Without the shoulder bolt, the rotor is not fully constrained and may be damaged. The 1/4″ x 1.5″ shoulder bolt is great for bots with 2x 0.25″ uprights. When designing the blade, ensure the tooth portion lines up with the 2 screws at the top. This provides the most optimal loading scenario with maximum strength. Three-tooth weapon designs are not recommended. Order your high-performance hub motors today and take your combat robot to the next level of power and reliability!
