No more garbage motors in the interest of "variety."

Building on this, FIRST seemed to attempt the "pick a motor that suits you" system this year with the Banebots motors. It's a good idea, but the quality of some of the motors left much to be desired.

The CIMs have proven to be as close to indestructible one could hope for in a motor for FRC. With the way drivetrains have progressed you pretty much have to use them in the DT to stay competitive. Even 1 additional CIM goes a long long way.

Your point is well stated, but I think the wording might not quite be accurate.
I believe a better choice might be:

Re: Banebots RS-775 Case Short

I'd support unlimited CIMs if Andy Baker promised not to sell a 4-CIM gearbox except through 'custom' orders that wouldn't be FIRST-legal anyways. :shudder:

This thread is making me a bit nervous. Our primary lift motor (the one that's bagged) is the FP-673 through an AM Planetary + CIMple box, yet our backup motors (the practice bot + spares) are all RS-775's through BB's gearbox and a CIMple box. Unless we tip, we've found it's not possible to stall/burn out our FP lift motor under normal operations (acme rod = higher torque, less speed, natural braking) so I don't forsee this becoming an issue. Yet perhaps we'll get a spare FP motor tomorrow.

I hate to say it, but stalling/not stalling the motor has nothing to do with it.

I meant that for the FP-673 motor that's currently installed on the bagged production bot. Updated it to clarify.

Re: Banebots RS-775 Case Short

Do chassis-faulted motors have different output power? Has anyone stuck them on a dyno?
