Building on my previous speed test, I’ve taken this build to the next level.
This time, I performed a full “brushless motor upgrade” on the DT-04.
Let’s see how much top speed we can gain with high-power electronics.
Brushless System Components

I replaced the stock-style setup with a high-output brushless system.
The core components used for this upgrade are:
- Motor: HOBBYWING QuicRun 3652SL G2 4000KV
- ESC: HOBBYWING QuicRun 10BL120 G2

Speed Run at the Park: The Results
With everything prepped, I headed to the park for a high-speed test run.
Managing the explosive acceleration required careful throttle control.

The result: an incredible **47.4 km/h**!
This completely shatters my previous record of 38.7 km/h.
The performance boost from the brushless conversion is undeniable.
Conclusion
Going brushless on the DT-04 delivered phenomenal results.
Hitting 47.4 km/h provides an absolute adrenaline rush for an off-road buggy.
Stay tuned as I look for more ways to tweak the setup and push for an even higher record!
