So humour me Acerc, what would you use and how for a 30cc plane?

Honestly, this is my first 'giant' scale plane and I'd like to protect my investment a little rather than risk it. 

And yeah, I understand that the best protection is not to fly it at all but that's not an option so any protection while it's airborne is good by me. 

Besides, I figure that I'm learning right now for the even more appropriately named giant scale airplanes.
