Nice one.
I made a crude version with the same size motor and the gear box from one of those tiny 2 inch long r/c cars.obviously I didn’t have a feedback pot so would run continually in both directions,I relied on mechanical stops.
Served me well on a small project.
Would also be interested in more details of this little winch you have made.
the original servo LS-3.0 has 200gcm, according to WES.
Because of the gear ratio 64/12, the force may increase proportionally but not measured yet.
I will be happy, anyhow, to get some 400gcm, frictions permitting…
