4.2 Cleaning and Storage
- Cleaning: Use a soft, dry cloth to wipe down the airplane after use. Avoid using harsh chemicals or excessive moisture.
- Storage: Store the airplane and remote controller in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries from the remote controller if storing for extended periods to prevent leakage.
- Repairs: Minor damages to the EPP material can often be repaired using foam-compatible glue.
