I see Hobbyking have come out with a Naza knockoff. It's well cheap for a GPS FC. I might bag one and try it on a scratchbuilt and see how it flies.

Also, what's with the troll face on top of the blue cage?
Reminds me, I need to get a balancer. Anyone recommend a decent affordable one that does the job?
