Package includes :

Sunrise Cicada 4in1 35Ax4 BLHeli_S ESC

Features :

Run on BLHeli-S firmware that is designed for superior performance in multirotors

Use hardware generated motor pwm for smooth throttle response and silent operation

All codes use damped light mode

Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling

Support features to prevent sync loss, with tuneable parameters that can make the code run well even in the most demanding situations

Support regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and Multishot (5-25us)

The input signal is automatically detected by the ESC upon power up

Also support a beacon function for finding lost aircraft, the ESC will start beeping after a given time of zero throttle
