American company AVID have introduced a new 1-piece carbon fibre wing button for 1/8 buggies including the HB Racing D819, Team Associated RC8B3.1, Kyosho MP10, Mugen MBX8, Serpent SRX8, SWORKs S35-3, Tekno RC NB48.4, TLR 8IGHT-X and XRAY XB8 ‘19. Made from high-quality carbon fibre, the carbon 1-piece wing button is a cool alternative to the commonly used wing buttons and helps work as a template to mark your holes in new wings.
