It is spinning around because one of the rotors is not spinning at full speed. This happens when you bump a spinning rotor against something. Determine which one it is by observation or logic (i.e, the one that turns clockwise will produce counterclockwise torque, which is to be balanced by the other rotor spinning counter clockwise. So the counter clockwise spinning rotor is slow) Tighten the screw that holds that rotor that is spinning more slowly. Use the screwdriver that came with the spare parts.

The small metal piece that goes from the bottom propeller to the top seems to not catch. I wonder if that's what is causing the issue. Not sure how to tighten that. I don't see any screws in that section. Could it be broken? The small metal piece that goes from the bottom propeller to the top seems to not catch. I wonder if that's what is causing the issue.
