With so many phantoms being crashed, why not a full exterior crash/roll cage? I know weight is a big concern, but i would think something made from aluminium wouldnt be too heavy. I would prefer the added weight for the extra protection you get. I'm not saying something crazy with tubes running everywhere, something basic, but strong enough to protect, like a square box shape. I know there are good pilots out there that have never crashed. But even the best race car drivers in the world have a roll cage for protection.
