4 X Bird Dog 40A K-9 ESC Set

4 X Bird Dog 40A K-9 ESC Set
Price: $135.00

This is a complete set of 4 ESCs.  🙂

So you loved our Bird Dog 30A ESCs??  Well, you will love these even more.  We are proud to release our new K-9 ESC.

Remember these ESCs is also an OPTO – No onboard BEC.  It also has a custom Simon-K Firmware onboard for a smooth throttle response. 

These ESCs have a larger heat sink than our 30A and are also thinnner, and with all N-FETs onboard.

The K-9 ESCs will not shut down when your battery gets low, so you MUST monitor your battery power.  We have included 3.5mm connectors that are soldered directly to the ESC for nice clean installation on your multi.


  • Battery 3S, 4S, 5S and 6S
  • 40A constant – 60A Burst
  • All N-FET
  • Custom SimonK firmware.
