DYS 20A BLHeli ESC BL20A OPTO 2-4S for FPV Racing Drones

Only 7.6g with wires, DYS has newly released a mini ESC SN20A at a very low cost , yet able to run BLHeli firmware and have OneShot/damping light enabled. 

Note: This ESC does not include a BEC.

Features

• Specially designed for multicopters, super fast throttle response.
• Auto-adaptation throttle, outstanding motor compatibility. 
• Twisted-pair cable for throttle signal, effectively to reduce the signal cross-talk when transmitting in the copper wire, and make the plane more stable.
• The refresh rate of throttle signal up to 500HZ, compatible with most flight controllers on the market.  
• Use the new technique with ultra-low internal resistance MOSFET, with N channel pipe drive, strong current resistance ability.
• miniaturization design, with high performance C-DC built-on the board，minimize the weight to 2g only.
• Thicken the PCB copper plate, low heat for small aircraft.
