This wire is constructed from 1,000 strands of bare copper with a thin wall silicone insulation. Only 3.0mm in diameter, this +/- 14 gauge wire fits right between 13 gauge and 16 gauge products to provide an alternative for those demanding higher power delivery with great flexibility. 1/12th scale, WGT and Oval pan cars will benefit from the larger conductor while still maintaining a tweak-free chassis for better handling.
