Your sawbot can be either damage-orientated (use classic sawblades or Backlash discs) or strength-orientated (best choice is WhirlWep discs but you can also use chewblade saws). Damage-orientated sawbots are extremely powerful but have vulnerable weapons, and vice versa for strength-orientated ones.

As all the saw-like components are all lighter than 50 kg, you shouldn't use very powerful motors. A Perm 132 is too much excepted for the REALLY heavy saw designs, like two heavy replica discs or many chewblades in a drumlike design.

A TWM3R is a good choice for any classic sawblade, but for heavier discs like the replica discs you'd be better off with stronger motors, especially since the disc CAN be stopped if the disc isn't perfectly circular (toothed weapon) or if the motor is really too weak for the weapon.
