Bigger is
NOT ALWAYS better - it's just bigger.
If you have a love of large AC - then buy / build one! They are more stable and will fly when many others will be grounded, you will need bigger servos, motors etc - talk to a local expert or frequent the Giant Scale forums.
Other than that - they are airplanes - buy a big truck, or trailer to move them with. Have a big workshop to maintain and store them - then go flying!
