I used the technical data from my machine's spec sheet to get the feet per minute from each function.
My motors are:
Swing-2500rpm 1/17hp 130vdc
Drag- 500rpm 1/12hp 130vdc
Hoist 417rpm 1/29hp 130vdc
They are geared down to approx scale feet per minute through the gearing. The drag is too fast so I have the max rpm turned down.Someday I want to build the gearbox for the drag correctly using all the gears exactly like the 1:1 machine.
I can also change my speed by changing the stick travel with the limits on the DX7 transmitter.
