Decided to try some coil building on my mini pro tank 2. Not going well every time I build one no matter how I do it g get an ohm heading that is too low for my batteries of about 1.4. I am testing them on my pass thru as not to ruin my batteries as have already killed one. I am using 30 gauge kathal wire. Any help appreciated. Tried making them with 1 1.5 and 2 mm coils and with 4 up to 8 coils and they are not shorting. Some of them fire up for a second on the pass thru then they stop if I press the button again it does the same on for a second then stops again. Help please it's driving me insane. Must of tried 20 different permutations. Thanks.
