The wire 1 is electrically connected to the disk connection frame seat 4 through the resistance coil 2.
[0020] Because the torque of the propeller seat of the model aircraft is often caused by the high torque rotation of the motor shaft, it is not matched with the high-efficiency motor and cannot be used, resulting in the use of a low-speed torque motor. When the model aircraft is launched, the propeller blades are prone to accidental falling and damage due to excessive wind pressure in the airflow layer, which makes the propeller blades unable to stabilize the torque model aircraft body.

The coil body 22 and the resistance block 23 are interference fit. The coil body 22 is electrically connected to the carbon brush plate 45 through the resistance block 23.
[0023] The inner shaft ring opening 43 is a wide shaft ring opening structure with a centrally locked axis and a thick wheel surface, which facilitates the inner shaft ring opening 43 and the strip sheet metal 44 to be combined to lift and press the model aircraft blade base stably and efficiently, and improves the flexible adaptability and bearing performance of the torsion connector. The strip sheet metal 44 is a sheet metal structure with through holes at both ends and a long strip in the middle, which facilitates the inner shaft ring opening 43 and the strip sheet metal 44 to be combined to lift and press the model aircraft blade base stably and efficiently, and improves the flexible adaptability and bearing performance of the torsion connector.
[0024] The carbon brush plate 45 has a composite carbon brush plate surface structure with a wide upper curved leg and a narrow lower end, which facilitates the carbon brush plate 45 and the coil body 22 to form the stability of the motor's high and low frequency matching torque synchronous electromagnetic movement under the relay transition of the resistor block 23. The coil body 22 has a spiral coil structure with narrow copper core wires obliquely pulled and centrally wound and widened at the upper left and lower right corners, which facilitates the carbon brush plate 45 and the coil body 22 to form the stability of the motor's high and low frequency matching torque synchronous electromagnetic movement under the relay transition of the resistor block 23.
[0025] The staff assembles the coil body 22 and the resistor block 23 of the resistor coil 2 connected in series with the wire 1, and allows the resistor block 23 to cooperate with the reinforcing rib frame plate 3 to surround the bearing seat 41 built into the disk connecting frame seat 4, and then forms the load-bearing of the torsional connection of the model aircraft blade base through the inner clamp ring 5 and the outer frame shell seat 6, so that the high-efficiency motor shaft moves in the inner shaft ring 43 to rotate and drive the strip sheet metal 44 and the carbon brush plate 45 to work in conjunction, so that the rivet 42 reinforces and stabilizes the carbon brush plate 45 and the resistor coil 2 to perform high torque matching and synchronous working effects, ensuring the stability of various high and low frequency motor shafts connecting the model aircraft blades, and improving the flexibility of the blade torsional connectors, so that the coil body 22 and the resistor block 23 are distributed in multiple groups to increase the voltage and torque bearing values, and the inner shaft ring 43 and the strip sheet metal 44 are superimposed and pressed to prevent the shaft from coming off efficiently.
