The XB4 framework is revised to place fat further ahead, with part guard mounting functions for symmetrical flex, updated fan owner mounting roles and many battery place alternatives to modify the weight stability. The framework features an even more ahead biased design. Slipper/center, engine and battery power was in fact relocated somewhat forward to improve security. The medial side guard mounting holes are symmetrical for equal left-to-right flex characteristics. The chassis features holes for a fan mount and many battery power post jobs to change the packââ¬â¢s location and adjust the F/R fat stability. CNC-machined from top-notch Swiss 2mm 7075 T6 aluminum, the chassis is strategically machined in low-stress areas to make it since light as you can without impacting energy or rigidity; also it's moreover black-coated for increased lifespan.
