Mace's flail

Flails are a loose hanging type of rotating weapon.


  • A flail is a spinning weapon that dangles loosely, usually by a chain. When it gets up to speed, it "flails" around, hence the name. Flails were sometimes used in conjunction with Full-body spinners, their flexible designs helped prevent backlash to the robot's shell.

Advantages and Disadvantages


  • The flailing motion of the blades increases the amount of kinetic energy they carry. This allows them to cause more damage than an equivalent rigid weapon.
  • Flails absorb shocks better than rigid blades.


  • Flails are prone to breakage, which could leave the robot spinning wildly off-balance. Mauler was infamous for flipping itself due to stability issues.
  • A dangling flail can often restrict a robot's ability to self right.
