Because of that and a small drum the braking was good enough. I don't know that with the gear reduction needed for a CIM or Mini CIM to still have some speed if it would work good enough. The 775 was definitely warm at the end of a 5min or so "match". Of course the 775 is a fan cooled motor.

You can find our videos at www.teamredacted.org. From there you can find a link to the Ri3D website where you can find videos from all of those who participated in Ri3D this season.

A mechanical brake would certainly be preferred and if we found the drop rate to be too fast we certainly would have looked at implementing one.
Awesome. Thanks for the tips and the links. I've definitely been watching all the Ri3D videos and am no stranger to your team's bot. We've gotten some great insight already from your build. Seems like the best bet would be to just build a prototype of the system and see how much load it can hold. The team's come up with some good ideas for mechanical braking if it's necessary.

We're looking at using our remaining 2 CIMs for the elevator system which should give us a pretty powerful lift. Hoping to get it prototyped out tomorrow!
