Spedix GS40F 4in1 mini esc 20x20 6S F3


GS40F 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.  By combining reliable hardware with the fastest GD32F3 MCU in the market,

We are able to present you with a high performance mini 20*20mm ESC of extreme reliability and responsiveness.


1.Innovative double deck design enables the implementation of full-size 5*6 MOSFET on 20*20mm mini 4IN1 ESC.

2. 40V MOSFET improves the overall reliability in fast response to throttle signals,making the 6 cell input capable in the real world

3. GD32F3 MCU provides highest responsiveness in the market.

4.Extremely small size makes mounting on smaller frames easier than ever.
