Payment Policy We only accept payments via PayPal. All payments must be prepaid,Description: 4A Brushed ESC Speed Controller 1S RC plane Coreless Motor 8520 N20 N30 Electric current :4A Voltage :1S (3.7V ) Size: Features : This product is super small size, can drive all kinds of 1S 720, 820, N20, N30 motors. It's a good choice for 1S small airplane and boat. Parameters: * Voltage 3.6-6v current 4A (available 1S lithium battery) * remote control signal PWM (1000-2000) (1100-1900) run-length automatic adaptation * Low throttle unlock to prevent the high throttle motor from turning unsafely (after unlocking, in order to give a clear indication, the electric regulation will drive the motor to make sound, but in the case of easy-to-turn electric opportunity to turn two times at low speed, do not need to be nervous) * With out-of-control protection (loss of signal (equivalent to the break of the electrical signal line), motor shutdown) Plate size: 18x9.5mm, plate weight: less than 1G On Receiver Power Supply: The power supply mode is battery direct power supply, with 3A continuous current diode. But when high current is used, the voltage drop of 1S battery is very large. If the battery voltage is 3.88V and the voltage is reduced by 3.06V when the current 4A is used, the voltage can be adjusted under this voltage, but the receiver may not work. The Fuji 3-pass receiver can still work normally with the measured 7-pass space-to-Earth flight, but Leddy can't. The recommendations are as follows: 1) If you want to drive 8520 or even 1020 hollow cups with the Fuss receiver, you can use this electric adjustment. (Because there are too many brands of receivers to be fully tested, not 100% of them are guaranteed to keep your receivers supplied.) 2) If you use Leddy, consider using it in 2A-3A. Because the current is too high and the voltage drop is too high, the Leddy receiver may be disconnected. Note that the receiver is disconnected because of the large voltage drop. This adjustment is irrelevant. The 2.7V regulation can also work.
