Extreme Power Delivery

The 5139 90A ESC is built for demanding FPV setups, providing 90A continuous current per channel (100A peak). With a 2S-8S LiPo input range, it’s ideal for large, power-hungry drones, aggressive freestyle maneuvers, and high-speed racing, ensuring reliable high-current performance.

Premium Construction for Enhanced Durability

This ESC features an 8-layer PCB with 3oz thickened copper, boosting current handling and heat dissipation. Imported 40V MOSFETs, an industrial-grade LDO, and Japanese Murata capacitors ensure long life and stability. Dual metallized solder pads prevent lift-off, enhancing mechanical integrity.

Smooth and Responsive Performance

Powered by an EFM8BB51 main control chip at 50MHz with BLHeliSuite-configurable firmware, the 5139 90A offers precise motor control. It supports PWM, Oneshot125/42, Multishot, and Dshot150/300/600. Hardware PWM reduces noise, while Damped Light enables sensitive braking for enhanced control.

Powerhouse

This HAKRC 5139 is a monster! My 8S 3108 quad lifts heavy payloads effortlessly with the 90A rating. DShot600 is razor-sharp, and the 8-layer PCB keeps it cool. Soldering was easy with double metallized pads. BLHeli_S setup was quick—perfect for heavy-lift drones!

Thank you for the incredible review! We’re thrilled the HAKRC 5139’s power is meeting your needs. Your feedback means a lot!

Easy Install

Great ESC for my 7S racer. The 90A 4-in-1 is powerful, and soldering pads are rock-solid. DShot300 is smooth, but the 56x52mm size was a tight fit for my frame. BLHeli_S setup took some tweaking. Reliable and cool-running, but smaller size would help.

Thanks for your feedback! We’re sorry the size was challenging. We’re exploring compact designs and will email you with updates. Appreciate your support!

Pricey

The HAKRC 5139 is solid for my 8S heavy-lift quad—90A handles 3108 motors well, and DShot600 is fast. Soldering was easy, but the price is steep for budget pilots. Instructions could be clearer too. Still, it’s reliable and worth it for performance.

We appreciate your honest review! We’re sorry the price and instructions fell short. We’re working on cost and guide improvements and will email you updates. Thanks for choosing us!

Pro Performance

As a racer, I’m blown away! The HAKRC 5139 powers my 8S 2550kV setup flawlessly. The 3oz PCB and Murata capacitors keep it stable, and DShot600 is instant. Soldering pads are sturdy, and regenerative braking extends flights. Top choice for competitive builds!

Thank you for the fantastic review! We’re thrilled the HAKRC 5139 is elevating your races. Your feedback means a lot!

Rock Solid

This ESC is a tank! I’ve hammered it on an 8S 2806.5 setup for weeks—no heat, no failures. The 8-layer 3oz PCB and 40V MOSFETs are premium. DShot600 is spot-on, and double pads made soldering clean. Best ESC for high-power drones!

Thank you for the stellar review! We’re thrilled the HAKRC 5139’s durability is impressing you. Your feedback keeps us motivated!
