Features:

• (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) 30.5mm installation hole spacing is more suitable for large-sized load-type flight vehicles and is easy to install.
  
• (5) The angled extended large-area pad design not only makes the motor circuit layout more refined, but also effectively simplifies the welding process.
