The X4F chassis is designed for the CFF suspension arms that are mounted via pivot balls directly to the chassis.
The X4F chassis works together with the motor mount and bulkheads using alignment holes for the centering pins on each of the mounted components. Thanks to the centering pins, the assembly of structural components is hassle free, and most importantly the parts resist movement in a crash to let you finish the race without losing pace.
The narrower design of the chassis together with the perfectly symmetrical shape provide optimal flex characteristics.
