1.模型飞机放置 ：

　　1. Model airplane placement:

　　尽量将模型飞机置于干燥环境中，最好将其放在水平托架上，或在机体内部放一些成品干燥剂。干燥的外部环境可以保证模型飞机不会因长时间放置产生变形。

　　Try to place the model airplane in a dry environment, preferably on a horizontal rack or with some finished desiccants inside the aircraft. A dry external environment can ensure that the model aircraft will not deform due to prolonged storage.

　　2.飞行后的养护 ：

　　2. Maintenance after flight:

　　每次飞行结束，操纵者都应对模型飞机做保养擦拭。如果是电动模型飞机，可选用质地柔软的除尘毛巾擦拭浮灰。如果是油动模型飞机，则应先用浓度较高的酒精喷涂在机体表面稀释油污，然后用除尘毛巾反复多次擦拭干净。如不及时清理模型飞机表面的油污，很容易造成机体的腐蚀。

　　At the end of each flight, the operator should perform maintenance and wiping on the model aircraft. If it is an electric model airplane, a soft dust removal towel can be used to wipe off the floating dust. If it is an oil powered model aircraft, it should first be sprayed with a high concentration of alcohol on the surface of the aircraft to dilute the oil stains, and then repeatedly wiped clean with a dust removal towel. If the oil stains on the surface of the model aircraft are not cleaned in a timely manner, it is easy to cause corrosion of the aircraft body.

　　3.定期涂蜡保护 ：

　　3. Regular waxing protection:

　　由于目前市面上可以购得的F3A模型飞机套材，其表面涂装均采用了喷漆工艺，因此需要做定期涂蜡保护。机体表面的定期涂蜡养护，不仅可使模型飞机更加光洁靓丽，还可在其上形成一层保护膜，隔绝保护涂装漆面。

　　Due to the surface coating of F3A model aircraft sets currently available on the market using spray painting technology, regular waxing protection is required. Regular wax coating and maintenance on the surface of the aircraft can not only make the model aircraft smoother and more beautiful, but also form a protective film on it to isolate and protect the painted surface.

　　4.设备检查与准备 ：

　　4. Equipment inspection and preparation:

　　每次飞行前，对航模进行全面检查，包括机身结构完整性、电机运转、螺旋桨紧固、电池电量、遥控器信号、各传感器工作状态等。确保所有部件正常运作，无松动、破损现象。备用配件携带：携带必要的备用配件，如备用电池、螺旋桨、遥控器电池、工具箱等，以便在飞行中遇到问题时及时更换或维修。设备校准：根据航模类型，进行必要的飞行控制系统、陀螺仪、磁罗盘等传感器校准，确保飞行姿态稳定，遥控指令响应准确。

　　Before each flight, a comprehensive inspection of the aircraft model is conducted, including the integrity of the fuselage structure, motor operation, propeller fastening, battery level, remote control signals, and the working status of various sensors. Ensure that all components are functioning properly without any looseness or damage. Carrying spare parts: Carry necessary spare parts such as spare batteries, propellers, remote control batteries, toolboxes, etc., so that they can be replaced or repaired in a timely manner when encountering problems during flight. Equipment calibration: Based on the type of aircraft model, perform necessary calibration of flight control systems, gyroscopes, magnetic compasses, and other sensors to ensure stable flight attitude and accurate response to remote control commands.

　　5.电池的保养 ：

　　5. Battery maintenance:

　　避免满电。长期不使用时，应将锂电池取出，置于阴凉干燥处。切不要进行冷冻，避免水气侵蚀。避免放在高温的汽车内使用。如长时间保存，将电池充到40%后放置，或者电压保存在3.75-3.85V之间。给电池充电，最好用小电流来充电，一般用0.5C-2C充电，小电流刺激性小，能更好的保护电池。避免过充过放，一般设置的充电截止电压为：4.25V，放电截止电压为：3.0V左右，放电的截止电压，还要根据实际情况来定，比如玩3D，那么放电的截止电压最好设置在3.4V左右，低于这个值，很容易由于瞬间的过放而造成整组电池过放了。

　　Avoid fully charged. When not in use for a long time, the lithium battery should be removed and placed in a cool and dry place. Do not freeze to avoid moisture erosion. Avoid using in cars with high temperatures. If stored for a long time, charge the battery to 40% and place it, or store the voltage between 3.75-3.85V. It is best to charge the battery with a low current, usually 0.5C-2C. Low current has less stimulation and can better protect the battery. To avoid overcharging and overdischarging, the charging cut-off voltage is generally set at 4.25V, and the discharging cut-off voltage is around 3.0V. The discharging cut-off voltage also needs to be determined according to the actual situation. For example, when playing 3D, it is best to set the discharging cut-off voltage at around 3.4V. If it is lower than this value, it is easy to cause the entire battery pack to be overdischarged due to instantaneous overdischarging.

　　6.避免油脂残留 ：

　　6. Avoid oil residue:

　　每次拿模型的时候应带好手套，保存时放在盒子里，避光避潮。因为手上的油脂残留在机身表面会造成起疹子。

　　Wear gloves every time you pick up the model and store it in a box, away from light and moisture. Because residual oil on the surface of the body can cause rashes.

　　通过以上这些保养措施，可以有效地延长大型飞机模型的使用寿命和保持其良好的飞行性能。

　　Through the above maintenance measures, the service life of large aircraft models can be effectively extended and their good flight performance can be maintained.
