The OR30 is a sensorless brushless ESC designed for outrunner motors in 1/30, 1/24, and 1/18 micro crawlers. Powered by INJORA Roverin control technology, it is built for smoother low-speed feel, more linear throttle response, app-based tuning, and flexible outrunner motor setups.
Choose the OR30 if you want your brushless crawler to feel smoother, more controllable, and easier to tune — whether you are upgrading from brushed or already running a brushless system.

Compatibility:

• Radio System: Not compatible with the stock TRX4M Ascent-18 Radio. A transmitter and receiver with a CH2 port are required.
• Transmission: Compatible with TRX4M, Ascent18 transmissions, not compatible with 370 transmission.

Which Version Should You Choose?
Both versions are the same ESC. Every OR30 includes a battery adapter cable, so either one runs 2S and 3S. Pick the version that matches your usual battery, and it plugs in directly, no adapter needed.

PH2.0 Version — best if you:

• Mostly run 2S batteries with a PH2.0 connector
• Want the cleanest, most compact wiring
• Still want to run 3S when needed (adapter included)

XT30 Version — best if you:

• Mostly run 3S batteries with an XT30 connector
• Want the best performance from 3S power
• Still want to run 2S when needed (adapter included)

Features:

• Designed for Outrunner Brushless Motors
  Built for micro crawler outrunner motor setups, giving builders a smarter ESC option for compact 1/30, 1/24, and 1/18 brushless builds.
• Smoother, More Linear Throttle Feel
  Helps deliver smoother startup, finer low-speed control, and more predictable throttle delivery from slow crawling to higher throttle input.
• App-Based Tuning with Adjustable Drag Brake
  Built-in Bluetooth allows quick parameter adjustment through the INJORA LINK app, with no extra tuning card or Bluetooth module required. Drivers can fine-tune throttle feel, drag brake, and other settings directly from the app.
• Waterproof and Dustproof Protection
  Designed for all-weather crawling, the OR30 is protected against water, mud, dust, and snow for more reliable outdoor use.
• Comprehensive ESC Protection
  Built-in protection features include low-voltage protection, overheat protection, overvoltage protection, overload and stall protection, and throttle signal loss protection to help protect the ESC, motor, and vehicle during use.
