The VFS (variable frequency system) technology provides you with the ultimate control in electronic speed controllers for brushed motors.
KO PROPO has remapped the amplifier to give the most out of the esc. Standup or laydown style of brush motors will also benefit with the turning off/on the pre-programmed drag brake feature. The current ICS-USB Adapter HS (61028) and the multi setting adapter (61009) are still compatible and are required for programming changes.
Features adjustable drive frequencies (0.9-12kHz) for each of the 32 throttle steps, brake frequency, drag brake adjustment, power save feature and throttle response allow for full tuning capabilities. The VFS-1 Pro C3 comes with a 23T motor profile installed, power capacitor and Ultimate booster.

VFS-1 BMC v1.5 ROAR Spec No.40051 [Brushless ESC]
Version 1.5 of the BMC has proved itself at the ROAR Carpet Nationals with 3 TQ positions and two wins in it's first outting. Five new preset programs and now you can adjust the drag brake through the setup switch in 10% increments (OFF-50%). All specs are the same as the original 1.0 version, but you will also be able to take advantage of the Stock Motor Manager for increased speeds.
All v1.5 now include the added ROAR Spec function to comply with the NO timing class. The switch LED will flash at neutral to indicate that 0 timing has been set to the ESC. If you still want to run timing in the ESC, you can still set the timing function but the LED will not flash at neutral. This makes the ESC versatile for your application that you wish to use it in.
The VFS-1 BMC uses KO PROPO's patented VFS technology.
Five preprogrammed settings
Overheat & Current Overload protection equipped
