You can mate with a CIM and get a ton of power out of a reliable box.
We actually use the said gear box for our aerial assist bot to arm a catapult but we have to use a one way bearing and clutch to arm and fire it. For an elevator we want to be able to move up and down at will. However if we only aim for 3 totes and use 2 sims we may be able to get away without a braking system.
