It looks good in 1/10 I'm not sure if I can get everything small enough to look right in 1/16.
I might have to just deal with seeing one cylinder rotating....
But thank you for showing the exploded view it helps a lot...
Yup, the lead shaft is not exposed... so far this has been the smallest gearmotor i could find which works great in 10th scale... not sure if there is another one smaller than this.

I found some 10mm motors with planetary gearboxes that I will be using to extend the stabilizers on my Manitou 2150, I think they are 300rpm. (There are listings similar to the gearboxes I got on Ebay now, just look for 10mm gearbox.) Using an M3 threaded rod as the screw they would move at about 2.5mm/second. The stabilizers have about a 70-80mm travel so I figure it'll take about 20-30 seconds to extend/retract the stabilizers. It works in the 3D model anyway - real-life might be another story.

I originally planned on driving the motor with a 10A ESC, but that would use 8 channels just for the stabilizers. I'm currently looking into auto-leveling using an Arduino and a gyro chip. I had planned on the Arduino running the lights anyway so I might as well make it earn it's keep. But that's a whole 'nuther rabbit hole.
