DRONE QUESTION

[Mr_Fixit]

FYI - Hubsan drones make use of nylon gears between the motor and the prop (You can see the offset in the picture there). This makes for not only a noisy flight, but often mechanical issues develop over time. Dust and various particulates tend to build up in there. If you have even a small crash, the alignment can be compromised and cause the drone to fail or fly strangely.
