Can you reverse mini Cim while free spinning?

[team-4480]

Hi,

We have an intake that likes to throw boulders back to far when trying to suck the boulder in. We are currently contemplating different solutions but we were curious on whether we could reverse our Mini Cim to brake the intake wheels? There is hardly any friction on our intake wheels so once we start the motor up, it takes forever to come to a stop.

I know brushless motors can switch directions when spinning without issue but I don't know about brushed mini Cim motors. We definitely do not want to wreck our mini Cims! Thanks a bunch in advance!
