@Joey no worries! Spear weapons are an interesting area.

@Ellis, Oh yeh the fan motors are way more torque-y. In terms of stall toque though, drill motors after the gearbox should be sufficient.
My main consideration is the weight (1.6kgs each) and size (110mm Dia, about 60mm deep) for fan motors, and that's without any sort of gearing. They'll also stall at 200a each at 24v, drill motors shouldn't get above 100a (which is the rating SSRs I have).

What reduction did you say you were running? 5:1? It seems pretty quick and can obviously lift other robots fine.
