Re: Prototype Small Wheeled Shooter

I have found them to get warm but never as hot as our drive CIMs or anything like that. I think most of the 1:1 heat is from the bearings but I have no way to know that.

One of the reasons we are choosing to run BAG motors is so far they have taken all the heat we have thrown at them, which is mostly being stalled several times in a row from failed collector tests. We ran BB550 on our collector last year and stalled it once for 20 secs or so and smoked the motor. The BAGs are expensive but we don't have to replace it this competition season it'll be worth it.

I'm interested to see how the bearings in the VPs hold up over the course of the season. We'll have spares gearboxes on hand but hopefully won't have to use them.
