RC Car Action - - READERS’ RIDES -

Brett has a knack for Cad-de­signed, 3D-printed RC ve­hi­cles. He is jus­ti­fi­ably proud of his re-cre­ation of Mazda’s his­toric Le Mans–win­ning 1991 Mazda 787B. Brett tells us he de­signed it in Au­todesk Fu­sion 360 and 3D-printed it him­self, round­ing it out with off-the-shelf parts from TQ RC Rac­ing. The chas­sis has a Pan­hard-style rear end with a Tamiya F104–style front sus­pen­sion, so it uti­lizes mo­tor mounts, rear axle/ drive gear, front up­rights, and front springs, all from the F104. The front shocks are 55mm pieces from 3Rac­ing. It uses an Ex­otek spur gear and a Xenon Rac­ing pin­ion gear. The rolling stock are two-piece 3D-printed rims with Proto­form VTA 26mm front and 31mm rear tires. The power sys­tem is a 21.5T mo­tor with a 2200mah Lipo bat­tery, both from Turnigy. The body is made up of mul­ti­ple parts 3D-printed out of 3D So­lutech PLA fil­a­ment that are then bolted to­gether. Brett re-cre­ated the open ducts, lou­vers, vents, and scale ex­haust pipes on each side. The wind­shield was sourced from a Lexan body and bolted into the wind­shield frame. He also added a Onkuey light kit and stickers from a Tamiya 787B kit snagged off ebay. Brett de­cided to make his de­sign open source so that any­one who wants to can print for them­selves from Pin­shape or other 3D-print­ing de­pos­i­to­ries.
