stock 1.0Ω coil, allow it to soak in Vodka/PGA for an hour or so
then rinse it and dry for a day or so...
yes the .5Ω air draw is much more than the 1.0Ω
(3.5mm vs 1.8mm)
what I like is to pull the 3.5mm pin and insert it into the 1.0Ω coil,
but mostly I build 1.3Ω coils and use 3.5 hole pin...
from my use, I don't care for the stock vertical coils
(but they at least work)
if not for the CLR coils I'd found another tank
will get a Tron version here soon...
