We have found that fan cooled motors tend to heat up regardless of what you do. Both our shooter 550s(100% at 10 seconds at a time) and our drive 550s(constant starting and stopping) all got really hot. I personally wouldn't reccomend fan cooled motors for a drive application unless you are thinking of using another fan to cool them.

I think that a bigger problem is your Bag motors is your application. You have many CIMs working together to speed up your robot. On the other hand your shooter ratios may not be ideal so you may be working your Bags extra hard.

We took a dead motor apart and found that the bearing was shattered
