About this part

This is the Hobbywing EZRun MAX10 G2 140 Amp Sensored Brushless Waterproof ESC/3665SD Motor Combo. Using IP67 waterproofing and featuring a smart sensored brushless system this versatile combo is an excellent choice for 1/10th 4X4 Trucks and Monster Trucks.    

Features:

  • The EzRun Max10 G2 ESC features an improved waterproof sensored cable interface and an upgraded sensored mode to achieve a great sense of control feel and perfectly matches the EzRun 3665 SD G3 motors.
  • Supports Turbo timing adjustment of up to 32 degrees, and in combination with the EzRun 3665 G3, the maximum speed is 25% more with greater effect.
  • The smart start-stop technology is introduced to the Max10 G2 ESC. The frameless fan will not be enabled to reduced noise and saving power. The fan will only work when the temperature rises to a certain level.
  • Compared with the previous generation of the MAX10 ESC, the total capacitance of the capacitor is increased by 74% and is overheating protected. The functions improve the power delivery from the battery to the ESC to avoid it from overloading and causing capacitors to explode.
  • Smart freewheeling technology enables the MAX10 G2 to have higher drive efficiency than the previous generation, resulting in lower operating temperatures and a minimum temperature of approximately 25°C lower than the previous generation.
  • After connecting the ESC with the OTA Wireless module, you can view the data (throttle amount, voltage, current, temperature, speed and etc) in real time through the mobile app to know the running status; The history of the running status can also be viewed by data logging.

works well when it worked. mine only lasted about 6 months! The motor is still good though but the ESC no longer functions. It started just randomly shutting down when landing off a jump. I did not abuse it or run it on my SCT with over gearing. it was in a tekno sct.

Nice upgrade for my rustler…the top end on 3s a little much honestly unless your dragging…very smooth throttle response and super easy to install! I was only bummed that the combo went on sale a week after I purchased mines…hopefully AMAIN is nice enough to give me some store credit because I took time out my day to write a review which might help them sell more combos… if they actually read these reviews?!? AMAIN hook me up!???

What reviewers say

Reviews are mostly positive, with many buyers praising smooth throttle response, strong acceleration, easy installation and cool running in a range of 1/10 vehicles including Rustler, SCT, Slash, Hoonitruck and Senton. Several reviewers note the combo is powerful, with the top end on 3S described as very strong. Two reviews report failures: one owner reported the ESC shutting down after about six months, and another reported a solid red error light and unresponsive unit after about 20 minutes on 3S. Both negative reviewers describe warranty difficulty, with one saying the retailer could only refer them to the manufacturer. Reviews do not clearly show how common these failures are.

  • + Smooth throttle response
  • + Strong acceleration and top speed
  • + Easy installation
  • + Runs cool
  • − ESC failures reported
  • − Solid red error light and unresponsive unit
  • − Warranty process frustrating for one buyer
  • − Very aggressive top end on 3S
