Remove the battery and store inside. Receivers, Servos etc should be fine. A wood framework will suffer the most with changes in temperature and humidity. In a garage situation where the door is opened frequently would be the worst. Fluctuations will also cause problems with wood joints and covering wrinkles. If this is the case covering with tarp etc may help. Check all connectors before you fly as well as for other damage. I have heard of mice entering a plane and chewing the receiver antenna in two.
