ZTW Mantis Slim G2 Series 32-bit ESCs combine the latest advancements in speed controller technology with a compact, lightweight design specifically crafted for F3P and sailplane applications.

ZTW speed controllers are one of the most widely used and trusted speed controller brands available on the market today. They are sold under many different brand names, but we choose to purchase direct from the manufacturer without rebranding so that we can pass the savings on to you. ZTW controllers represent a new generation of brushless ESCs using advanced microprocessor technology. They are designed and manufactured with high quality components which provide exceptional reliability, low internal resistance, and a smooth, linear throttle response.

Mantis Slim G2 Features:
  • New generation high-performance 32-bit microprocessor (compared to 8-bit in generation 1 Mantis Slim ESCs) provides the following:
    • Faster throttle response
    • Smoother and more accurate startup
    • Improved throttle linearity
    • Better motor compatibility, especially high RPM motors
    • Lower heat generation
    • Higher efficiency
  • Upgraded BEC compared to generation 1 Mantis Slim Series.
  • Separate control board and power board design for better performance under heat/heavy load and less circuit interference.
  • Supports switching motor rotation.
  • Synchronous rectification significantly reduces the heat generation and increases run time.
  • Multiple protections: start-up, over-heat, low-voltage cutoff, signal loss, phase loss.
  • Programming via phone app, LCD program card, or transmitter.
  • Pre-soldered with 2.0mm bullet plugs and JST connector

Specifications:

  • Continuous current: 15A
  • Burst Current: 30A
  • Cell count: 5-12NC / 2-4s Lipo
  • Weight: 9g
  • BEC output: 5V @ 3A
  • Dimensions: 25.5x15x5.2
  • Power wires: 20AWG 60mm
  • Motor wires: 20AWG 60mm
  • Connector type: 2.0mm pre-soldered / JST battery plug

Programmable functions (default setting in bold):

  • SMR Function: OFF/ON
    • This function supports switching the motor rotation to decelerate when the airplane landing to the ground.
  • Brake Type: OFF/Soft/Mid/Hard
  • Timing: Auto/Low/Mid/High(5°/15°/25°)
  • Motor Rotation: CW/CCW
  • SR function: ON/OFF
    • The synchronous rectification function makes ESC with higher driving efficiency and more energy-saving.
  • Battery cells: Auto/2S/3S/4S/5S/6S
  • Low Voltage Cutoff Threshold: OFF/NIMH50%/NIMH60%/3.0V/3.2V/3.4V/3.6V
  • Low Voltage Cutoff Type: Reduce Power/Cut Off Power
  • BEC voltage: 5V/3A
  • Acceleration: Normal/Soft

Not sure if I should be disappointed, or if I just snagged a defective one.

Long time user of ZTW hardware here.
I was intrigued, after being unable to find the original 12 amp mantis controllers, I had discovered that they were superseded by their slim counterparts.
After hearing this, and being surprised that neither of these controllers can handle the switching load needed to spin a motor at 60k, or more... I began hunting for an alternative.

This is when I discovered that ZTW released a second gen mantis series. I was immediately eager to get my hands on one.
To my surprise, these can indeed handle motors that get uncomfortably close to the 100k RPM range... Seemingly without issue. This is likely due to the new chipset that is used on these controllers.
With that being said, the one I purchased seems to have either been defective, or otherwise flawed in some fashion. After about 5 seconds of testing on the bench, the ESC failed... and seems to have taken the motor with it.

Seems that only half of one phase has failed.. one mosfet has seemingly blown closed, and is pumping DC into the cycle, causing any motor connected to it to squeal, run poorly, and overheat.

Perhaps it was just a manufacturing defect. This stuff can happen on occasion.
Strangely, none of my other first gen ZTW stuff has failed, to date, over the course of the ~9 years that I have owned any of them.

Perhaps a word of caution. Bench test these before running them, just to ensure that you've got a solid one... Before installing it in something of importance.
