TheRacerstar RS30A V2 is the next generation of speed controllers based on BLHeli-S firmware, providing very smooth and stable operation of your motors.
These regulators are a rebranding of Sunrise Model's popular Cicada regulators and all specifications are identical and compatible.
Features and advantages of BLHeli-S firmware based regulators
Dshot600 support without modifications or soldering capacitors (latest BLHeli-S firmware required).
Excellent circuit board design, high quality manufacturing and original components.
BusyBee2 8 bit chip (EFM8BB21F16) operating at 48MHZ.
BLHeli_S firmware is a more improved code based on the regular BLHeli. It is specifically designed to work with hardware PWM.
BLHeli_S speed controllers work on the basis of hardware PWM with 36KHZ update rate, realizes very smooth and quiet control of motorless motors, which makes their operation very soft as if on silk.
BLHeli_S have as good motor synchronization as the original BLHeli, and sometimes even better.
In BLHeli_S firmware active braking (damped light) is always enabled by default.
Improved resolution of throttle control. You now have 2048 different throttle level steps, instead of 512 as before.
Supports high speed engines (up to 500k rpm).
Supports 1-2ms signal pulse width, for Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and for Multishot (5-25us). Mode of operation is selected automatically by the flight controller.
BLHeli_S are flashed and customized as easily and quickly as regular BLHeli.
