I don't think you'll find a bunch of threads here regarding the DJI's. If they are scratch built with balsa, and flown with nitro or gas engines, perhaps.

Try this thread:

There is a DJI support guy in the thread, Blade Strike is his name. Thankless job....but he seems to be extremely responsive. The thread is huge, and moves very quickly.

You might have bought a dud, it's been known to happen. Might just return it. Good luck either way.
