From the experience I have and reading I have done, The Falcon 3D is hit or miss. Do not buy one of the "AS IS" from Hobby Lobby unless you know what you are doing ... basically you should be buying it for spare parts if you already have one or as a second bird if you know what you're getting into.

Some people have fairly good luck with them, but I really think the threads are so long because it takes so much support to keep one even hovering. You don't see as much "chitter chatter" with other birds and I don't think it has anything to do with the love of the bird, rather with the love of the hobby and poor quality.

I have had one and can tell you the quality is no where close to something like a Align T-Rex 450 SE or SE V2. Those, of course, are more expensive....

That does not answer your question, but I would recommend something other than that -- look into another variety or look into a notch or two in quality above.
