i have been vaping a RTA setup for over 4 years and been happy building my own coils for them. as well as making my own juices..
As my previous tank had fallen to bits i thought i would try the RDA route..
i purchased the Derringer as my first RDA…
i was using 0.35mm a1 kanthal with 7 wraps ( not sure of size due to using a watch makers screw driver as the wrapping post ) was coming out at like 1.2ohms, this was my sweet spot with the Taifun GT2.
put exactly the same coil into the Derringer and with the current MG of nicotine juice i have it nearly blew my brains over the ceiling.
i have just tried a thinner wire not sure of the size, just had a spare real, but its a LOT thinner.. 8 wraps round the same post is giving me 2.2ohms but no flavour and hardly any vapour.. and if im honest far from a pleasant experience when smoking it.
