Yaiba Racing from Japan have two new carbon fibre option parts for Team Associated’s B4 line of buggies available in the form of a multifunctional ESC tray and a LiPo battery strap. Starting with the tray, the mounting platform for electronic speed controllers is designed to rest on the rear bulkhead of the chassis and allows the mounting of the speedo above or below the tray. Beside being a simple platform the carbon fibre part also offer openings and mounting positions for a large 40mm fan allowing for very good cooling even if the speedo is sandwiched between the chassis and the battery in its lower position. But the cleverness doesn’t stop there. The part comes with an add-on aluminium battery stop for shorty LiPo packs to make sure the controller is perfectly secured and the battery stays in place. The second new part is a 2mm carbon fibre battery plate in short specification for the use with all standard and regular length 2S LiPo batty packs. The part is designed to fit all B4-based vehicles and is useable with the stock or aftermarket thumb screws.
