Spedix GS40 4 in 1 BLHeli_32 ESC, 2-6s 32-bit

The GS40A-4IN1 speed controller for mini quadcopters is designed to offer the best performance and reliability in its category. To achieve the target, Spedix have used the lowest RDS standard size 5×6mm MOSFET with only 0.85mΩ resistance, making the ESC actually 40A capable in the real world. In contrast to the 30V MOSFET used by most competitors in the market, the 40V MOSFET improves the overall reliability in fast response times during throttle signal changes. To meet the strict requirements in racing competitions, they have designed the ESC with a BEC providing a clean 5V supply. To improve the high current workload, a 6-layer TG PCB is used, even though the cost is much higher, this makes the performance and reliability much better for fpv and drone racing. On top of this, the engineers have kept the dimensions compact, so no space is sacrificed in your racing quadcopter.
