I rec'd my Edge 540 today and my first impression is... well....I'm impressed! The quaility of the kit is fantastic, sans instructions. I haven't had much time to go into a detailed inspection, but the lack of pages for instructions leads me to think this is not one of the simpler ARF's. I did take a good look at the fuse and tail assembly. I liked the solid tail surfaces and the setup in the fuse for the radio gear.
