Hello I am new to this whole quad thing. I have bought an arf quad(Redcon Phoenix 210) and I am having a some issues. I got it today and plug it in and it had libre pilot on it. I got it setup and every thing worked except that on motor spun backwards not that hard to fix. I then downloaded beta flight so I could configure things more easily and now only one motor spins up and the other three do nothing else. Pls Help.
