I flew it as soon as I had enough perks to get one (I usually don't have enough, I doubt I do right now). I topped off the ol' fuel tank, took her up for a fantastic flight, dove towards an enemy plane and promptly planted it like a seedling tree. The good news was that I was able to water my new sapling with my tears. So I say go for it, knock yourself out, it's only a cartoon plane and the pain goes away quicker than you might think.
