Designed for multirotor/quad racing applications, the MR-20A PRO ESC is a high-speed and high-efficiency speed controller.
Its high speed means not only a high fidelity driving signal from high side N-MOS fets but also a high fidelity, high voltage driving signal for low side N-MOS fets. This makes for a more efficient ESC and one much better suited to aggressive FPV racing and flying.
The MR-20A PRO ESC is supplied without wiring or heat shrink to allow direct integration on your multirotor with minimum additional weight.
• Supports OneShot125
• Supports 3D mode
• Supports BLHeli firmware
Built in BEC : No this is an OPTO design
Working current: 20A (Max 25A/5S)
Working voltage: 7.4V~14.8V (2S~4S)
Dimensions: 23 x 13.5 x 3.0mm (not including cables)
Weight: 1.3g (not including cables)
My new favorite 20A ESC. Small lightweight and works like a charm. With a cleanflight FC the BLHeli configuration and firmware upgrade is just a few clicks, without any soldering.
Just connect the FC to the PC and start the BLHeliSuite...
Btw its "MR-20A" and not "MR-20A PRO". According to the overskyrc.com the PRO version is built with an 48MHz F396 microcontrollers not the F330.
