[Custom] DT-04 ESC Install Hack: Fit the 10BL120 G2 without changing your battery

Customize

Installing an ESC into the DT-04 chassis is always a space-saving challenge.

Usually, this requires switching to shorty LiPo packs to make room.

Here, I’ll share a simpler way to mount the ESC without large modifications.

ESC Selection and Fan Low-Profile Hack

The ESC used is the “HOBBYWING QUICRUN 10BL120 G2”.

This ESC is high-performing and one of my favorite units.

As a clever trick, I swapped out the cooling fan to save space.

Replacing the stock fan with this 7mm low-profile fan from Eagle Model.
This swap reduces the ESC height by approximately 3mm.

The stock fan is 10mm tall, but swapping to a 7mm fan saves 3mm.

This small difference is crucial for clearing the body shell.

Layout Strategy: Relocating the Receiver

The stock ESC location interferes with the body switch mounting.

The manufacturer’s manual location conflicts with the switch bracket.

To solve this, I moved the receiver to the opposite side of the chassis.

Placing the ESC in the receiver’s original spot provides better space.

Moving the ESC to the original receiver position provides ample clearance.

It’s a clean and effective relocation that keeps the center of gravity balanced.

Final Assembly and Fitment

With the 3mm height reduction, the cover closes perfectly.

Thanks to the low-profile fan, the cover snaps on without any binding.

This method avoids expensive battery pack changes.

The build is clean, even without the driver figure.

I also swapped to the “QUICRUN 3652 G2” motor.

It’s a direct fit, making this a powerful and efficient brushless upgrade.

Conclusion

You can optimize the DT-04’s layout with a few smart adjustments.

This approach saves you the cost and hassle of replacing your batteries.
