The problem is that when we put the gearbox into neutral, the output shaft still has a significant amount of drag on it because there are still 2 or 3 gears engaged. Outside of making a custom gearbox (we don't have much for shop access), what could we do to make the neutral free-spinning? Thank you for the help.
you could always put an idle pulley/ sprocket on, and use a spring and a servo to engage/ disengage the drive
