Hobby King HKing 10a Brushless ESC

Lovely spring weather means I am antsy to build and fly again. I am planning on using this Hobby King HKing 10a brushless ESC in a 230mm size acro quad. Not sure if it will be able to endure SunnySky 2204 2300kv with 3s lipo but I like the physical size…so I will give it a try anyways.


Anyways, the dimensions on Hobby King is incorrect (23mm x 18mm). Here are the actual values as measured with the digital caliper. The bare ESC as pictured weighs 2.59g.

It arrived with 20guage silicone wires for the main power. And 22gauge silicone wires for the motor leads.

Missing from the photo is the electrolytic capacitor (100uf 16v). I took it off so I can use a tantalum SMD capacitor with the same values. It’s much smaller physically. Hopefully it works out. :)

What I like about this ESC is the fact that it’s BLHeli compatible. Plus, it uses all N-channel MOSFET. And it was reasonably inexpensive at $5.78. Here’s an inexpensive BLHeli programmer, and another another. You will need one of these for flashing the firmware or updating the parameters of the ESC using the BLHeli Suite software. Unless you already have an official SilLabs Toolstick. Then you can follow this guide for modding it for the same function.
