Re: Are motor speeds proportional to PWM value?
There's no such thing as stupid questions, even from a software person. 
I know that the Victors were quite non-linear. They had a significant "deadband" near the mid-point (zero-velocity). Motor speed increased approximately linearly over a small range PWM values then would approach max speed asymptotically. The characteristics varied significantly from Victor to Victor as well.
You can measure motor speed vs Jaguar input with an encoder pretty easily. It would be good to do this free-running and with a mechanical load on the motor as well.
