3) How does the "3 speed/Cruise control" work? Is this a 3-position switch that just sets the motor to "cruise" at a fixed, unadjustable speed? The picture is a bit confusing because it looks like it has a switch for lights and horn.
1) Yes. As a regular product. We have a few 1680W motors left, and cobble together one or three if a customer really wants one.
3) Yes hold throttle at a fixed speed. The 3-position switch is for 80% , 100%, 120% speed, you can only set the 120% with load, the 80% and 100% can set with no load.
The horn is cruise control (yeah I know), when you turn the throttle and you press the horn the motor RPM will fix at that point, when you press again it will cancel the cruise control.
