The RX does temp control with ni200, ti g1, and SS. Do you have another coil with one of these wire types? Or just the nickel one?I just purchased the new Reuleaux RX200 is the Ni duel 0.15 the only coil that can be run in temp mode???? I'm starting to think the mod is screwed up...I'm very new only been va ping about 2 months...please help or I'm running the Uwell crown tank on my RX200. ..thanks
