The Sunrise Cicada BB2 ESCs were specifically designed and built for racing copter use! The perfect hardware design, high quality manufacturing and top brand components ensure smooth and silky control of your drone at all times! These ESCs were created for the most demanding of applications, but even if you are not a hardcore racer you can still benefit A LOT from the performance improvement they bring, compared to other brands! The Cicadas come pre-flased with the most advanced racing copter firmware available at the moment - BLHeli_S!
MCU: busybee2, 50MHZ, generated with hardware PWM
BLHeli_S is an improved version of the base BLHeli code
Delivers a throttle response that is Smooth as Silk, and the main factor contributing to this, is that it uses hardware to generate motor PWM
Sync loss protection feature. Smooth start up.
Damped light / synchronous rectification / active freewheeling
Has motor PWM that is Synchronous to the MCU master clock, as it is generated by hardware. This makes the motor Silent
Has very Small throttle Steps. The resolution varies between hardware configurations (MCU clock speed and driver type), and is between a nominal 512 steps and 2048 steps
Supports very high motor Speeds. support 500k erpm. BB2 is set to 500k eRPM (F39x around 360K)
Supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42, Multishot and the most recent Dshot. Autodetected when the ESC sees an input signal
Last and by no means least, is Simplicity. If you have a regular setup, just install and go fly (calibrate if your throttle range does not match BLHeli_S default). Or if you need to configure or update, just do so with the Simplicity offered by connecting to your ESCs through the FlightController, using BLHeliSuite and a USB cable.
