CNC-machined framework created from 3mm top-quality Swiss 7075 T6 aluminum, redesigned to suit both smooth and tricky composite radio containers without modification. Strategically machined in low-stress areas, then anodized rendering it since light as you're able to without impacting energy or rigidity. Non-essential item under the motor, automobile's vehicle's gas tank, and differential was indeed eliminated permitting the least expensive feasible center of gravity and optimal framework flex.
