The initial XRAY ECS Drive Shaft with 2.5mm pin equalizes the rate between your drive shaft and so the wheel. With a genuine 2-piece joint concerning the axle although the wheel, the very same extreme wheel turning angle is divided into two shallower perspectives without joint binding. Meaning at the exact same cornering rate, the internal wheel wont bind or vibrate. Drive through part is more stable, more accurate, and much more simple to push. The ECS Drive Shafts help in addition with enhanced landing after jumps. Utilising the ECS drive shafts, wheel vibrations and sound are decreased to minimal, steering is increased, stability of vehicle is increased and cornering speed and smoothness are somewhat increased as well. Important option part.
