G'day Steve,
I had a good look at both this frame, and many others when I settled on the Alien 560 quad from Hobbyking.

Having said that I would choose the following frame over the Hobbyking Alien 560 anyday. Very similar but the crab landing gear is apparently not a 'brittle' as the Hobbyking Alien.
http://www.goodluckbuy.com/atg-tt-x4-12-reptile-4-axis-quadcopter-folding-frame-kit-with-tall-landing-skid-gear-gopro-ptz.htmlThe amount of space on these frames influenced me so much that the next frame I bought was the Reptile-Aphid from Goodluckbuy.
http://www.goodluckbuy.com/reptile-aphid-x450-fpv-quadcopter-aircraft-frame-kit-with-700tvl-camera-lens.htmlNow this frame is a ripper. It comes with a built in 700tvl FPV camera on a single axis tilt servo that I have hooked up to the flight control board (APM 2.6) and channel 8 on my radio (trimpot). It has allowed all my electronic hardware to be mounted within the frame in an extremely tidy manner.
Have a look at some of the frames on Goodluckbuy. Search for 'quadcopter frame'. They have some great frames that have varying amounts of real estate to mount all of the electrical components and many come with gimbals. A bit more expensive than Hobbyking, but a far greater choice of frame types and sizes. The built in FPV camera is a brilliant idea, and one that I will look for options for first in the future. The reason being that the in-built FPV cameras seem to fit like a glove and because this is typically what we are trying to do, why stuff around doing it yourself.
Here are a couple of pictures on my new Reptile-Aphid. Note, I've changed the arms because the frame comes with black acrylic (I think) arms which appear quite brittle, so I swapped them over to red/white nylon arms.
Short of a bit of velcro for holding the battery in place, this frame is now ready to fly. I'm hoping to get some video this weekend. (And yes, the yellow legs are tent pegs from our ensuite tent, never used the bloody thing that often anyway. And who showers when they go bush anyway?)
Cheers, Marschy
