Blueson A1 4-in-1 ESC 2-8S 70A (20x20)

Product Description:

(1) High-quality ultra-high copper thickness PCB ensures the current carrying capacity while improving heat dissipation. Equipped with top-level MOSFET, it enhances flight performance and makes you enjoy the fun of flying in the air.
(2) Equipped with a high-speed 32-bit processor, it supports full-segment dynamic PWM variable refresh rate of 8KHz-128KHz, with more precise speed response and smoother throttle control.
(3) Supports 6S/8S wide range voltage input, allowing your aircraft to adapt to power batteries of different specifications, improving the versatility of the device.
(4) With 20*20mm installation hole spacing, it is tailor-made for racing drones and easy to install.
(5) ESC reserves a large area of solder pad to effectively reduce the difficulty of soldering.
