Why doesn't it fly?
I have had the cyclone quadcopter for a few years and recently it has stopped working as well. By that I mean it can take off but it doesn't have nearly as much power as it would normally. originally it seemed like one of the motors was the issue so I replaced that motor. That issue seems to be fixed but now the seem to all be at the same level of lower power. I still have a spare motor (they are the correct direction) for each other rotor which I haven't replaced yet. Is the motor the issue or is it something else?
Is this a good question?
