Quite a few aeroplanes will de-rig easily into a trailer or container.
If you're after a rag and tube, the most important thing is to protect the flying surfaces from UV, so whilst they can be left outdoors, really heavy lightproof covers are really important. Covering the engine and cockpit obviously makes sense as well.
Aeroplanes I particularly like at the very cheap end of this class: Thruster TST/T300, X'Air, AX3 - but there are loads of others.
This might be useful as a buyers guide.
