crown gear: 70 tooth 107mm dia
pinion gear: 12 tooth 20mm dia
12v motor w/264:1 planetary gearhead running 40rpm on 3s lipo
I manipulate the speed with dual rates radio programming, I have a slow speed for up to 90 degree swing with precise control for minute movement & a higher speed for 180 - 270 swinging - fast digging.
I have a pic, but photo host not seemingly working atm (not for me anyway), maybe it will show tomorrow...
