Background

The current use situation of the power duct manufacturing materials in the remote control model industry is divided into two categories, namely all-metal and plastic. The cost of plastics is low but the problems are:

second, the smaller the clearance between the blades and the main cylinder wall, the higher the effectiveness of the bypass. Because of the forming process and deformation characteristics of plastics, manufacturers have to reduce the gap between the large and broad blades and the main cylinder wall;

thirdly, when the duct works, the power motor generates heat, and when the working temperature of the motor is high, the motor mounting hole is melted, so that the axle center of the blade is deviated to cause damage or flight accidents.

All-metal also has its inherent disadvantages:

firstly, the difficulty of dynamic balance is increased;

secondly, the motor and the metal duct are both metal, so that resonance is difficult to eliminate during working, and the resonance can sometimes cause adverse effects on normal flight of the model;

fourthly, the weight of the product is larger than that of the plastic;

fifth, manufacturing costs and prices are high.
