DYS BL30A BLHeli Multirotor 2-6S OPTO 30A Mini ESC

The new DYS BLHeli series speed controllers are quickly becoming the most popular ESCs amongst drone racing enthusiasts and with good reason. They are ultra small, very light and arrive flashed with the best multirotor firmware out there, namely BLHeli. Being specifically designed for multirotor use, they are tuned to deliver an ultra fast throttle response, which helps to improve stability and give you that much sough-after locked-in feeling!

For those than don’t know, BLHeli is a next generation firmware which looks set to take over from the dominance of SimonK firmware. BLHeli offers great new features like OneShot125* and Damping Light. OneShot125, simply put is a feature that lets your flight controller communicate with your ESCs much faster; the result being your multirotor can respond much quicker to commands. On the other hand Damping Light is a sort of active breaking. With normal ESCs when you reduce the throttle, the motor will only be slowed down passively by the drag of the props. With Damping Light enabled, the ESC will act like an electronic brake to actively reduce the motor speed. Again, this feature makes for a much more responsive and stable multirotor. While OneShot125 and Damping Light are the killer features of BLHeli, there are other benfits. For example, you can configure the ESCs to sound a beacon if they sit idle for 10minutes, which might just help you find your racing quad if you crash it in a field of long grass. The ESCs can be flashed with the latest version of BLHeli or Simonk using the DYS USB Linker.

This particular 30amp ESC from the range is perfect for 450-680 sized quad and hexacopters. It supports 2-6S LiPo batteries, weighs a mere 14.5g and only measures 45x16.6x5.5mm. Its miniature design is all thanks to new ultra-low resistance MOSFETs that can withstand high current and also a thick PCB for better heat dissipation.

Finally, the ESC is of the OPTO type (no BEC), which helps to eliminate radio interference between the motor and receiver; a problem that can be encountered with BEC type ESCs.

Features:

• Designed specifically for multirotors
• Tiny form factor and low weight
• Preloaded with BLHeli, OneShot125 & Dampened Light (active braking) supported
• Fast throttle response – high 500Hz maximum refresh rate compatible with all flight controllers
• Twisted signal cable reducing the crosstalk during signal transfer
• Feature all new ultra-low resistance MOSFETs for superior current handling
• Thick PCB for better heat dissipation
• High performance capacitor filter

NOTE: These ESCs have no BEC, they are OPTO. You will need a 5V BEC to power your flight controller/receiver.​

*Your flight controller must support OneShot to take advantage of this feature.
