How "bad" are motors with "bad" stickers?

And that temps gonna climb real fast!

I love the smell of burnt motors in the morning!

Last year, two of these motors were enough to lift a 130 lb robot six feet off the floor in seconds. So you should be able to easily lift 10 tetras at a time to a height sufficient to cap a goal.

You have more than enough power available, the question is "Can build a structure that can handle it and still meet weight requirements?" or "Can you build a gripper that will hold 10 tetras?"

Remember P=F*d/t

Where P=power
F=force
d=distance
t=time

Given enough time, even the weakest motor could lift anything any distance. Decide how much you want to move and how far you want to move it. Then figure out how fast you need to move it. That will tell you how much power you need.

The FPs are vastly underrated by the FIRST community at large, but those of us who have bent 1.5"x1"x1/8" aluminum C-channel with them have great respect for them.
