Similar to the SP-1 F1 Pro chassis from Speed Passion, this version comes from Tresrey and features their signature red anodising throughout. The chassis utilizes a high quality 3mm streamlined carbon fiber lower chassis, a 2mm upper deck, and lightweight 7075 aircraft grade aluminium. Chassis stiffness can also be fine tuned using 6 chassis posts depending on track conditions. The SP-1 F1 chassis also allows different LiPo battery positions and configurations and can fit regular size 2 cells LiPo batteries or shorty 2 cell LiPo packs. The SP-1 F1 chassis represents Speed Passion’s high quality standards on and off the track as racers can put the chassis’ craftsmanship and attention to detail on display.
