@Mike H Mottler posted:Thanks for posting your note with pix. I bought a disco ball for a similar project -- for a Christmas-decor plastic blimp that has a battery-powered spinning propeller. I've drawn several sketches of how to mount it so it would travel along a tri-oval path above my layout. Admittedly, my mechanical engineering skills are lacking, and I'm now working on my third sketch.

Never used the battery one only 120vac. The best part is that I have these running for years 24/7 spinning white/black foam board for maximum picture change so the camera could detect motion. When the start to make noice is when I Replace the motor in. On the airplane one I made something like a slip clutch for the motor to spin. Bit first then when it is stopped, the motor stops but the spinning continues for a little bit. This is to absorb the gorge of the motor to the planes and planes to motor saving the motor gears and mounts🤓
