Maintaining perfect control of mecanums using encoders?

Not to beat a dead horse, but are you saying that you observed ^this^ with a Talon as well as with the 884?

Team 1718 test, unloaded output voltage vs PWM command for 884 and Talon.

If you still have the actual data, would you please post it?

BTW, how did you use the GoPro to measure speed? At 5000/4.67 RPM, 1/120 of a second is 1/7 of a rev. Did you put a circular protractor on the output shaft?
