They list the brake as proportional, and the reverse as reverse w/lockout...
Could this be our car 12s esc... If it has proportional brakes and reverse with lockout then it sounds like car programming to me...
Wonder if pdel could cast some light on this. Would car braking forces destroy the esc, as boat braking is not really much more than stopping the prop from freewheeling. Wonder what kind of programming the esc will have? The original hydea hv esc is pretty light on programming, not much more than lipo cutoff on castlelink.
