ROSCO

I burned out two of these motors in a high-torque situation (my Great Ball Contraption module prototype) which I posted about here and here.

I don’t like them for their friction, their louder sound, and that they “feel” cheaper than the originals (weight, mostly).

What a relief to know I’m not jinxed after all.

And their high mortality rate.

I hope the proper person at TLC is looking into it.
