4Pcs 20A ESC Brushless Electronic Speed Controller DSHOT BLHeli_S 2-4S Lipo for FPV QAV Drone Multirotor Quadcopter

I went a cheaper route and was so frustrated I finally broke down ordered this 4 pack. Wired it up and tested in my 150g combat robot project and powered it up and set the parameters. Works great! And seems like it makes alot of power.

Got these for my 1-pound plastic ant weapon motors... I run them hot and hard and break them, but these seem as sturdy as any others I have used. I bet they would do just fine for drone applications if they can handle the abuses I dish out.

works great

ESCs are rated at 20 amps, but only comes with 20AWG leads (not sufficient). Also leads are very short. Was able to successfully flash upgrad Bluejay firmware, but did not actually test. Because, I managed to recover my faulty original ESC with an online process using Arduino board, and thus didn't need replacement part. I have confidence that they would work, and would have replaces wires with wires from old part. Additional note: parts arrived with Blheli_s version 16.7.

Replacing 5 yr old technology with modern...bug difference... amazing product.

There is no battery-eliminator cable and you cannot power your board from these.

Good
