I have been using the kraken rba for a good few months now and have a few good tricks to help people build them. I have posted a few in some previous posts but thought I would start a new one with them all in.
Firstly if using a mesh wick cut it about 1.5cm wide then wrap it round a straightened out large paper Clip so it makes a small tube. Heat it up with a small craft blow torch, next drip your juice onto it then set fire to it and let it burn do this 10-15 times it helps get rid of the burnt taste. I put some cotton around the top so when you put it in the coil it is reasonably snug. I also put a small amount down 3 quarters of the wick just to make sure it doesn't short on the side of the wick hole. I usually build a 1.4 ohm coil and put a 2mm drill through it and into the hole to keep it in place, I connect the top post first so the coil is level with the middle post screw then connect the bottom this helps it wick and burn better. I normally use a single coil but a dual works on the same principle
