## Description

desertcart.com: INJORA MBL32 G2 Waterproof Brushless ESC & 1721 Purple Viper Outrunner Motor for 1/18 TRX4M Ascent-18 Upgrade : Toys & Games

Review: Great little motor for TRX4m cheaper than traxxas brushless - Great little brushless motor plenty of power for a Trx4m super slow crawls and plenty zippy if your going for a walk, highly recommend. Software could be a little easier/simpler to work with but with some help of YouTube you can figure it out
Review: Great crawler performance and quick response! - The ESC is great if you want to run the motor really slow in a crawler. It also responds to throttle much quicker than other ESCs I tested. It was the only one that gave good results when used in building my own servo.

## Features

- Note: Not compatible with stock 2-in-1 Receiver & ESC.
- Note: Some noise at mid-throttle is normal for the 1721 motor due to its high-speed, open-rotor design. This does not indicate a defect.
- Note: The 1721 Purple Viper is best for rigs under 700g. For heavier rigs, we recommend the 2204 Fat Viper for stronger drag brake performance.
- The INJORA MBL32 G2, based on the AM32 firmware, is meticulously tailored for Micro crawlers and is programmable.
- Smooth and linear at low speeds, powerful and aggressive at high speeds. Runs more quietly than brushed systems, producing virtually no noise.
- MBL32 G2 features a built-in BEC with adjustable output: 6V/7.4V.
- Waterproof Design for all-weather performance.
- Supports PC Programming via USB programmer card. Factory settings are optimized for INJORA 1721/2204 motors—adjustments are not recommended.
- Multiple Protections: Low-voltage, fail-safe, and rotor lock protection.
- 1721 purple viper outrunner motor, equipped with a mounting plate to install TRX4M transmission.

Awesome out of the box, but a pain to change parameters on, a programing card would be great.
