Bump Steer : 3.5 on X4'23, 4.5 on X4'22 Droop : 4.4 on droop gauge (measured at bottom of shock eyelet on the arm both front and rear) Rear top deck : 2.0 cut from solid deck so i can still use the bearing option. Front weights : 2, 10g (20g total) hudy weights between servo mount and battery Need to play with raising upper arms up higher than 2mm. 3.0/2.5 for this setup this particular race day would most likely have been better.
