    • Please do not use Analog Servo for SHR mode or SSR mode. If analog servo is used for SHR mode or SSR mode, the servo will be broken and will not work. Digital servo (SRG series, Digital ERS series, SDX series) can be used both for NOR mode and SHR mode.
    • SSR mode can be used only by SRG & PGS series servo.
    • In SHR or SSR mode, BL-FORCE, BL-SPORT, F3300, SBL-02 and SBL-03CR do not work. Please use NOR mode for the above ESC.
