Losi Nascar Dale Earnhardt Jr Number 8 Brushless Fail

Losi NASCAR Dale Earnhardt Jr. #8 – Full Overview, Spektrum 4500KV Conversion, DX3 AVC Install & Final Upgrade to Furitek Scorpion Pro 2
In today’s video, I’m taking the Losi NASCAR Dale Earnhardt Jr. #8 and giving it a full breakdown, upgrade path, and honest performance review. This platform already looks incredible out of the box, but I wanted to push it further with modern electronics, better control, and improved drivability on asphalt.
🔧 Spektrum 4500KV ESC/Motor Combo Conversion
I start by swapping out the stock electronics for the Spektrum 4500KV brushless system, giving the car a big bump in power and throttle response. The install includes:
• Spektrum 4500KV brushless motor
• Spektrum ESC
• Clean wiring layout
• Initial calibration and setup
📡 DX3 Transmitter + AVC Receiver Install
To get better stability at higher speeds, I install the Spektrum DX3 transmitter paired with an AVC-enabled receiver. This setup adds:
• Adjustable AVC stability control
• Smoother steering at speed
• More predictable throttle control
• Better overall handling on asphalt
🛞 Running on Losi NASCAR Soft Tires
The car is tested on Losi NASCAR soft compound tires, giving it:
• Improved grip
• More consistent cornering
• Better acceleration without excessive wheelspin
⚠️ Real‑World Issues With the Spektrum Combo
After several runs, I ran into multiple issues with the Spektrum system. Because of that, I decided to move to a more reliable setup.
🔥 Final Upgrade: Furitek Scorpion Pro 2 Combo
To solve the problems and unlock smoother power delivery, I converted the car to the Furitek Scorpion Pro 2 brushless combo. This upgrade brings:
• Ultra‑smooth throttle control
• Better low‑end torque
• Cooler temps
• More consistent performance overall
