KO Propo Member - That's why I am a vfs-1 believer for its customablility and variable frequency.
I believe the underlying principles of all modern speedos are basically the same, except the VFS has the trigger-sensitive variable frequency, which currently other speedos such as the futaba mc800c can only operate at steady 1 freq at a time.
However, I would like to know a little bit about the technology behind the modern speedo.
I understand that the escs today use pwm to control a motor's speed... That way no external resistance is required to create a voltage drop.
But what is happening (to the voltage curves) when a person pushes on the throttle on a spd control that only operates at 1 frequency?
How bout on the VFS-1? What happens to the voltage on an esc that has variable frequencies?
How does this result in the Low freq = more punch and High freq = more speed that is talked about on the KO webpages?
Finally, how does this all tie in with motor characteristics?
I know i am sailing abit away from vfs here, but if I want to be a full believer of the product, I want to understand fully, at least in theory what the vfs does to accomplish its task. Please smack me with some technical details.
I wish I had an oscilloscope... sigh.....
