The new 1.5mm aluminum chassis pushes the ARC A10 series touring car into a new frontier. The chassis lowers the height of all parts by 0.75mm and provides consistent flex without being affected by the air and track temperature.

Chassis slot for the motor is removed and it helps to make the flex more evenly. Compared to the  carbon fiber chassis, it is 12.5g heavier.

Installation of the 1.5mm aluminum chassis requires the use of R142032 Motor Mount and R149007 Thin Screw Set. It is also highly recommended to use R149005 A10 Tweak Stick to install the upper deck to ensure optimal flatness.

You should also remove some material from the chassis locating pins that are on the lower bulkheads and servo mount.
