SIYI mainly focuses on manufacturing professional remote control systems and air units (receivers), but it seems they do not produce motors. Their systems are crafted for long-range, high-definition control of drones, unmanned vehicles, and robotics. They offer a variety of Remote Controllers (Transmitters), including the MK32 Enterprise and MK15 / MK15E, along with Receivers (Air Units) and more. You can find high-quality options exclusively at RCProduct.in.
