本模型参考@EricMH的模型(https://makerworld.com/zh/models/84174#profileId-89969)进行设计，其原因在于无法购买到@EricMH模型中的航模发动机，故本模型使用的为外径20mm内径16mm的玻璃纤维自制的航模发动机。

This model is designed with reference to the @EricMH model (https://makerworld.com/zh/models/84174#profileId-89969). The reason is that it is impossible to purchase the airplane model engine in the @EricMH model, so this model uses a glass fiber self-made airplane model engine with an outer diameter of 20mm and an inner diameter of 16 mm.
