INJORA CNC Aluminum 24:1 Transmission for 1/18 Redcat Ascent-18 – Upgrade

Upgrade your 1/18 Redcat Ascent-18 with INJORA's CNC Aluminum 24:1 Transmission. This compact, precision‑engineered unit slots into several Ascent-18 configurations, delivering a robust platform for off‑road crawls and trail runs. The housing is machined from high‑grade aluminum, and the gear train is tuned to maintain familiar stock performance while offering new control options. Built with reliability in mind, the assembly emphasizes durability and repeatable engagement under load, so you can focus on line choice and throttle control without worrying about gear misalignment.

Compatibility and installation at a glance

• Compatible with 1/18 Redcat Ascent-18 Brushed, 1/18 Redcat Ascent-18 Brushless, 1/18 Redcat Ascent-18 Scout II Brushed, and 1/18 Redcat Ascent-18 Scout II Brushless; not compatible with Apex.
• Note: Not compatible with the stock Redcat Ascent-18 motor; works with INJORA TRX4M, Ascent18 180 motors, and INJORA TRX4M 1721 Purple Viper brushless motor.
• High-strength neodymium magnets for durable, consistent magnetism and reliable response.
• Pre-installed pinion and wiring reduce setup time and simplify installation with Redcat Ascent-18.

Build and gearing

• CNC aluminum housing delivers strong, precise alignment and long-term rigidity in rugged crawl environments.
• 13:1 gear ratio maintains stock speed for familiar performance in standard conditions.
• 24:1 underdrive gears reduce wheel speed by about 45.83% to improve throttle control and obstacle negotiation.

Real-world benefits and use cases

In practical crawling, this transmission can contribute to steadier climbs and smoother pacing across uneven terrain. The underdrive option helps with throttle modulation on steeper sections and technical lines. The design prioritizes durability and repeatability, with an integrated approach that minimizes loose parts and simplifies field maintenance.

Quality and ecosystem

The CNC aluminum housing provides a robust platform with reduced flex under load, while the neodymium magnets support reliable engagement. If you already run INJORA TRX4M or Ascent18 motors, this unit integrates into your existing setup with fewer compatibility concerns and straightforward installation.
