The Spedix GS45A-4IN1 ESC was designed to have the highest performance and reliability possible!
To achieve this goal, Spedix-RC used the lowest RDS standard size 5x6mm MOSFET with only 0.85mOhm resistance, making the ESC 40A capable in real world applications. While most competitors on the market utilize the 30V MOSFET, Spedix used the 40V MOSFET, which improves the reliability in fast response to throttle signals. To meet the strict requirements in racing environments, Spedix designed 50V power supply circuit and 5V clean power output. To improve high current workload, they used high TG PCB of 6 layers even though the cost is higher. With all of these features, the overall size is still the same as a standard 36mm flight controller board. Try the Spedix GS45A 4 in 1 ESC in your quad today!
