This combination is often chosen for endurance and steady flight characteristics, rather than pure speed or aggressive acrobatics, making it ideal for a beginner’s first Y3 tricopter.
Propellers: Fiber 13×5
Propellers are the direct interface between your tricopter’s motors and the air, translating rotational energy into lift. The 13×5 fiber propellers used in this build are quite significant in size, reinforcing the choice of 750kv motors. The “13” denotes a 13-inch diameter, while the “5” refers to a 5-inch pitch, meaning that for every rotation, the propeller ideally moves 5 inches forward through the air.
Large propellers like these are highly efficient at lower RPMs, contributing directly to longer flight times and stable flight. Their fiber construction offers a good balance of durability and lightness, crucial for crash resistance during early flights. Proper propeller selection ensures that the motors operate within their optimal efficiency range, preventing overheating and maximizing overall performance for the Y3 tricopter.
ESCs: 30amp
Electronic Speed Controllers (ESCs) are vital components that translate the signals from your flight controller into precise motor speeds. Each motor on your Y3 tricopter requires its own ESC to function correctly. The 30-amp ESCs specified in the video are capable of handling a continuous current of 30 amperes, providing a significant power reserve for the 750kv motors and large propellers.
It is always recommended to select ESCs with an amperage rating safely above your motors’ maximum continuous current draw. This generous rating ensures that the ESCs do not overheat or fail under load, which is a common cause of multirotor crashes. A robust ESC setup contributes significantly to the reliability and safety of your first Y3 tricopter flights, allowing for stable power delivery to each motor.
Servo: Corona Digital 12g
The distinctive feature of a Y3 tricopter is its tilting rear motor, which enables yaw control, and this functionality is powered by a servo. The Corona Digital 12g servo mentioned is a lightweight yet precise component, crucial for the agility of the tricopter. Digital servos typically offer faster response times and greater holding power compared to their analog counterparts, providing better control authority.
The “12g” refers to its weight, indicating it’s a compact unit suitable for minimizing overall aircraft mass. Precise and quick servo movements are essential for maintaining stable yaw control, especially during maneuvers or in windy conditions. Selecting a high-quality, responsive servo like this significantly enhances the flight characteristics and stability of your Y3 tricopter.
The Heart of the System: KK2.1 Evolution Flight Controller
The KK2.1 Evolution flight controller serves as the brain of this Y3 tricopter, processing commands from the pilot and stabilizing the aircraft in flight. This particular controller is renowned for its user-friendly interface, featuring an on-board LCD screen and buttons that allow for direct configuration without needing a computer. This makes it an excellent choice for beginners eager to understand their flight settings.

For a Y3 configuration, the flight controller manages the tilting servo along with the motor speeds to achieve stable flight and accurate yaw control. Learning to calibrate and fine-tune your flight controller is a key step in mastering your custom Y3 tricopter.
Receiver & Radio: X8R FrSky and Taranis
Communication between the pilot and the tricopter is handled by the radio system, comprising a transmitter (radio) and a receiver. The X8R FrSky receiver and Taranis radio combination are highly regarded in the RC community for their reliability, range, and advanced features. FrSky Taranis radios are popular among hobbyists due to their open-source firmware, extensive customization options, and competitive pricing.
The X8R receiver pairs seamlessly with the Taranis radio, providing a robust and interference-resistant connection. This dependable link is critical for safe flight, ensuring that your commands are transmitted accurately and consistently to the tricopter. A reliable radio system is an investment in both the performance and the safety of your Y3 tricopter, especially during its initial flights.
