The Spedix GS40A-4IN1 is designed to be the best performance and reliability in the same product category.

To achieve the target, we use the lowest RDS standard size 5x6mm MOSFET with only 0.85mOhm resistance, making the ESC 40A capable in the real world. In contrast to the 30V MOSFET used by most competitors in the market, this 40V MOSFET improves the overall reliability in fast response to throttle signals. To meet the strict requirements in racing competition, we designed 50V power supply circuit and 5V clean output. To improve high current workload, we use high TG PCB of 6 layers even though the cost is much higher. On top of all these excellence in product designs, our engineers managed to control the dimensions to be the same as a standard 36mm flight controller board, without sacrificing the precious space in a quad. However, high performance is inevitably related to high costs in parts.
