The calculators specified here probably won't be available now but the article explains the principle.
I made one years ago using the gearbox of a Megger & a cheap calculator. It worked but because the gear ratio was very high (IIRC 16:1) the calc couldn't keep up so I arranged the micro switch to operate from the input & multipled the result by 16. Of course after a few flights I knew how many winds each model took without the multiplication.

How big the motor?
SAMS models have a range of lightweight winders suitable for indoor. For outdoor, I use a hand drill with the chuck removed and the shaft drilled to take a piano wire hook

For my single-channel models with rubber driven escapements (yes, really!), I use an old hand drill with a "hook" made out of piano wire. The drill has around a 3 to 1 ratio.

You Single Channel guys should use one of these devices to wind up your rubber escapements. I am not sure where mine went after I converted my Junior 60 to proportional control?
