Spedix GS40 40A BLHeli_32 2-6S 4-in-1 ESC

As one of the most relied upon brands for electronic speed controllers around, Spedix has always been know for performance and reliability.  The all new Spedix GS40 40 amp 4-in-1 esc is designed to continue the tradition of price, performance, and reliability that put the company on the map.   To achieve that goal, Spedix used the lowest RDS standard size 40V 5x6mm MOSFET with only 0.85mOhm resistance. In contrast to the 30V MOSFET used by most competitors in the market, this 40V MOSFET improved the overall accuracy and response time to throttle signals. To meet the strict requirements in competitive racing, Spedix designed a 50V power supply circuit and also clean 5V output. To improve high current workload, Spedix uses high TG 6 layered PCB even though the cost is much higher. The included heatsink doesn't add to the size of the ESC and is only covering the parts that count, reducing weight compared to a full board heatsink. On top of all these exceptional design decisions, the engin
