My town hardware store does not carry nichrome or kanthal wire. There is one question that i keep asking and that is what else can i use besides these two? no real answers yet, but i can tell you that copper on any gauge or raps simply will not work. i have heard a little bit about using silver wire, gold wire, guitar string wire, and even very thin stainless steel wire. im not attemting to try anymore because i finally found out that this can blow up your battery... And i dont want to do that haha. so if anyone has some experience experimenting with this, please let me know if it will work. also, i am trying ro modify my v pro protank 2. any advice? thank you and your comments are most appriciated!
