I am a three week old owner of the Q5004K, no complaints. So far, my maiden flight and successive flights are all successful. No crashes, knock on wood. Make sure you guys register your quads via this FAA link: Aircraft Registry – Aircraft Registration: Unmanned Aircraft (UA) I tried the multiple screens by downloading the CG03 app in the apple app site. Not quite a consistent link with the mini iPad but a little consistency on the iPhone 6 plus. I read a lot of mods for increasing wifi and sat signals and I am waiting for Yuneec for a FW patch for increasing signals, if they ever will.
