KO Propo should make a Program Box (or something like that) for their VFS-1BMC ESC.

Are you talking about the original VFS-1 ESC the brushed one or the VFS-1 BMC (Brushless ESC)? Normally you can upload via USB, and also on the newer radios you can adjust the ESC from the Radio as well.

The VFS-1 BMC ESC should have a Program Box.

I think that although that is common, Sanwa is trying a different approach. USB is old school, Program Box mid school, and doing it over the radio is new school.

KO Propo needs to make an upgrade for the VFS-1 BMC (in the user area).
