1.模型飛機放置 ：

　　1. Model airplane placement:

　　盡量將模型飛機置于干燥環境中，最好將其放在水平托架上，或在機體內部放一些成品干燥劑。干燥的外部環境可以保證模型飛機不會因長時間放置產生變形。

　　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.飛行后的養護 ：

　　2. Maintenance after flight:

　　每次飛行結束，操縱者都應對模型飛機做保養擦拭。如果是電動模型飛機，可選用質地柔軟的除塵毛巾擦拭浮灰。如果是油動模型飛機，則應先用濃度較高的酒精噴涂在機體表面稀釋油污，然后用除塵毛巾反復多次擦拭干凈。如不及時清理模型飛機表面的油污，很容易造成機體的腐蝕。

　　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.定期涂蠟保護 ：

　　3. Regular waxing protection:

　　由于目前市面上可以購得的F3A模型飛機套材，其表面涂裝均采用了噴漆工藝，因此需要做定期涂蠟保護。機體表面的定期涂蠟養護，不僅可使模型飛機更加光潔靚麗，還可在其上形成一層保護膜，隔絕保護涂裝漆面。

　　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.設備檢查與準備 ：

　　4. Equipment inspection and preparation:

　　每次飛行前，對航模進行全面檢查，包括機身結構完整性、電機運轉、螺旋槳緊固、電池電量、遙控器信號、各傳感器工作狀態等。確保所有部件正常運作，無松動、破損現象。備用配件攜帶：攜帶必要的備用配件，如備用電池、螺旋槳、遙控器電池、工具箱等，以便在飛行中遇到問題時及時更換或維修。設備校準：根據航模類型，進行必要的飛行控制系統、陀螺儀、磁羅盤等傳感器校準，確保飛行姿態穩定，遙控指令響應準確。

　　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.電池的保養 ：

　　5. Battery maintenance:

　　避免滿電。長期不使用時，應將鋰電池取出，置于陰涼干燥處。切不要進行冷凍，避免水氣侵蝕。避免放在高溫的汽車內使用。如長時間保存，將電池充到40%后放置，或者電壓保存在3.75-3.85V之間。給電池充電，最好用小電流來充電，一般用0.5C-2C充電，小電流刺激性小，能更好的保護電池。避免過充過放，一般設置的充電截止電壓為：4.25V，放電截止電壓為：3.0V左右，放電的截止電壓，還要根據實際情況來定，比如玩3D，那么放電的截止電壓最好設置在3.4V左右，低于這個值，很容易由于瞬間的過放而造成整組電池過放了。

　　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.避免油脂殘留 ：

　　6. Avoid oil residue:

　　每次拿模型的時候應帶好手套，保存時放在盒子里，避光避潮。因為手上的油脂殘留在機身表面會造成起疹子。

　　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.

　　通過以上這些保養措施，可以有效地延長大型飛機模型的使用壽命和保持其良好的飛行性能。

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