Although, to be honest you will probably never ever ever see anything in FIRST that requires that sort of reduction to do something. Unless next year's game is pick up an elephant and hang your robot on the bar carrying the elephant...which WOULD be pretty sweet to see aside from animal rights issues...

Also consider that every mesh you make decreases efficiency by a few percent.

Just things to keep in mind. Keep up the good work.

the large gear reduction is for the speed that the arm gos up

if it has that much strength than i need # 35 chain instead of # 25
