Even though I'm still in the process of building the first digital
torque meter, I can already see a couple of advantages.

First, it is a "one size fits all" -approach. The scale that I have
taken apart is a 100g/0.01g one. I plan to use 1cm torque rod to use the
gram scale as g*cm. My SO (or the national equivivalent) require motors
up to 80 g*cm, while F1M uses up to 60 g*cm, F1D up to 25, and LRS maybe
10 g*cm, for these models I'd at least two, maybe three, torque rod
meters, but a single scale-meter would take care of them all. Even in
the LRS scale I would have resolution of 1000 steps until fully wound
motor, much better than the resolution on analog scale.

Second, I feel that the possibility of logging the development of motor
torque while winding up will be help getting the max out of the motors.
