DYS BLHeli 30A ESC 500Hz 2-6s (OPTO SN30)


The DYS BLHELI SN30s are a great ESC for anyone looking for a high-amp handling ESC in a small form factor.  These are perfect for the racer pushing the limits of what is possible right now.  They run BLHELI firmware and can do Oneshot with active braking (what is needed to achieve the highest performance in a mini quad)

The are OPTO escs so you will need to get a separate power source such as our micro BEC for your flight controller and other 5V electronics.
