SkyRC Supa Combo 60A 4000kV
Description
The SkyRC FuriaX Supa Combo combines the powerful FuriaX Supa 60A Brushless ESC with the FuriaX Supa 3650 4000kV Motor to create a perfectly matched setup for 1/10 RC vehicles. The system delivers strong and consistent acceleration, precise control, and efficient cooling ideal for touring cars, buggies, and short course trucks. With convenient app-based programming, all performance parameters can be easily adjusted via smartphone, while multiple protection features ensure maximum reliability and safety.

Key Differences Comparison
RPM and Top Speed:
- The 5400KV motor will spin faster per volt applied than the 4000KV motor.
- On a standard 2S (7.4V) LiPo battery, the 5400KV motor has an unloaded top speed of 39,960 RPM, while the 4000KV motor reaches 29,600 RPM.
Torque and Acceleration:
- Lower KV motors (4000KV) generally provide more torque per amp, making them better suited for heavier vehicles or rapid acceleration from a stop.
- Higher KV motors (5400KV) have lower starting torque and may struggle in heavy cars, potentially causing "cogging" or stuttering at low speeds.
Heat and ESC Load:
- The 5400KV motor draws more current to produce the same amount of torque as a lower KV motor.
- With a 60A ESC, a 5400KV motor is more likely to cause overheating or trigger the ESC's thermal protection if it is not geared down (using a smaller pinion gear).
Efficiency and Runtime:
- The 4000KV motor is typically more efficient, leading to longer run times on the same battery.
- High KV motors like the 5400KV sacrifice efficiency for pure speed and responsiveness, draining batteries faster.
Application Recommendations
- Choose 4000KV if: You want a reliable, "all-rounder" setup for a 1/10 scale basher or buggy. It runs cooler and is easier on your 60A ESC.
- Choose 5400KV if: You have a very lightweight 2WD vehicle and prioritised high-speed runs on flat pavement. You must use a smaller pinion gear to prevent the motor and ESC from burning out.
