They saw very little usage. I saw a couple used for infeeds for shooters, a couple other folks tried to gear to do shifting because they were more powerful than the servos allowed at the time if I recall correctly.....

I was more going off of that minibots were made of FTC parts in general, although, I guess the definition of "FTC parts" has expanded quite a bit since 2011.

Not a insurmountable problem but the 5V bus current limits you regardless of the rules. As a personal thing I try not to put motor loads on a controls power bus anyway.

Isn't that closer to a gearbox modification though? Did they also ban the Turbo gear set?

Re: NeveRest 60 in FRC

Same speed and similar power to a window motor, with an encoder - yes, we've had an application most years where this would have done the trick. At least twice we've had parts which we needed to deploy outside of the frame perimeter at startup, but that were then held in place with a latch or gravity, and several internal feeders and game piece controllers for which this would be a great fit. At $28 or 20 FC points each, they're also a fairly inexpensive encoder, even if you don't use the motor. And hey, they already have power poles installed if you do!

Sent from my desk at AndyMark
I don't have test data on this motor, yet. As the one who published data on the 2011 Minibot motors (aka smoke generators), I believe that the new motor is a significant improvement; this is based on a visual inspection of an early sample motor at Andy's desk during a visit to AM a few months ago, and on review of the data furnished by the motor manufacturer. I expect the Andymark engineers will be publishing their own test results soon. We should all suspend judgement about the NeveRest 60 for a while -- AM data will go a long way toward building my understanding of its real capability, and of course a season of in-situ performance will go even further.

All that said, there is data already available on the AM site. And that data supports what Billfred said above.

I'm pretty sure I've seen some turrets driven by a 393 motor in 2012.
