Rebuilding after sumo loss. Stuck on motor choice.
Brushed N20 12V 300rpm: torque ~0.5 kg-cm, life ~50hrs comp. Cheap, replaceable.
Coreless 1230 12V similar rpm: torque ~0.8 kg-cm, life ~30hrs. 5x spare cost.
For 90s pushes coreless wins on paper. Anyone run coreless full season to nationals? Worth pain?
