With three distinct control modes and compatibility with various motor types, it offers unparalleled versatility and precision. Built with durable materials and a robust design, this ESC ensures reliable performance across a voltage range of 6-15V. ## Description Specifications:Adapted voltage: 6v-15v (Do not use high voltage, 5 / 6S may burn in seconds)Can use 795 775 540 550 380 390 high current motorCurrent: single forward 40A, reverse 20ABoard size: 54x48mm Weight :55g (including wire, heat sink)With 16AWG silicone motor wire, 18cm in lengthAdopts double copper thicknessHow to identify the forward and reverse direction:1. The throttle channel of the receiver is changed to the steering gear. When pushing the oil, the steering gear rotates counterclockwise when viewed from top to bottom.2. Also use our shop's PWM tester to plug in the receiver for testing, and the increase in the fuel value is positive)The midpoint of the remote controller is fixed at PWM 1500us (+50 -50), and the run is automatically adjusted from 900-1100 and 1900-2100.Start with the midpoint (one beep at power-on, and two beeps at midpoint 1500, ESC will start)With out-of-control protection (lost signal (in the accident, the signal line was disconnected)), for safety and motor protection, you need to return the throttle to the center and unlock againPower-down protection:power supply voltage is lower than 4V, ESC restart protection (such as: high current discharge, poor performance battery voltage drop is too large, ESC protection, motor stops after protection, and battery voltage recovers after motor stops Back to the midpoint, you hear the motor unlock again)bec output 5v max 3A to meet your needs for receiving and steering gear power supplyOverheating protection (overheating 90 degrees, the ESC stops output, and recovers after cooling down)For use in a closed environment, you can retrofit and install heat sinks, or seal the entire board in thermally conductive silicone grease, which is waterproof and dissipative.Key points of mixed control debugging:First make sure the forward and backward motors are in the same direction. (If a motor is turning incorrectly, exchange the +-stage wires behind the motor)Then adjust the direction, if it is not as expected, the remote control may be reversed, set it backThe dual-mix ESC has the following modes:1. Mixed control mode (both throttle / steering mode): 2 or 3 channels (2 channels are recommended because 2 channels automatically return to center) to control the throttle, 1 channel (or 4 channels) to control speed difference steering, throttle ratio 100%, steering ratio 100%, steering priority. Suitable for: tank (in this mode, gun control can play tanks), 4-wheel drive trolley (apm can be installed)2. Two-way independent: it is equivalent to two independent ESCs (if you want to simulate a real tank, the white three wires on the input end are connected to the receiver throttle (3 channels), and the yellow single wire is connected to the receiver 2 channels; but in fact Henglong ’s Tank is also Mixed control mode, because better operation)3. Two-way synchronization: In mixed control mode, do not connect a single yellow wire, so that the two-way motor output is consistent.Please Note:1. The left and right motor wires marked in the picture (easy to distinguish), the motor must not be confused, otherwise the ESC may burn in seconds2. Overheating protection takes effect only when both circuits are used. Otherwise, it is difficult to take effect if only the single circuit is used to regulate the uneven heating and cooling.3. Motor +-In addition to the C104 anti-interference capacitor, other capacitors cannot be connected (for example: 2uf or more capacitors)4. Some ESC motors with a current less than 2A cannot use this ESC, because small-winding motors with dense windings will interfere with the potential after the motor rotates, and the throttle will stop at more than 90%. (Please select 2A or 5A ESC for geared motors with current less than 2A)Package list:1*40A Brushed ESC Review: Was testing this ESC without load to the motors, only powering the RC receiver. Unit got extremely hot and melted the plastic wrap. The 2 chips on the end got so hot they came unsoldered. Was using a 11.1v LiPo. I was just glad it happened on my desk and I caught it, otherwise my RC could have been toast. Review: Have a toy RC with two small brushed motors (180 size?) so should have been no issue at 2S. However, on acceleration it would cutout and reset my dumborc receiver which turns off the lights. It would come back up only to do the same thing over again. Switched to the Hobbywing WP880 dual brush motor esc and works as expected. Too bad as it seemed well made and is about 30% cheaper then the Hobbywing. Returned this ESC. I only tried the one so maybe you'll have better luck with it. ## Features - Readytosky 40A x 2 Mixed Control Brushed ESC 2-4S 6-15V is suitable for RC Tank Speed Difference RC Boat. - It can be used for 795 775 540 550 380 390 high current motor. - This ESC has three modes: ①Mixed control mode: It can make the speed of two connected motors different. Differential steering! ②Two way independent mode: Realize the speed control of two motors respectively! One motor can run, one motor can not run! More simulation!③Two way synchronous mode: The motor rotates at the same time, and the speed is the same as that of the ordinary electric regulator! - Adapted voltage: 6v-15v (Do not use high voltage, 5 / 6S may burn in seconds). Adopt double copper thickness, high quality. - With 16AWG silicone motor wire, 18cm in length. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CPDXWJJ2 | | Assembly Required | No | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 2.8 2.8 out of 5 stars (13) | | Date First Available | 15 July 2024 | | Manufacturer recommended age | 18 months - 3 years | | Manufacturer reference | 40Ax2 | | Material Type(s) | Plastic | | Product Dimensions | 11.94 x 8.64 x 2.29 cm; 75 g | ## Images ![40A Bidirectional Brushed ESC 2-4S RC 40A x 2 Mixed Control ESC 6-15V Dual Way Electric Speed Controller for RC Tank Speed Difference Boat - Image 1](https://m.media-amazon.com/images/I/71gOT0O3kaL.jpg) ## Customer Reviews ### ⭐ Review *by R***M on 15 April 2024* Was testing this ESC without load to the motors, only powering the RC receiver. Unit got extremely hot and melted the plastic wrap. The 2 chips on the end got so hot they came unsoldered. Was using a 11.1v LiPo. I was just glad it happened on my desk and I caught it, otherwise my RC could have been toast. ### ⭐ Review *by A***R on 27 January 2024* Have a toy RC with two small brushed motors (180 size?) so should have been no issue at 2S. However, on acceleration it would cutout and reset my dumborc receiver which turns off the lights. It would come back up only to do the same thing over again. Switched to the Hobbywing WP880 dual brush motor esc and works as expected. Too bad as it seemed well made and is about 30% cheaper then the Hobbywing. Returned this ESC. I only tried the one so maybe you'll have better luck with it. ### ⭐ Review *by R***B on 31 May 2025* Finally got to test this esc and it sucks if I'm honest. The tank goes left and right with only the right track working and goes forward just fine but going backwards only one track spins Also the esc is getting very hot, smells like burning and I'm only using it on 3s 11.1v and 390 motors. Tried it on 550 motors too, same results as before I'm having to revert back to using two escs and a stick style transmitter. Because I do not want to keep buying parts for my projects I thought this would have been great for me to use a wheel transmitter on but in fact it is utterly useless I would have sent a video as photos do not give it justice but I have already removed it all from my tank --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/647451284-40a-bidirectional-brushed-esc-2-4s-rc-40a-x-2](https://www.desertcart.vn/products/647451284-40a-bidirectional-brushed-esc-2-4s-rc-40a-x-2) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
