Frequently Asked Questions
Which motors are compatible with this ESC?
The AXE 5iVE R3 ESC supports only HOBBYWING XeRun AXE 4987 R3S and AXE 4274 R3 series motors. Do not assume other AXE motors are compatible simply because they share the AXE name.
What batteries does the AXE 5iVE R3 support?
This ESC supports 3–8S LiPo batteries and is rated for 220A continuous current and 900A peak current. Verify battery polarity, connector compatibility, and the requirements of your selected motor before connecting power.
Can I adjust the BEC voltage for my receiver and servos?
Yes. The BEC output is adjustable from 6V to 14V and provides 15A continuous output. Set the voltage within the operating limits of every connected receiver and servo. Follow the manual when using an external receiver power supply to avoid feeding a second supply into the BEC circuit.
How do I program the ESC?
Use the HW LINK app on an iOS or Android smartphone to adjust parameters, read ESC data, and update firmware through Bluetooth. Follow the official user manual for throttle calibration, motor rotation, and optional AUX channel setup.
Does this listing include a motor, and will the ESC fit my crawler?
This listing is for the ESC only; a motor is not included. It is designed for 1/5 and 1/6 scale crawlers using a compatible AXE motor. The ESC measures 70.2 × 56.3 × 45.5mm, including the capacitor. Check chassis clearance, mounting space, and wiring access before ordering.

Let customers speak for us
Description
The HOBBYWING XeRun AXE 5iVE R3 220A ESC is designed for 1/5 and 1/6 scale rock crawlers using a compatible AXE motor. Its FOC control and closed-loop speed regulation help you maintain a deliberate pace over changing terrain, while Bluetooth tuning lets you adjust the setup from your smartphone.
Check motor compatibility before ordering: this ESC supports only XeRun AXE 4987 R3S and AXE 4274 R3 series motors. Do not select a motor simply because it carries the AXE name. This listing is for the ESC, not a motor-and-ESC combo.
