3 MM heat shrink. Used with the small wire on the mini V tail motor wires.

I used this 3mm heat shrink to cover the solder joints on my mini tricopter between the ESCs and the motors. It worked very well for the small sized wire (14 or 16 gauge wire I think). It shrunk up tight instead of a little loose like the larger size I had been using.
