Wanted: Gear Box with Low Horsepower and High Gear Ratio

You need to define 'small' and 'incredibly small'
this sort of gearbox comes in high ratios.
Many manufacturers do similar designs.

Or is this too small?
One man's 'small' is another man's 'Big'

These links are great!, the 1:30 ratio and size are exactly what im looking for with such low horsepower. Although, I made have made a mistake. I am looking for vendors in New England, as in the North Eastern United States.

Try a search for 'oviod gearbox' I think that's the term for that sort of gearbox.

Or Worms (if it is at 90 degress transmission).

Planetary gear boxes maje be good for 180 deg transmission (either single or double)

using globalspec search engine you may find your needs

Have you checked with your nearest electronic surplus dealer? They have stuff fitting that description most of the time in ours... mostly in the $3-10$ range, some higher.

Sounds like your local hobby shop might do the trick (model trains, cars, planes, helicopters). Otherwise RS electronics has a fairly wide range.
