The steering engine in the prior art is driven by adopting a rotary potentiometer and a driving plate integrated with a silver film and a carbon film, but the former has overlarge volume and the weight is difficult to control; the latter has high production cost and complex manufacturing process, is not suitable for industrialized mass production, and has the problems of solving the defects after long-time use of the silver film and the carbon film, easy damage of the electric brush and the like.

The rotary potentiometer used in the traditional steering engine is not adopted, meanwhile, a heavy reduction gearbox mechanism is omitted, a traditional steering engine circuit board is changed into a driving board integrated with a silver film and a carbon film, the structure is simplified, and the higher integration level is obtained. The weight is lighter than that of the traditional steering engine, and the microminiaturization of the model airplane is greatly promoted. However, the above patent also has the following disadvantages: (1) Silver films and carbon films are printed on the driving plate, so that the method is not suitable for industrial mass production, and the reject ratio of products is high; (2) The gap between the sliding block and the bracket is large, and the silver film and the carbon film easily enter foreign matters, so that the brush and the silver film/carbon film are in poor contact and even damaged. (3) The brush is in direct contact with the silver film/carbon film, and the film coating is easy to damage after a long time, so that the precision is greatly reduced or the steering engine cannot be used at a certain point. (4) The electric brush belongs to a vulnerable part, and is easy to rebound due to overlarge stress. The production process is complicated and the cost is increased. (5) The electric brush is in direct contact with the silver film/carbon film, and a certain friction resistance moment exists, so that the actual output moment of the steering engine is reduced. The probability of heating and locking of the steering engine is increased. Thus, the first and second substrates are bonded together,
