Someone from the Sky Galleon of Mars discussion yahoo group is starting a Victorian Science Fiction airship and is trying to get info on motorizing the counter screw propellers. With possibly making the engine mounts move 180 degrees as well. Has anyone done somthing similar or know of any links to find more info to help?

Thank you.

Old dental drills.. (taken apart and machined to fit brass tubing)
Disposable dental drills...
Electric tooth brushes occillate(go back and forth) but is it really going to fly?

Graupner RC boats sells a small Schottel Z drive, but it runs about 70-80 bucks. I geared mine to turn 270 degrees. Also, the Shaft length is limited.
See the bottom of this page...

Finding good 45Â° beveled gears can be tough, and expensive.

Wild suggestion: those teeny motors supposedly used in pagers to make them vibrate. The smallest ones fit into tiny spaces, or simply mount the entire mota on the top of a T mount sticking out of the side of the hull.

I believe I've seen those tiny cellphone/pager motors for sale in the Jameco catalog. I'm sure that other electrical component vendors would have them.

They can be found online (Found a great link with tons of online suppliers: here), in old Nokia phones (their defunct 5100/5200 series had the vibracall motor placed inside the battery pack â€“ the kind which was the full backside of the phone â€“ so after the batteries are gone for good, the little motor's still there), in micro-sized RC toy cars (the ones about the size of a HotWheels car â€“ same thing: the batteries will eventually go poof, so the car's there to be picked clean).

Just the motors!!

oooo... beautiful... probably weak as heck, but plenty capable of moving small bits of plastic, i'm sure.

thanks.
