IS40 4IN1 MINI is an extremely reliable 20*20mm mount 6S 4IN1 ESC. Limited by the smaller size of 20*20mm ESC, Engineers have always been using 3mm mini MOSFET  used on 20*20mm ESCs.


This compromise made these ESCs vulnerable to the ever-growing demand of heat sinking capabilities and current/voltage tolerance of the FPV market. With our innovative design, by separating the control board and the power board, we successfully implemented full-size 5*6mm MOSFET onto this 20*20mm ESC.We are able to present you with a high performance mini 20*20mm ESC of extreme reliability and responsiveness.



  • Innovative double-deck design enables the implementation of full-size 5*6 MOSFET on 20*20mm mini 4IN1 ESC.
  • 40V MOSFET improves the overall reliability in fast response to throttle signals,making the 6 cell input capable in the real world
  • Silicone rings insulate standoffs, PCB, and parts.
  • The extremely small size makes mounting on smaller frames easier than ever.
